15. Chapter 1 About Portlock Storage Manager
What is Portlock Storage Manager?
Portlock Storage Manager is software designed to optimize server and desktop storage and protect
critical business data. Users can copy, create, clone, image, restore and resize partitions and volumes.
Recovery of failed servers is very fast and dramatically simplified. Portlock Storage Manager
supports creating images of Linux, NetWare and Windows servers (Windows currently in Beta).
Images can be stored on disk files, TCP/IP communication links, FTP servers and SCSI tape drives.
Third-generation imaging technology supports streaming to the fastest SCSI tape drives or using
high performance communications over TCP/IP for server-to-server cloning.
Portlock Storage Manager provides full-featured control over the size and layout of partitions,
volumes, NSS (Novell Storage Services) volumes and NSS Storage Pools. Compaq, IBM and DELL
Diagnostic partitions are also supported. With Portlock Storage Manager 4.0, NetWare and Linux
customers have a backup, storage management and disaster recovery solution that provides support
for imaging, moving, managing and recovering Novell Storage Services (NSS) pools, volumes and
partitions on both SUSE LINUX and NetWare system kernels. In addition, Portlock Storage Manager
supports all other leading filesystems, such as Reiser, Ext2, Ext3, etc.
Design Philosophy of Portlock Storage Manager
Portlock Storage Manager breaks commands into groups of commands based on the concepts of
Drive, Partition, Volume, Pool, Image, Restore and Repair. For example, if you want to resize a
volume, use the command Volume Resize, located under Volume Commands. If you want to resize a
partition, then use the command Partition Resize under Partition Commands. Before you can modify
a storage item, you must select it. Once an item is selected, a command menu will be displayed with
the supported commands for that item.
NOTE: Not all features are available for all file system
types.
Before Loading Portlock Storage Manager
We recommend installing the latest Service Packs, especially if you are using NSS. However, this
is not a requirement. Our Quality Assurance Department attempts to test Portlock Storage Manager
on all versions of NetWare with all Service Pack releases.
Verify your NetWare and NSS volumes prior to modifying them with Portlock Storage Manager.
Portlock Storage Manager performs a volume check on Traditional and NSS volumes prior to
beginning any modification operation. This ensures that there is no volume corruption and ensures
that Portlock Storage Manager supports the feature set of the volumes. Novell is constantly improving
NetWare and this may result in new file system features being added. Portlock Storage Manager
checks every data structure in a volume to ensure that all features are recognized and supported.
15

16. Portlock Storage Manager 4.0 for NetWare User’s Guide
Portlock Storage Manager operates the same in all supported OS environments: Dismounting where
the underlying OS requires it. The program controls the underlying OS disk access in order to complete
its functionality. Therefore, it is generally a poor idea for end users to be connected when Portlock
Storage Manager is working on the server. Portlock Storage Manager does not require clients to
log off from the server. Servers usually do not need to be rebooted after running Portlock Storage
Manager. Only the volume being modified needs to be dismounted. However, when a volume is
dismounted, files on that volume are no longer accessible. If a volume is dismounted when files are
open, users will not be able to write to these files.
NOTE: BACKUP your data. Protect your data by maintaining
current and reliable backups before you begin any storage
management operation.
Install and use an Uninterruptible Power Supply (UPS).
Portlock Software engineers design fault-tolerant features
wherever possible in Portlock Storage Manager. However,
not every disk operation can withstand power failures.
Protect your servers and desktops with UPS devices.

Introduction to Portlock Storage Manager
Portlock Storage Manager is designed to support a large variety of bare-metal disaster recovery,
server-to-server migration and storage management operations. Users can copy, create, clone, image,
restore and resize partitions and volumes. Users can also image and restore from disk files, tape,
CD/DVD, FTP and web servers. Recovery of failed servers is very fast and dramatically simplified.
No other storage management product offers such a breadth of features.
Introduction to Portlock Remote
Portlock Remote is a Windows-based program that supports remote control of Portlock Storage
Manager. Portlock Remote executes from a DOS box on a Windows platform. You can use this
program rather than using other screen capture tools, such as Rconj or Rconsole.

Method Three: Using the directory SYS:/STORMGR
To install using the directory SYS:/STORMGR, copy the files to the SYS:/STORMGR directory on
your server. The software can also be copied to any directory on your server.
Loading Portlock Storage Manager
The default installation directory for Portlock Storage Manager is SYS:/STORMGR. To load Portlock
Storage Manager, type: load sys:/stormgr/stormgr. We recommend including the logfile command
line option: load sys:/stormgr/stormgr –logfile=sys:/stormgr.log or if you are going to manipulate
storage on the SYS: volume then save the logfile to the C: drive as shown in the Execute from DOS
line. To execute Portlock Storage Manager from DOS, type: stormgr –logfile=c:/stormgr.log. As
a shortcut, create a file in the SYS:/SYSTEM directory named stormgr.ncf. Place the following
command line into this file: load sys:/stormgr/stormgr –logfile=sys:/stormgr.log. After attempting
this procedure, you can type stormgr at the server console and load Portlock Storage Manager
without specifying the path and options.

compared, checked for errors and/or cleared of all existing data. The Drive Commands make it fast
and easy for users to work with their storage devices at the drive level without the need to worry
about partitions, volumes and files.
The Main Menu offers access to all the features of Portlock Storage Manager quickly and easily. To
access the Drive Commands, select Drive Commands from the Main Menu and press [Enter].
Inside the Drive Commands you will find information regarding your drives that currently reside
on the device selected which will include partition type, partition size, free space, drive type and
virtual environment.
If you have multiple devices in your configuration they will be listed under the Select Drive menu
as shown below. Select your desired device for a list of options.
Your list of options will include Drive Attach, Copy, Create, Expand, Information, Initialize, Compare
and Verify. Drive Attach, Copy, Create and Expand are primarily for virtual environments.
27

28. Portlock Storage Manager 4.0 for NetWare User’s Guide
You will find the rest of the Drive Commands useful for incidents such as information about your
drive or checking the sectors of your drive for errors and performance. Drive Initialize must be used
with caution because it will completely delete all partitions on your device.
Drive Initialize
The Drive Initialize command will rewrite the boot sector of a device. This will delete all partition
table information. This command is designed to be used on new devices that do not yet have a valid
partition table.
NOTE: Do not run this command on a device with valid
partitions. This will wipe your device clean.
Highlight and select the device you wish to initialize:
You will be warned that all partitions on your device will be deleted. If you proceed, you will lose
all data on your device.
28

29. Chapter 3 Drive Commands
You have the option of writing all device sectors with a data pattern. You may skip this phase. When
“Write All Device Sectors with Data Pattern” is selected, Portlock Storage Manager will start sector-
by-sector initialization of the selected disk drive.
It is not always necessary to initialize every sector of your drive. This can be a lengthy process,
depending on the size and speed of your device.
29

30. Portlock Storage Manager 4.0 for NetWare User’s Guide
Drive Sector Copy
The Drive Sector Copy command is used to copy one disk drive to another. The two drives
will be an exact copy of each other. This command is typically used during data recovery.
It should not be used as a method to make a copy of a partition. Most modern operating
systems embed information into the partitions that must be modified for correct disk cloning.
You should use the Partition or Image Commands to manage your partitions.
Drive Compare
The Drive Compare command will compare two disk drives. This command can be run after a Drive
Sector Copy to verify that the copy was successful.
NOTE: You must have two devices on your system in order
to run this command.
Select the drive you wish to make your comparison with:
30

31. Chapter 3 Drive Commands
If you are trying to compare two drives that are not the same size, Portlock Storage Manager
will prompt you with a message stating the amount of sectors that will be compared. The
size of sectors will be dependant on the size of your drives.
Drive Verify
The Drive Verify command will perform a test of the disk device. There are several types of tests,
including Read-Only and Read-Write. Read-Only commands will not modify the media, and are safe
to run when there are partitions and volumes present. The Read-Write commands are destructive
and will destroy partitions and volumes.
WARNING: Do not execute Read-Write
commands on a device with valid partitions
and volumes. Doing so will delete all data.
1. Read-Only Sequential Verify
This method performs a read-only sequential scan of the disk drive. Block sizes from 1 sector to
128 sectors per I/O are supported. No data is written to the drive. This is also a quick method to
determine the read performance of a disk drive.
2. Read-Only Random Verify
This method performs a read-only random scan of the disk drive. The software generates a random
number which determines the sector to read. Block sizes from 1 sector to 128 sectors per I/O are
supported. No data is written to the drive. This method is quick in determining the random I/O
performance of a disk drive.
31

32. Portlock Storage Manager 4.0 for NetWare User’s Guide
3. Read-Write Sequential Verify
This method verifies that data can be written to a disk drive and then read back. A data pattern that
is unique to each sector is written to the disk and then compared on read back. Block sizes from 1
sector to 128 sectors per I/O are supported. For this verify mode, an option is to perform an extensive
verify, which writes multiple data patterns to the disk drive. This includes performing a bit-walk data
pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions,
volumes and data on the disk drive.
4. Read-Write Random Verify
This method verifies that the data can be written to a disk drive and then read back. The software
generates a random number that is used to determine the sector to write/read. Block sizes from 1
sector to 128 sectors per I/O are supported. For this verify mode, an option is to perform an extensive
verify, which writes multiple data patterns to the disk drive. This includes performing a bit-walk data
pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions,
volumes and data on the disk drive.
Two options for verifying your disk drive are verifying the entire drive or part of the drive. If you
choose to verify only part of the drive, Portlock Storage Manager will prompt you for information
regarding the length of the drive verification you wish to carry out.
32

33. Chapter 3 Drive Commands
Portlock Storage Manager will give you the option of how many sectors per I/O to complete.
NOTE: Portlock Storage Manager supports various size
I/O operations. The size of an I/O is measured in sectors.
The larger the I/O size, the faster most drives can transfer
data. Most devices are limited to 128 sectors (64 KB) per I/O
operation. Some devices can transfer larger amounts.
Give Portlock Storage Manager a number of passes you wish Drive Verify to make. In most cases,
one pass is substantial.
The drive verification process will begin and may take a few minutes.

Partition Commands
The Partition Commands are designed to help you manage and diagnose problems and perform
storage management operations3 at the partition level. By selecting the Partition Commands from
the Main Menu of Portlock Storage Manager, you will find a number of options to assist you in
managing your system.
Note: There are several features within the Partition
Commands that are only usable when running under a
NetWare system.
From the Partition Commands you will have the option to Activate, Check, Copy, Create, Defrag,
Delete, Dismount, Display, Format, Hide, Image, Mount, Resize and Unhide. There are many different
scenarios for each command, all of which can be beneficial when managing your system.
Activate Partition
The Activate Partition command is used to modify which partition will be set to boot in the Master
Boot Record (MBR). For example, various MS-DOS partitions could be present on a drive, but only
one could be active or able to “boot.”
35

36. Portlock Storage Manager 4.0 for NetWare User’s Guide
Portlock Storage Manager will provide you with a list of partitions to activate. Your system will not
boot from an inactive partition.
Check Partition
The check partition feature will ensure that you have no warnings or errors that reside with any of
the partitions on your device.
Portlock Storage Manager will provide you with a list of partitions on your device. Choose the
partition that you wish to check.
36

37. Chapter 4 Partition Commands
Once the partition check is complete and you have not received any notices or warnings, you will
see that everything is checked with a “Success.”
Combine NetWare 6 Master Partition
From the Select Partition Command menu, select Combine NW 6 Master Partitions and press
[Enter]. The selected NetWare 6 master partition tables will be combined and you will be returned
to the Select Partition Command menu.
NOTE: Once you’ve combined partitions, you cannot revert
those partitions to their original state.
Convert into a NetWare 6 Partition
Select the Convert into a NW 6 Partition from the Select Partition Command menu.
37

38. Portlock Storage Manager 4.0 for NetWare User’s Guide
When migrating or copying partitions, ensure that you have an activated partition. If there is no
activated partition or the correct partition is not activated, your system may not boot. Partitions
marked with an asterisk (*) are bootable partitions.
Checking your partition may be a good idea before beginning any image or copy to ensure that your
have no errors or corruption with any one partition.
Copy Partition
Choose the option “Copy Partition” as seen below. This will
allow you to copy your partition to free space on your existing
drive or to an additional device on your system. For example:
You have a 9 GB drive that is almost full and you would like
to replace this drive with a larger one. You can accomplish this
by installing a new, larger drive (if applicable) and copy the
partition to the larger drive and resize it using the Partition
Resize command.
After selecting your device, its partitions are displayed. Once you have selected the partition you
wish to copy, Portlock Storage Manager will ask you where you want to copy your partition. If you
have no other existing devices on your system, you will need to copy your partition to the original
device. You will not have the option to copy a partition if you do not have enough free space on the
original device.
Two pools with the same name cannot reside on the same server. Portlock Storage Manager will ask
you to rename the partition/pool that your are copying.
NOTE: You may rename
your partition/pool back to
its original name once the
original partition/pool has
been discarded.
38

39. Chapter 4 Partition Commands
Portlock Storage Manager checks all partitions before allowing management operations to ensure
that you are not moving or managing a potentially corrupted partition.
You will need to rename your volume just as you did for your pool because Portlock Storage Manager
does not allow you to have duplicate volume names.
Select the device you wish to copy to and ensure you have enough free space on this device before
beginning the copying process.
Upon copying your volume, you will have the option to resize your pool. Portlock Storage Manager
will provide you with a minimum and a maximum size. If you do not wish to resize, select the default
size provided and press [Enter].
The copying process will begin and may take a few minutes.
Create Partition
The Create Partition command will allow you to create partitions so that data management can
be more streamlined and changes can be made to the layout and location of your volumes and data.
This command is most commonly used to prepare an un-partitioned disk or disk with available free
space for use. A number of different partitions can be created using this command. Partitions that
can be created with Portlock Storage Manager are DOS, FAT16, FAT32, NetWare, NTFS, Linux
Swap and ReiserFS.
39

40. Portlock Storage Manager 4.0 for NetWare User’s Guide
NOTE: Portlock Storage Manager can only create a partition
if there is available free disk space to do so.
Portlock Storage Manager will provide you with a list of partition types to create. Select the type
that you wish to create and press [Enter].
Create either a NetWare Traditional or NSS partition.
Portlock Storage Manager specifies a minimum and a maximum size for your partition. Specify the
size for your new partition and press [F10].
40

41. Chapter 4 Partition Commands
Delete Partition
Deleting a partition is sometimes necessary to create free space for different scenarios. To delete a
partition, select Delete Partition from the Partitions Command menu.
The partitions you may delete are displayed:
Hide Partition
The Hide Partition command will allow you to hide partitions by changing their partition type in
the Master Boot Record (MBR). This command is most useful when copying a NetWare partition
without renaming the volumes inside of it. By hiding the partition, NetWare will not have a conflict
with volume names.
Choose the partition that you wish to hide from the selection list and then confirm the process.
41

42. Portlock Storage Manager 4.0 for NetWare User’s Guide
Image Partition
This allows you to take an image of a partition. The Image Partition command is designed to take
a sector-by-sector image of the partition. It should not be used for normal image/restore operations
as it is only designed to be used for disaster recovery in the event of a failure.
This command is intended for data recovery operations and not for duplicating partitions as most
modern operating systems embed information into the partitions that must be modified for correct
partition cloning.
Select the partition that you wish to image from the selection menu:
Portlock Storage Manager will provide you with several types of destinations to choose from. Choose
the one that best suits your needs. For more information on imaging and destination selection, please
see the Imaging Commands.
42

43. Chapter 4 Partition Commands
Resize Partition
This command resizes DOS, NetWare and NSS partitions. A partition can be
resized larger or smaller, contain one or more volume segments, be resized
by changing the starting or ending position of a partition and can also be
moved. Volumes within a partition are not resized by this command. DOS
partitions can be resized larger and smaller,
both in place and upon image restoration.
NSS partitions may only be resized larger.
However, NetWare Traditional partitions
may be resized both smaller and larger. Adequate disk space for resize-larger is needed since Portlock
Storage Manager does not move partitions for the resize process.
Portlock Storage Manager will provide you with a list of partitions to
resize. Choose the partition you wish to resize and press [Enter].
You will now be given a minimum and a maximum size that you will
be able to resize your partition. Enter the new size in MB and press [Enter].
Unhide Partition
The Unhide Partition command will do the opposite of the hide command
by reverting the partition type bit in the MBR. Do not use duplicate volume
names. Portlock Storage Manager will detect duplicate volume names and
will prevent you from proceeding until the volumes have unique names. Use
the Volume Rename Command to rename your volume.
Once you have chosen Unhide Partition, Portlock Storage Manager will show you a list of all the
hidden partitions on your device. Select
the partition you wish to unhide and press
[Enter].

Volume Commands
This chapter includes the following topics:
• Volume Check Command
• Volume Delete Command
• Volume Rename Command
44

45. Chapter 5 Volume Commands
The Volume Commands are a subset of NetWare-specific commands
that will allow the user to perform a variety of tasks on NetWare
volumes. A few of the more commonly used commands are Volume
Rename, Volume Resize/Merge and Volume Copy. If you wish to
work with volumes and not partitions, this would be the appropriate
selection. Depending on which version of NetWare you are using,
Portlock Storage Manager will present the appropriate commands
on the Volume Menu. On servers running versions of NetWare that
use NSS technology, a NSS Volume Command item will be available
from the Volume Menu.
Portlock Storage Manager will provide you
with a list of all the volumes on your server.
Select the volume that you wish to manage.
Volume Check
The Volume Check command allows a quick, comprehensive check
of the selected volume. When this command is used, Portlock Storage
Manager will read and analyze the primary FAT Table, verify the
Secondary FAT, read the directory tables and analyze the DIR Tables.
This is a read-only command that checks a volume for errors. It does
not repair any volume errors. Use the NetWare VREPAIR program
to repair a Traditional NetWare volume.
If your volume check passed without any
errors you will be able to continue with
managing your volume.
Volume Delete
This will permanently delete a volume from your pool and device.
Use this command with caution as all data may potentially be lost
Volume Rename
Enter a new volume name for your volume. This must be a
unique name for Portlock Storage Manager to accept it.

46

47. Chapter 6 Pool Commands
Introduction to the Pool Commands
The activate Pool Command will allow the user to activate the currently selected pool. Once the
user selects this option, Portlock Storage Manager will activate the selected pool and return to the
NSS Pool Command menu.
NOTE: When possible, make sure you have a verified
backup of all of the volumes in the Pool you are trying to
rebuild. A system crash that halts running processes can
cause volume errors, but they are typically repaired during
volume mount. If the errors persist, use Rebuild Pool and
Verify Pool commands to try and resolve any problems.
Check Pool
The Check Pool Command will allow the user to test the integrity of the selected pool. Some of the
tests that will be performed include Verification of NSS Partition, Super Block, Free Tree, Check
Point, Name Tree, Dir Tree, User Tree, Leaf Tree and more.
From the Select NSS Pool Command menu, select Check Pool by highlighting it and pressing
[Enter]. You will be prompted to dismount any mounted volumes before proceeding.
NOTE: The Check Pool command uses Portlock’s pool-
checking facilities with Portlock Storage Manager on a
pool and it only reads the pool and does not correct any
errors.
47

48. Portlock Storage Manager 4.0 for NetWare User’s Guide
Portlock Storage Manager will show you a list off pools that reside on your server. Choose the pool
that you wish to perform the check.
You may continue managing your pool after the pool check passes.
Copy Pool
The Copy Pool command allows you to copy an existing Pool to a new storage location on an existing
disk or a new disk. The copy will create a new pool with all of the volumes inside the pool. You will
need to assign new, unique names to the pool and the volumes inside the pool.
Portlock Storage Manager will require you to rename your pool and volume as you cannot have
duplicate pool and volume names on your server.
48

49. Chapter 6 Pool Commands
Select the device that you wish to copy your pool to. Verify that you have enough free space on your
device or Portlock Storage Manager will not allow you to begin the copying process.
Delete Pool
The Delete Pool command allows you to delete existing pools on your server. If a pool is deleted
unintentionally while using Console One, you can use Portlock Storage Manager to undelete the
pool. Select the Undelete Pool option to see which pools may be undeleted.
Move Pool
This command allows you to “move” a pool from one storage location to another. The process involves
Portlock Storage Manager hiding the original pool and copying it to the new storage location. The
moved pool is identical to the hidden pool. All rights, restrictions, etc. are preserved as part of the
move. This command is ideal when used to migrate from old storage to new storage, such as a locally
attached disk to a new SAN environment. Select Move Pool from the Pool Commands menu to
move a pool. If the move does not complete successfully, unhide the original pool and try again.
49

50. Portlock Storage Manager 4.0 for NetWare User’s Guide
After you select the pool to move and the device to move your pool to, Portlock Storage Manager
will perform a pool check to ensure your pool is in good condition before moving it.
During the pool remove you will be given the option to resize your pool. Portlock Storage Manager
will give you a minimum and a maximum size to choose from.
Once the pool move is complete you can confirm the move was a success by checking your device
and the data in your pool.

• Overview of the Image Commands
• Disaster Recovery
• Cloning a Server
• Upgrading Hard Drives
• Writing Image to a Disk Drive
• Writing an Image to a TCP/IP Link
• Writing an Image to a Tape Drive
• Writing an Image to a CD/DVD Recorder

• Online Imaging
52

53. Chapter 7 Image Commands
Overview of the Image Commands
Portlock Storage Manager images Compaq, Dell and IBM diagnostic partitions, DOS FAT-16
partitions, Traditional Volumes and NSS Volumes. The volumes within a NetWare partition are imaged,
but NetWare partitions are not imaged. Imaging the NetWare partition is unnecessary as they are
created on the fly by Portlock Storage Manager during a restore. The Image Command dismounts
Windows file systems before imaging when the Portlock Boot CD (WinPE) is used.
Portlock Storage Manager images Traditional and NSS Volumes by storing the volume ATA blocks
and file system structure into the image. This allows the volumes to be resizable during the restore.
Portlock Storage Manager implements a third-generation technology for imaging NetWare servers
that maximizes the performance of the image and restore commands. For most systems, Portlock
Storage Manager can easily stream the fastest SCSI tape drives such as Quantum’s LTO-3. An entire
NetWare server can be saved into an image that can be stored as an image file on another server or as
an image written to a SCSI tape drive. Images can consist of multiple files that are “spanned.” Spanning
supports images that are larger than the media to which they are written (i.e., CD/DVDs).
Restoring an image can be done from DOS or NetWare. An entire server or just portions of the
server can be restored from the image. Portlock Storage Manager does not support individual file
recovery from images. This is a deliberate design decision due to our goal of very high performance
and compressibility of images.
DOS FAT-32 partitions cannot be resized. This is a feature that will be added in a future release.
Compaq Diagnostic partitions are not resizable when restored. This is also deliberate, as
Diagnostic partitions are special types of partitions. Partitions can be enlarged using the Partition
Copy command.
NOTE: It is not possible to image volumes within a pool.
To move a volume from one pool to another, you need to
use the Volume Copy command.
Portlock Storage Manager images Traditional and NSS volumes by storing the volume data blocks
and file system structure into the image. This allows the volumes to be resizable during the restore.
Portlock Storage Manager can image a NetWare server while NetWare is running or from DOS.
Device drivers written for NetWare are 32-bit drivers that have been optimized for performance.
For this reason, we recommend imaging servers from NetWare instead of from DOS. DOS device
drivers are typically 16-bit, real-mode drivers that are usually optimized for small memory size, not
performance. You will often see a two-to-one performance difference between DOS device drivers
and NetWare device drivers.
53

54. Portlock Storage Manager 4.0 for NetWare User’s Guide
Portlock Storage Manager supports both the NWPA (HAM) drivers and NWIO (DSK) drivers for
communicating with tape drives. Portlock Storage Manager interfaces directly with the HAM drivers
when using the NWPA interface. When using the NWIO interface, Portlock Storage Manager uses the
ASPI interface. NWPA drivers are faster. Portlock Storage Manager only supports ASPI drivers for
communicating with tape drives under DOS. ASPI drivers provide interface to SCSI Host Adapters
that are consistent with various SCSI Controllers.
Disaster Recovery
If you are using Portlock Storage Manager to create an offsite disaster recovery image, remember that
when you restore the image, only the data present at the time you created the image will be restored.
Any newer files will not be part of the image that you have. For disaster recovery, you need to restore
the image that you made with Portlock Storage Manager and overwrite the information with the
latest version of the backup. This will provide you with all of the data up to the most recent backup
that you restored. Your only consideration is that all of your user IDs and passwords for these user
IDs will be the ones that were used when the Portlock Storage Manager image was created. Backup
software such as FutureGate’s DeTroubler® supports restoration of NDS objects, which is acceptable
in a single-server tree, but please consult your backup software manual for more information.
Cloning a Server
This method is used when you are upgrading the hardware for your server. In this case, you use
Portlock Storage Manager to create an image of the old server and restore it on your new server.
Once the image is restored to the new server, you may have to modify the server so that it supports
the new disk controller and Network Interface Card before your users will be able to login to the
server. Please consult the manuals for your new hardware to ensure you have the correct drivers
loaded for the disk subsystem under NetWare.
Upgrading Hard Drives
This is the simplest solution for upgrading your server. Create an image of your server, remove the
existing drives, install the new drives and restore the Portlock Storage Manager image, resizing the
volumes as appropriate.
The imaging process will give you the following options:
• Image entire system
• Image a single disk drive
• Create a Sector Image of a disk drive
• Create a Sector Image of a partition
• Create a Sector Image of a disk region
54

55. Chapter 7 Image Commands
Creating a sector image of a disk drive and of a partition is also the same process as the
aforementioned Drive and Partition Commands. Choose to Create a Sector Image when
you would like a bit-for-bit image. However, this command is most commonly used for data
recovery purposes and backing up a failing drive partition or region – errors and all.
When selecting to image your system your will receive a list of all the partitions that reside
on the device you selected. You may skip a partition for the imaging process by pressing F5.
By default, Portlock Storage Manager will select all partitions on your device. Press [Enter]
to image your entire server and view the image status next to each partition.
If you have volumes present, you will be asked if you wish to purge all volumes.
Write Image to a Disk File
For your imaging process Portlock Storage Manager provides you with several different
types of destinations for ease of management. Your destination selection will consist of:
• Write image to a disk file
• Write image to a TCP/IP link
• Write image to a Tape Drive
• Write image to a CD/DVD Recorder
• Write image to an FTP Server
55

56. Portlock Storage Manager 4.0 for NetWare User’s Guide
This guide will take you through each selection. For the first destination select Write image
to a disk file.
Your image can be written to a DOS partition or a NetWare volume. Specify the path for
your image and press [Enter].
Portlock Storage Manager provides you with several options pertaining to the image being created. The
first option you are given is Compression, which can be enabled or disabled. Enabling compression
will create smaller file sizes but will take longer to image and restore. Disabling compression increases
imaging and restoring speeds but results in larger file sizes.
The second option is Image File. With Image File, you may:
1. Auto-name image files. This will name the files with an increasing numeric extension for
each image file, such as .001, .002, etc.
2. Ask for new image filename when the image file is full. Enabling this will automatically
split the entire image file into 2,000 MB segments.
3. Split Image Files at 2,000 MB. This value can be changed. Enabling this will automatically
split the entire image file into 2,000 MB segments.
4. Wait after each image file change. Enabling this will pause the process after each image
file change. Since all the choices are pertinent to our example, we will press [Enter] to
continue.
NOTE: Portlock Storage Manager supports limiting the
size of each image file to any size in multiples of 1,000,000
bytes. If you want to create an image that is limited to 650
MB for writing to a CD-ROM, specify a size of 650 in the
Split. If you want to use removable media and you want to
exchange the media when full, enable the Wait after each
image file change option. If you want to write images to
a Windows partition and have Portlock Storage Manager
auto-name each file after the first one, enable the Auto-
name image files field.
56

57. Chapter 7 Image Commands
Auto-naming image files will cause Portlock Storage Manger to write with the name of the image
file that you specify. If you specified an image filename of netware.img, a new file is created with
a suffix of .000 (e.g. netware.000) when the file size limit is reached. As each file fills a new file is
created, e.g. netware.001, etc. If the disk runs out of space, you will be prompted for a new filename,
and the process can repeat on the new disk drive or volume.
NOTE: Never give the initial image file a numeric extension
as you may overwrite one of the files that you require as
part of the image. Also ensure that the image files are no
larger than 2,000 MB in size.
Portlock Storage Manager will begin the imaging process and it may take a few minutes to
complete.
Write Image to a TCP/IP Link
Portlock Storage Manager supports sending an image over a TCP/IP link. The machine that is running
on the other end of the TCP/IP link can be Portlock Storage Manager running in Restore Mode,
which implements server-to-server cloning. The other end of the TCP/IP link can also be Portlock
Image Manager, (IMAGEMGR.NLM , located in the same directory as Portlock Storage Manager)
which can receive data from TCP/IP and write it as a disk file, or write it to a SCSI tape drive. The
latter supports a multi-server environment with only one SCSI tape drive.
57

58. Portlock Storage Manager 4.0 for NetWare User’s Guide
When using Portlock Storage Manager on two servers with one executing the Image Server
command and the other server executing the Restore Server command, you can clone servers at
very high speeds. Portlock Storage Manger has been written with special performance features for
high-speed tape drives. With the increased size of disk drives and RAID arrays, classic file-by-file
backup methods are too slow.
Portlock Storage Manager can compress the image as it is being written. For a server-to-server
migration, you should not enable compression because it can slow the process down. From the
Compression Mode menu, select whether to disable or enable Software Write Compression and
press [Enter] to continue.
When transferring an image via TCP/IP, one side needs to be a server, and the other side needs to be
a client. The system that is running as a server must be started first. The system running as a server
will listen for a connection from the other system (client). Select the TCP/IP mode for this system
and press [Enter] to continue.
When selecting TCP/IP Server mode, Portlock Storage Manager will provide you with the IP
address of your server and then listen for a connection from the client side. Please view the Restore
Commands for completing your migration.
Write Image to a Tape Drive
Portlock Storage Manager supports all SCSI tape drives that support writing in Variable Length
Mode. Portlock Storage Manager does not support tape drives that only support block mode. This
is not an issue, as all modern SCSI tape drives support Variable Length Mode. It provides better
tape capacity and higher performance.
58

59. Chapter 7 Image Commands
Portlock Storage Manager writes to a SCSI tape drive using a 32,768-byte block size. This block
size was chosen to maximize performance and tape capacity. Portlock Storage Manager will write
to a tape until the Early Warning of End of Media is detected. A file mark is written to the tape
and the tape is rewound. The cycle repeats itself with a new tape until all data to be imaged has been
written to tape. This allows an image to be spanned across multiple tapes.
Portlock Storage Manager encodes header information while writing to tape. This header information
ensures that data written to tape can be verified when read back. If compression is enabled, additional
information is written to ensure the validity of the uncompressed data.
Write Image to a CD/DVD Recorder
This command allows you to directly image to a DVD recorder. As most servers do not have DVD
recorders installed (in some cases not even a DVD-ROM), a better option may be to image the
server to an FTP server (see next section for details) and
then burn those created images to a DVD or CD to do a file
restore (see Chapter 8 for details on restoration of images
from a disk file).
The DVD image command creates an image of your server on a recordable DVD. If the media is
not formatted then Portlock Storage Manager will format the media and then proceed to write the
image. If the image size exceeds the capacity of the media, you will be asked to remove the existing
media and insert new media so the image can be spanned to accommodate the full image.
Write Image to a FTP Server
Imaging and restoring using a remote FTP server allows network administrators to store and retrieve
images of volumes, partitions and even entire servers. This function is good for backups and for
storing and retrieving images used in a test environment. From the Select Image Destination menu,
select Write image to an FTP server by highlighting it and pressing [Enter].
* See Write Image to a Disk File on page 56 for your Compression and Image File options
NOTE: Some FTP servers are case sensitive for file names.
For example, if a file is “DOS.img,” specifying “dos.img” will
not work.
59

60. Portlock Storage Manager 4.0 for NetWare User’s Guide
You are prompted to enter the IP address, the name of the file that is to be created and the username
and password of the remote FTP server. Portlock Storage Manager will communicate with the server
and start the actual imaging process. It will also simultaneously send the image to the FTP server
to be stored as an image file.
Depending on your user rights on your FTP server, you may be able to send your image to a specific
folder.
Note: Some FTP servers have a default timeout setting
that may need to be configured before you begin the
imaging process. If your timeout setting is not sufficient,
the imaging process may not complete.
Online Imaging
Portlock Online Imaging provides block based imaging for NetWare 6.5 SP3 or later NSS Pools while
they are active with mounted volumes. Portlock Online Imaging depends upon Novell SnapShot
Backup. An NSS Pool, which can be empty, is used by Novell SnapShot Backup to store the deltas
during an image command. Portlock Storage Manager automatically freezes the selected pools,
creates the snapshots, images the pools, thaws the selected pools and finally deletes the snapshots.
Common reasons that Online Imaging fails:
• The Pool is corrupted.
• The Pool holding the snapshot is corrupted.
• The Pool has too many deleted files. Consider purging the volumes within the pool.
• The Pool does not have sufficient free space. Cleanup the volumes within the pool.
• There is too much I/O activity on the Pool. NetWare must duplicate data that is modified
on the pool during an online image. Consider moving some application’s datasets to other
volumes to balance pool I/O.
• There is not enough free space on the pool holding the snapshot.
• There are hardware problems causing I/O errors on either the Pool or the pool holding the
snapshot.
60

61. Chapter 7 Image Commands
NSS Pools Must be in a Stable and Warning-Free State for NetWare’s Snapshot
Feature to Work Correctly
Check your Pool:
• Run “Check Pool” from Portlock Storage Manager.
• This command is located under the “Pool Commands” menu.
• Add the command line option “-logfile=filename”, without the quotes when starting
Portlock Storage Manager.
• Specify the full path to the log file (example: -logfile=C:/STORMGR.LOG).
• You can specify a floppy so that nothing on the server is modified (-logfile=A:/
STORMGR.LOG).
• Do not specify a volume located on a pool that you are “checking” as the log file
would be closed before the full results of the Pool Check could be written.
Verify your Pool:
• Execute Novell’s “nss /poolverify” command from the console. Select the pool to be verified.
See the notes below about log files.
Rebuild your Pool:
• If there are any warnings or errors from the above commands run a “nss /poolrebuild” and
then repeat the check and the verify.
Troubleshooting Pool Errors During an Online Image
• Reboot the server so that everything is in a stable state.
• Consider purging the volumes in the pool. We have seen a number for issues (NetWare bugs)
when there are a lot of “unpurged” files.
• Manually create a snapshot and verify both the original pool and the snapshot pool:
• Assuming that your problem pool is called “SYS” and you have another pool called “TEST”
to store the snapshot, execute the following commands from the NetWare console:
• mm snap list - This will display any snapshots on the server. This should be an empty list
• mm snap create sys test sys_snap - This creates a new snapshot called “SYS_SNAP”,
stores the temporary pool data on pool “TEST”. The original pool is called “SYS”.
Change the names according to your setup.
• mm snap list - Verify that your snapshot was created successfully.
• mm snap activate sys_snap - This activates the snapshot pool called “SYS_SNAP”.
• nss /PoolVerify=SYS - This will verify the active pool “SYS”.
• nss /PoolVerify=SYS_SNAP - This will verify the snapshot of pool “SYS”
• When Portlock Storage Manager is performing an “Online Image” of a pool, SYS_SNAP
is the pool being imaged.

63. Chapter 8 Restore Commands
Introduction to the Restore Commands
The Restore Commands are a subset of commands that allow the user to restore an image previously
created by Portlock Storage Manager’s Image Commands. An image can be restored from a variety
of locations including a Disk File, across a TCP/IP link, a Tape Drive, a CD/DVD, a Web Server
and an FTP Server.
NOTE: The “index.ftp” file is not automatically created. It is a “static” user-created file which
is put on the FTP server. The “index.ftp” file contains comments, remarks and a selectable list of
images. This option is mainly used if you would like to have a lot of different images on the FTP
server but don’t want to remember the names and details of every image. You can put image names
and comments in this file and select them from Portlock Storage Manager. A short example of an
“index.ftp” file is listed below:
• [dos.img] This is an image of a DOS partition
• [diag.img] This is an image of a Diagnostic partition
• [nw4.img] This is an image of a NetWare 4 server
• [nw5.img] This is an image of a NetWare 5 server
• [nw6.img] This is an image of a NetWare 6 server
If you do not wish to create this file, you can use the [F5] key to get a directory listing of your FTP
server and select the file that you wish to restore.
From the Select Image Source menu, choose Read image from a Disk File. This can be a file from
a partition or external device.
63

64. Portlock Storage Manager 4.0 for NetWare User’s Guide
The image can be retrieved from a DOS partition, NetWare volume or a USB disk drive. Enter the
filename of the image file and the source and press [Enter]. In this example, TEST.IMG is being
restored from the SYS volume.
Read Image from a TCP/IP Link
This command will allow you to receive an image sent by either Portlock Storage Manager or
Portlock Image Manager. This command is most commonly used to send a volume or partition
from one system to another across the wire. For example, you have an 8 GB volume you would like
to move from Server A to Server B. One easy way to transfer this volume is to set up Server A in
Image Mode and write that image to TCP/IP and at the same time setup Sever B in restore mode and
read the image from TCP/IP. Using this procedure, the volume would simultaneously be restored on
Server B acting much like a volume copy, except the volume is sent across the wire and the transfer
speed is relatively fast. With 100-Megabit full-duplex Ethernet, transfer speeds of 7 MB per second
are easily achieved.
Note: In the above example, Server A needs to be set to
Server Mode and started first. Server B needs to be set to
Client.
When using the Restore Commands, you should always choose Client from the TCP/IP Mode. The
server side will already be waiting from a connection.
You will be prompted for the IP address of the machine you are imaging after choosing Client from
the restore side. Make sure you have the correct IP address or a connection will not be made and
you will not be able to image and restore.
64

65. Chapter 8 Restore Commands
Once a connection is made, Portlock Storage Manager will provide you with the partition(s) of the
device you are imaging from. When you are ready to begin the restore process, press [Enter] to
continue.
The restore process will begin and may take a few minutes to complete. For this example, we restored
a 10 GB image in 10 minutes.
Once your image has completed, Portlock Storage Manager will provide you a success status and your
partition information. Ensure your drive is bootable to verify the image process was successful.
Read Image from a Tape Drive
This command allows you to restore an image from a tape drive. This is a common use of the image
command as tape drives have been recognized as the most popular media for backup purposes for
many years.
65

66. Portlock Storage Manager 4.0 for NetWare User’s Guide
Read Image from a CD/DVD
This command will allow you to restore an image from a CD/DVD drive. We recommend using the
Portlock Boot CD to boot your system when restoring an image from CD/DVD. Use a portable USB
drive and restore your files from the CD/DVD. This means using two CD/DVD drives – one to boot
from and the other to restore from.
Note: Please see Sending Image to CD/DVD for proper
restore methods.
Read Image from a Web Server
Portlock Storage Manager can read an image from a web server. This allows Portlock Storage
Manager to read a previously created Portlock Storage Manager image from a web server using
HTTP commands and port 80. The Portlock Storage Manager image must be in a directory that an
anonymous user can access. The file does not have to be linked to from a web page, it just needs to
be an unsecured location. This option allows you to have images of your servers available for disaster
recovery, server deployments or test servers.
Portlock Storage Manager can encrypt your image to prevent it from being intercepted during an
image or restore.
Specify the TCP/IP address and image file to retrieve. This will be the address of your web server.
66

67. Chapter 8 Restore Commands
Once a connection is made, Portlock Storage Manager will show you the partition(s) of the .img file
that resides on your web server. When you are ready to begin the restore process, press [Enter].
Portlock Storage Manager allows you to choose which device you wish to restore your image to. Select
your device, confirm you have enough free space and press [Enter] to begin the restore process.
The restore process will take a few minutes to complete. For this example, we restored a 10 GB
image in 10 minutes.
When your image completes, Portlock Storage Manager will provide you a success status and your
partition information. Ensure your drive is bootable to verify the image process was successful.
Read Image from an FTP Server
Portlock Storage Manager supports using FTP servers for both imaging to and restoring from. This
includes NAS devices that support the FTP. Create a disaster recovery image of your server and save it
to an FTP server. Retrieve and install this image using FTP or HTTP onto a bare-metal machine.
67

68. Portlock Storage Manager 4.0 for NetWare User’s Guide
Enter the username and password of your FTP server. If your login credentials are incorrect, you
will be unable to retrieve the .img file from your server. You may press F5 for a directory listing on
your FTP server, providing you have the correct username and password.
* See Write Image to a Disk File on page 56 for your Compression and Image File options
After a connection is made, Portlock Storage Manager will display the partition(s) from your .img
file that will be restored to your system. Press [Enter] to continue.
Portlock Storage Manager will ask you which device you wish to restore your image to. Select your
device, verify it has enough free space and press [Enter] to begin the restore process.
68

69. Chapter 8 Restore Commands
The restore process will begin and may take a few minutes to complete. For this example, we restored
a 10 GB image in 10 minutes.

71. Chapter 9 Repair Commands
Introduction to the Repair Commands
The Repair Commands in Portlock Storage Manager are invaluable. These commands have been
designed to automatically find and restore deleted partitions and volumes and provide additional
data recovery tools.
Create a Sector Image of a Disk Drive Command
The Create a Sector Image of a Disk Drive Command is used to make an exact image of an attached
disk drive. Instead of imaging and restoring a server at the partition/volume level, this command
makes it possible to create and restore an exact 1:1 bit-for- bit image of a selected disk drive. This
command is commonly used to make backups of failing disk drives while upgrading from smaller to
larger drives. These “sector images” can be imaged and restored from a variety of devices, including
hard disks, across a TCP/IP link, tape drives, CD/DVDs, Web servers and FTP servers.
Portlock Storage Manager will prompt you with a message stating this command is intended for
data recovery operation and not for duplicating drives as most modern operating systems embed
information into the partitions that must be modified for correct drive cloning.
71

72. Portlock Storage Manager 4.0 for NetWare User’s Guide
Portlock Storage Manager will ask you to select the device for the sector image to be written to.
Fix Master Boot Record (MBR)
If the sectors in your MBR have been manipulated for any reason, Portlock Storage Manager will
correct the MBR with the operating system that was selected.
Portlock Storage Manager will prompt you that the MBR has been repaired.
If you accidentally delete a DOS partition, Portlock Storage Manager will allow you to recover the
partition as long as no other partitions have overwritten it.
It is recommended that a sector copy of the disk drive that contains the deleted partition be made
prior to attempting a partition recovery. Depending on how many disk drives you have, this may
take awhile.
If Portlock Storage Manager is able to find a partition that is recoverable, the size of the partition and
the device it belongs to are displayed. Select this partition and hit [Enter] to recover the partition.
72

73. Chapter 9 Repair Commands
The DOS partition has been successfully recovered and returned to its original location.
NetWare Traditional Partition and Volume Recovery Commands
Portlock Storage Manager provides you with another list of options to choose from. Choose the
option that best suits your needs.
For NetWare 6 Master partitions, sub partitions and Traditional volumes, the process is the same.
If Portlock Storage Manager sees a partition, you will have the ability to recover it. If you have
overwritten your deleted partition, there will be no chance to recover your partition.
Portlock Storage Manager detects a deleted sub partition and allows you to restore your partition
to its original location.
A NetWare 6 Master Partition was successfully recovered.
73

74. Portlock Storage Manager 4.0 for NetWare User’s Guide
Copy a Corrupted Volume to a New Volume
Note: This command is only intended for Traditional
Volumes.
Repair a Volume with a Missing Volume Segment
Note: This command is only intended for Traditional
Volumes.
Backup FAT Tables to a Disk File
74

75. Chapter 9 Repair Commands
NetWare NSS Partition and Volume Recovery Commands
Portlock Storage Manager provides you with a list of options for recovering and repairing NSS
partitions and volumes.
Recovering a NetWare 6 Master and Sub partition is the same procedure as recovering a traditional
partition. If Portlock Storage Manager detects your deleted partition, you will have the ability to
recover it.
Rebuild a Pool’s Free Tree
Portlock Storage Manager will provide you with a list off NSS pools to choose from to rebuild your
free tree. Select the tree you wish to rebuild and press [Enter].
Portlock Storage Manager will perform a pool check on your selected pool and rebuild your free
tree.
75

76. Portlock Storage Manager 4.0 for NetWare User’s Guide
VMware Partition and Volume Recovery Commands
For virtualization, Portlock Storage Manager detects if the boot code in sector 0 exists. Virtual disks
created by virtual software programs appear to be correct in regards to sector 0 (MBR) but they
actually do not have any boot code. Storage Manager will install the correct boot code (if necessary)
to prevent future problems with your system.
NOTE: This command will only work with VMFS
partitions.

Portlock Storage Manger will list your system’s PCI devices.
The last feature displayed is generally used for virtual environments only. This will install the VMware
SCSI driver (vmscsi.sys) to your OS.
Select the source for editing the Windows registry. For this example, we will select a physical disk
partition.
In this example, our VMware server has two devices to choose from to install the VMware SCSI driver.
However, only one of them has a partition. If nothing resides on your device it will be impossible
to install the driver.
You have successfully installed the VMware SCSI driver to your device.

The System Commands can open and close log files that can be used by Portlock Technical Support
to troubleshoot customer issues. The user can manually rescan for drives and partitions, as well as
send and receive various files from other instances of Portlock Storage Manager and Portlock Image
Manager.
Although Portlock Storage Manager rescans drives and partitions by default after most operations,
the System Menu will allow you to do so at anytime.
Open Logfile
This command opens a user-defined log file for Portlock Storage Manager.
To open your log file, specify the path of the created log file in the dialog box and press [Enter]. If
you specified the correct path, you will be notified that the log file has been opened.
80

Close Logfile
To close the log file, choose Close Logfile from the System Menu and press [Enter].
Recv File
This command will allow the user to receive a file sent from either Portlock Storage Manager or
Portlock Image Manager. It is useful for transferring images across the wire via TCP/IP.
Specify the path that you wish the file(s) be written to. For help, follow the examples below.
Send File
Send File allows the user to send a file to another instance of Portlock Storage Manager or Portlock
Image Manager. Portlock Image Manager receives an image and simultaneously writes the image
to a remote tape drive. Switch to remote mode to have Portlock Remote control Portlock Storage
Manager remotely. See the Appendices for Portlock Remote for details.
81

82. Portlock Storage Manager 4.0 for NetWare User’s Guide
Specify the path of the file or press Insert to select a file and press [Enter].
Portlock Storage Manager takes you through the same steps as if you were imaging over TCP/IP. You
will choose Server Mode from the sending side and Client Mode from the receiving side.
The server side waits for a connection until you have input the IP address of the server you are
sending the image from on the client side. The send and receive process will begin.
Disk Format
Portlock Storage Manager allows you to format a disk from the System Commands. Use caution
with this command as this will remove all data from your disk.
Portlock Storage Manager will display all of the devices in your system. Choose the one that you
wish to format and press enter.

Appendix A
Automated Imaging with the use of CRON.NLM
CRON.NLM can schedule Portlock Storage Manager specified dates and times. CRON.
NLM reads an ASCII text file called “CRONTAB” that you create in the SYS:ETC directory.
The CRONTAB file tells the CRON.NLM when to run a NetWare console process, such as
a NetWare *.NCF Batch file. The formatting for CRONTAB and the CRON.NLM can be
obtained below.
FILES: CRON.NLM, CRON.MSG, NCSCRIPT.NLM, COPY.NLM
NCSCRIPT.NLM – http://www.novell.com/coolsolutions/tools/1169.html
CRON.NLM & CRON.MSG (cron5.exe)
http://support.novell.com/cgi-bin/search/searchtid.cgi?/2939440.htm
COPY.NLM – http://www.netwarefiles.com
Results: The CRON.NLM will run the .NCF file at your scheduled time. The COPY.NLM
will copy the NCSCRIPT job file, just before NCSCRIPT loads.
NOTE: It’s recommended to obtain all of these files from
the following URLs and save them to a floppy before
beginning. Be sure to unzip your files before adding them
to your floppy. Your CRON.NLM and CRON.MSG are inside
of your cron5.exe file.
NOTE: Be careful about capital letters and spacing when
naming files and scripts. CRON is case sensitive to your
files.
86

87. Appendix A Automated Imaging with the use of CRON.NLM
Setup
1. Copy and Paste NCSCRIPT.NLM into the SYS:SYSTEM directory
2. Type “Load NCSCRIPT” in the system console once and then unload
a. This creates the SYS:DISTRIB directory. Unload NCSCRIPT and refresh your SYS
directory.
3. Create your stormgr file in SYS:DISTRIB directorya. This is where you will put the
path to load PSM. Right-click on the file and click edit file to add path directions
b. Example: load sys:/stormgr/stormgr
4. Copy and paste COPY.NLM into the SYS:SYSTEM directory
5. Type “LOAD CRON.NLM” (without the quotations) in the autoexec.ncf of your file server,
located in SYS:SYSTEM with the rest of the LOAD .NLM files.
6. Copy and paste CRON.NLM to the SYS:SYSTEM
7. Create a file named crontab in the SYS:ETC
a. This is where you will put your CRON schedule
b. Example: 00 21 * * * stormgr.ncf
c. Also make sure this is where you put your .ncf file which is part of your script.
8. Type “Load CRON” in your system console
87

88. Portlock Storage Manager 4.0 for NetWare User’s Guide
9. Create a .ncf file in your SYS:SYSTEM
a. Example: stormgr.ncf
b. This is the file you will run from the crontab file
You will need to implement the following commands into this .ncf file by right-clicking on it
and selecting edit file.
NOTE: COPY.NLM is used to copy the file stormgr that
you created from SYS:DISTRIB to the SYS:DISTRIBJOB
directory just to run the file, this does not actually make a
hard copy of the file.
NOTE: Loading CRON will also create a CRON.LOG, which
shows when your schedule has been run and if it has been
run successfully.
#STORMGR.NCF BEGIN

#STORMGR.NCF END
EXPLANATION
UNLOAD COPY.NLM
# This uses the COPY.NLM to copy the file called stormgr (or the file that you created)
# to NCSCRIPT’s # incoming job queue UNLOAD NCSCRIPT.NLM
# This unloads the NCSCRIPT.NLM if it’s already loaded
# There are no errors when this NCF tries to load it again LOAD COPY SYS:DISTRIB
STORMGR SYS:DISTRIBJOBSTORMGR
# This uses the COPY.NLM to copy the file called stormgr (or the file you created) to the JOB
folder
# To NCSCRIPT’S # incoming job queue
88

89. Appendix A Automated Imaging with the use of CRON.NLM
? UNLOAD COPY.NLM
# This unloads COPY.NLM, AFTER A 10-SECOND WAIT.
# The question mark tells the OS to Pause for 10 sec LOAD NCSCRIPT /NOPURGE
# This loads NCSCRIPT and tells NCSCRIPT not to purge its JOB queue, which NCSCRIPT
usually does on startup. NCSCRIPT Will first process the stormgr script and then it will purge
the stormgr file.
10. Copy the Paste the CRON.MSG file in the SYS:/SYSTEM/NLS/4 and in the SYS:SYSTEM
directory
11. Now in the Crontab that you created in the SYS:/ETC you will need to set your schedule to run
your file that you created (stormgr.ncf).
Each entry is checked in turn, and any entry matching the current time is executed.
The entry * matches anything. A pound sign (#) is a comment. Valid values are:
Minute (0-59)
Hour (0-23)
Day-Of-Month (1-31)
Month (1-12)
Day-Of-Week (0-6) Note: week starts with 0=Sunday
EXAMPLES: (schedules are all in military time)
#Min Hr Dat Mo Day Command
#run time every minute
* * * * * time stormgr.ncf
#Run stormgr.ncf on the hour
0 * * * * stormgr.ncf
#Do backup Mon-Fri at 4:30
30 16 * * 1-5 stormgr.ncf
#Do backup on Friday night at 11:00pm
00 23 * * 5 stormgr.ncf
#3:17 everyday run stormgr.ncf
17 15 * * * stormgr.ncf
NOTE: The CRON.NLM will run the stormgr.ncf file at your
scheduled time. The COPY.NLM will copy the NCSCRIPT
job file, just before NCSCRIPT loads. This doesn’t actually
create a hard copy, but rather places it into the job file for
it to load and then erases it from the job file.

Portlock Storage Manager and NSS Snapshots
Online Imaging, Backup and Restore
The following discusses Portlock Storage Manager’s advanced support for NSS Snapshots,
providing the ability to image mounted (online) and unmounted (offline) NSS Pools.
Introduction
From administrators of single-server networks to giant server farms, one of the most often requested
improvements in the storage management arena is the ability to recover a failed volume, pool, partition
or entire computer hard drive as quickly and transparently as possible.
Portlock Storage Manager can create, activate, delete, etc. NSS Pool Snapshots is of great potential
value to NetWare customers. Falling disk prices have enabled imaged-based disk backups to be as
inexpensive as tape, as well as faster and much more convenient. Days spent searching through
backup tape index listings for an accidentally deleted file can now give way to a quick volume search
and restoration.
Snapshot support in Portlock Storage Manager makes software-based backup and recovery operations
incredibly easy and non-intrusive to end users. Portlock Storage Manager enables the creation of
multiple Read/Write point-in-time copies of NSS Pools, and can retain these copies independently
from the original pool.
NOTE: This feature is only supported on NetWare 6.5 SP3
and later versions.
Online Imaging and NSS Snapshots
Online Imaging and NSS Snapshots feature creates images of snapshots that can be used to make

Scripting Support in Portlock Storage Manager
We have added several command line options to automate scripting.
1. You want to image your workstation or server to an FTP server:
stormgr -script -os=6 -imageall -
imageftp=192.168.1.10,anonymous,user@test.com,imgfile.img
2. You have mapped a drive letter from DOS using either the Novell Client or the Microsoft
Client. You want to image your workstation or server to this mapped drive letter.
stormgr -script -os=6 -imageall -imagefile=g:imgfile.img -purge
3. You want to image your NetWare 6.5 server using Online Imaging to an FTP server.
stormgr -script -online -imageall -
imageftp=192.168.1.10,anonymous,user@test.com,imgfile.img
Details:
-script Turn on scripting.
-os=6 Set the version for NetWare emulation (3, 4, 5, 6 or 65).
For Windows workstations, set to 6
-imageall Image all disk drives and all partitions/volumes
-imageftp=ip_address,ftp_user,ftp_password,filename

What is NSS Snapshotting?
Note: The NSS Snapshot feature is only available on NetWare 6.5. In addition, this is not the same
as Novell ZENworks’ snapshot feature, which is an application cloner/installer.
A pool snapshot is a metadata copy of a storage data pool. The snap preserves a point-in- time view
of a data pool, and supports data backup and recovery for that pool. You can create, manage and
delete a pool snapshot for any pool on your server. You can take a snapshot and activate it later to
access the original pool’s data as it existed at the time of the snapshot. Both the pool and its snapshots
can be active and available concurrently. You can access data on the active pool snapshot just as
you would any other pool, even while data is changing on the original pool. Exercise caution when
using this feature, because its implementation will cause server performance to decrease. A pool
snapshot facilitates non-disruptive backups because the snapshot becomes the source of the backup.
As contrasted to a traditional, full-data copy of the pool, the metadata copy only takes a moment to
create and occurs transparently to the user.
With traditional backups, applications might be shut down throughout the backup routine.
In comparison, the pool snapshot process makes the original pool available with almost imperceptible
delay.
The pool snapshot function uses copy-on-write technology to enable the instantaneous block-level
snapshot of a pool and requires only a fraction of the storage space of the original data pool. A pool
snapshot does not save an exact copy of the original data pool. Instead, the snapshot is a metadata-
based copy that stores only the blocks of data that change subsequent to the instant of the snap. The
snapshot combines the metadata and stored block data with the unchanged data on the original pool
to provide a virtual image of an exact copy of the data at the instant the snapshot was taken, plus
any end-user modifications made to that snapshot.
92

93. Appendix B Portlock Storage Manager and NSS Snapshots
Benefits of Pool Snapshots
Pool snapshots save time and preserve data. They provide an instant copy of a pool that can help
expedite routine maintenance procedures to back up, archive and protect data on that pool. Because
traditional methods of duplicating large amounts of data can be expensive and time consuming, the
efficiency of snapshots can be an important benefit for your enterprise. You can make snapshots as
frequently as needed to meet your data availability and resilience requirements. You can use pool
snapshots in a variety of ways to enhance your current storage infrastructure, including the following
scenarios:
Supporting Backup Operations
A pool snapshot facilitates non-disruptive backups because the snapshot becomes the source of the
backup. As contrasted to a traditional, full-data copy of the pool, the metadata copy only takes a
moment to create and occurs transparently to the user. With traditional backups, applications might
be shut down throughout the backup routine. In comparison, the pool snapshot process makes the
original pool available with almost imperceptible delay.
Archiving and Restoring Data
Administrators can archive pool snapshots to capture a history of the changes made to the original
data pool. Pool snapshots can be used as a source for restoring information. Two common reasons
to restore information are user error and application errors.
A user might inadvertently make changes to a file which needs to be reversed. Files can become
corrupted or deleted. The pool snapshot provides a quick and easy way to locate and reinstate
selected files.
An application might be infected by a virus or be corrupted by other problems, causing the application
to store erroneous data throughout the pool. With a pool snapshot, you can rollback all or part of the
original pool to a point in time before the virus or problem was known to exist in the system.
Re-Creating Operational and Development Environments
You can write to the pool snapshot just as you would to any pool. You can work with and modify
the snapshot version of the data. For example, in a development environment, the engineers might
want to repeat builds and tests of data in a particular snap. Snapshots can also provide a convenient
source for data mining, as well as testing and training environments.
93

94. Portlock Storage Manager 4.0 for NetWare User’s Guide
How to Enable Snapshots
Novell interfaces into the NSS via the “_ADMIN” volume with NetWare 6.5 to flush and freeze a file
system prior to taking a snapshot. This interface takes XML-formatted requests, which specify the
pool name, a timeout and a hold timer. When requests are submitted, they are assigned keys that are
unique to the given request. When queried with this key, the interface will return an XML-formatted
response that includes the freeze status and other information.
The simplest way to automate the freeze/snap/thaw process is to make use of the PERL interpreter
included with NetWare. As a language, PERL easily handles string manipulation and parsing. In
addition, the open-source and business communities have contributed hundreds of modules that can
be used to extend the capabilities of PERL without significant development effort. A standard set
of modules ship with NetWare 6.5 SP3/Open Enterprise Server.
Before the snapshot can occur, the snapshot function must render the original pool quiescent by
briefly halting data transaction activity when current transactions complete. It temporarily prevents
new writes to the pool and flushes the file system cache to make the pool current with existing writes.
Open files are seen by the snapshot feature as being closed after these outstanding writes occur. Then,
it snaps the now-stable pool and allows data transaction activity to resume.
The quiescence process provides a consistent image at the instant the snapshot is made. Because
the snapshot is consistent, it is not necessary to check the consistency of the file system or database
when you activate the snapshot for access. After the snap, the snapshot function continues to track
transaction activity in the original pool. It determines which blocks in the original pool will change
as data writes are made to the original pool. It suspends write activity while it copies the original
block data to the designated pool where it stores the pool snapshot, referred to as the “stored-on
pool.” Then it allows a write to that block in the original pool. This keeps the snapshot metadata
consistent in time with the exact instant the snapshot was taken. As the original pool changes, the
snapshot can grow to the size of the stored-on pool.
The average disk space requirements for a pool snapshot are 10 percent to 20 percent of the original
pool size. The actual space depends on how many writes are made to the original volume and the
time period that the snapshot exists before it is archived or deleted. Currently, a combination of up
to 500 snapshots can exist on any given stored-on pool. Remember that the more snapshots you must
traverse to find data, the longer it takes to retrieve the data, and the slower the perceived response
time to the user.
Activating NSS Snapshots
Although the pool snapshot feature is inactive by default, the snapshot functions are working in the
background to capture any changes being made to the original pool. For pool snapshots, Inactive
and Active are conditions related to the visibility of the pool snapshot to users as a pool. Active pool
snapshots are online; inactive pool snapshots are offline.
94

95. Appendix B Portlock Storage Manager and NSS Snapshots
You activate a pool snapshot when you want to access the data on it, such as for data retrieval, data
modification and data backup. After the pool snapshot is active, it appears by its user-assigned
snapshot name in the pool list. Treat it as you would any pool to manage the pool and to activate
and mount its volumes.
The names of volumes on the pool snapshot are a modified version of the volumes on the original
pool. Generally, a “_SV” (snapshot volume) is added to the volume name. When you deactivate the
pool snapshot, any snapshot volumes on it are automatically deactivated and its snapshot name is
no longer listed in the pool list.
Mounting a NetWare NSS Pool Snapshot
1. Take a snapshot
Define a subdisk on one storage LUN which will be used to hold the snapshot. Create the
snapshot and activate it. At this point, you will have captured the “point in time” state of your
target volume which will remain intact until the snapshot is deactivated or deleted.
2. Expose the snapshot
When you are ready to use the snapshot for a backup session or file recovery, expose it on a new
target. Do not expose it on a target that is already connected to the NetWare server.
3. Mount the snapshot onto the backup server
If the NetWare backup server also contains the original volume (pool) then it is necessary to
rename the original pool before mounting the snapshot volume. This can be done in Remote
Manager simply by selecting the appropriate “pool” link from the Partition Disks menu. The
option to rename the pool will appear.
Once the pool is renamed, connect to the target on which the snapshot resides (through the iSCSI
services menu in Remote Manager). Once connected, the volume should appear as a complete
device/partition/pool/volume scheme in the Partition Disks menu.
Select “Mount Volume” from the menu.
4. Run the backup
If you are doing a simple file recovery, you can copy the lost files back to your original volume
directly. If you are running a backup, run your backup routine on the snapshot volume as though
it’s a full, active volume. If you want to separate the backup IP server traffic from the production
IP traffic, you can simply put the backup server onto a different subnet. The storage side will still
be sharing the traffic load between the production servers and the backup server, but its effect
on performance should be negligible.
95

96. Portlock Storage Manager 4.0 for NetWare User’s Guide
NOTE: Mounting a snapshot on a NetWare server which
contains the target pool requires that the pool be renamed
so the server does not contain two active volumes with
the same pool name.
5. Unmount the snapshot volume
When the backup is complete, unmount the snapshot volume in NetWare and disconnect from
the target. Rename the original pool back to its original name, if desired. Delete or deactivate
the snapshot.
NOTE: Novell Storage Services enables snapshot
file services for backup and versioning of enterprise
applications running on NetWare 6.5, even when files
are open. For example, a GroupWise application opens a
database and is always running during the nightly backup.
NSS can keep an original backup of the database when that
file was last closed. While the backup is running, NSS will
backup the open file as well as the original copy.

ATA: Supports 1 or 2 hard drives, a 16-bit interface and PIO modes 0, 1 and 2. Also known as
IDE.
ATA-2: Supports faster PIO modes (3 and 4) and multiword DMA modes (1 and 2). Also supports
logical block addressing (LBA) and block transfers. ATA-2 is marketed as
Fast ATA and Enhanced IDE (EIDE).
BIOS (Basic Input Output System): The BIOS is built-in software that determines what a
computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code
required to control the keyboard, display screen, disk drives, serial communications, and a number
of miscellaneous functions.
Disk: A round plate on which data can be encoded. There are two basic types: magnetic and optical
disks.
EIDE (Enhanced Integrated Drive Electronics): A newer version of the IDE mass storage device
interface standard developed by Western Digital Corporation. It supports data rates of between
4 and 16.6 MB/s, about three to four times faster than the old IDE standard. It can support mass
storage devices of up to 8.4 gigabytes, whereas the old standard was limited to 528 MB. Because of
its lower cost, enhanced EIDE has replaced SCSI in many areas. EIDE is sometimes referred to as
Fast ATA or Fast IDE, which is essentially the same standard, developed and promoted by Seagate
Technologies. It is also sometimes called ATA-2.
FAT (File Allocation Table): File systems used by DOS, DR-DOS, PC-DOS, and Windows to store
user files and directories.
FAT-12: A version of the DOS FAT that uses twelve-bit numbers to store disk block addresses.
FAT-16: A version of the DOS FAT that uses sixteen-bit numbers to store disk block addresses.
FAT-32: A version of the DOS FAT that uses thirty-two-bit numbers to store disk block addresses.
GB (Gigabyte): A GB is 1,073,741,824 bytes. However, most disk drive companies use 1,000,000,000
as a GB when referring to disk drive capacity.
HotFix: HotFixing of disk sectors prevents data from being stored in a bad sector or cluster.During a
HotFix, the operating system automatically detects bad disk sectors, relocates the data to a safe cluster
and marks the bad cluster as unusable to the system. This process is transparent to the user, requires
no interaction on the user’s part and does not report any error messages to any applications.
IDE (Integrated Drive Electronics): An IDE interface is an interface for mass storage devices, in
which the controller is integrated into the disk or CD-ROM drive.
98

99. Glossary
Image: A method of converting the contents of a hard drive — including its configuration settings
and applications into an image, and then storing the image on a server or burning it onto a CD or
another device.
Input/Output (I/O): The term I/O is used to describe any program, operation or device that transfers
data to or from a computer and to or from a peripheral device. Every transfer is an output from one
device and an input into another. Devices such as keyboards and mouses are input-only devices
while devices such as printers are output-only. A writable CDROM is both an input and an output
device.
Logical Block Addressing (LBA): A method used with SCSI and IDE disk drives to translate the
cylinder, head, and sector specifications of the drive into addresses that can be used by an enhanced
BIOS.
LBA is used with drives larger than 528 MB.
Master: Refers to an architecture in which one device (the master) controls one or more other
devices.
MB (Megabyte): A MB is 1,048,576 bytes. Most disk drive companies use 1,000,000 as a MB when
referring to disk drive capacity.
NetWare: A popular local area network (LAN) operating system developed by Novell. NetWare is
a software product that runs on a variety of different types of LANs, from Ethernets to IBM token-
ring networks. It provides users and programmers with a consistent interface that is independent of
the actual hardware used to transmit messages.
NetWare Partition: A NetWare Partition is an area of a disk drive that stores NetWare volumes.
A NetWare partition contains three data areas: 1) System Area, HotFix Data Area, and the Data
Area. The System Area contains information about the size of the partition. The HotFix Data Area
contains information about redirected data blocks. The Data Area contains NetWare volumes. A
NetWare Partition can contain eight NetWare volume segments. A NetWare volume can consist of
one to thirty-two volume segments.
Novell’s Definition: A partition created on each network hard disk, from which NetWare volumes
are created.
NetWare Volume: A NetWare volume is a file system that contains user files and data. A NetWare
volume can consist of one to thirty-two NetWare volume segments.
Novell’s Definition: A fixed amount of physical hard disk storage space. A NetWare volume is
the highest level in the NetWare file system directory structure.
99

100. Portlock Storage Manager 4.0 for NetWare User’s Guide
NetWare Volume Segment:
Novell’s Definition: A physical division of a volume. A volume can span up to 32 disk drives.
If more than one drive, each drive in the volume is a volume segment.
NSS (Novell Storage Services):
Novell’s Definition: A high-performance, 64-bit storage and access system that supports very
large files as well as large numbers of files and NSS volumes. NSS runs with the traditional
NetWare file system in NetWare. NSS installs on the server as a set of NLM programs. NSS also
runs on Open Enterprise Server running a SUSE LINUX Enterprise Server kernel.
NSS Admin Volume:
Novell’s Definition: In NSS, a read-only volume that is automatically created when a storage
group and NSS volume are created. This volume contains a dynamic list of objects that NSS
uses, and cannot be deleted.
NSS Type 0 Partition: A NetWare Partition without the HotFix Data Area. This partition is not
used for NSS volumes, it is used for NetWare volumes that cannot be Mirrored or support HotFix
Data Areas.
NSS Type 1 Partition: An NSS Type 1 Partition is a Partition that contains one NSS volume. This
is basically the first level of NSS partitions. The NSS volume must be the same size as the partition.
This partition cannot be mirrored or support HotFix Data Areas. Portlock Storage Manager supports
converting an NSS Type1 partition with a volume into a Storage Group.
NSS Type 2 Partition: An NSS Type 2 partition is an NSS Storage Group that can contain one or
more volumes. With Novell supplied tools, you first create an NSS partition and then convert it into
an NSS Storage Group. Then you can add volumes to the Storage Group.
NSS Storage Group (See NSS Type 2 Partition)
Novell’s Definition: A pool of storage free space representing logical space owned by NSS.
Once space is claimed by NSS, the free space becomes a managed object that can be divided
into other storage groups and NSS volumes.
Partition: A partition is a contiguous region of a disk drive used to store data.
Primary Partition: A primary partition contains a single volume that is the size of the partition.
Read-Only Sequential Verify: This method performs a read-only sequential scan of the disk drive.
Various block sizes are supported from 1 sector to 512 sectors per I/O. No data is written to the drive.
This method is also a quick method to determine the read performance of a disk drive.

Read-Only Random Verify: This method performs a read-only random scan of the disk drive. The
software generates a random number which determines the sector to read. Various block sizes are
supported from 1 sector to 512 sectors per I/O. No data is written to the drive. This method is quick
in determining the random I/O performance of a disk drive.
Read-Write Sequential Verify: This method verifies that data can be written to a disk drive and
then read back. A data pattern that is unique to each sector is written to the disk and then compared
on read back. Various block sizes are supported from 1 to 512 sectors per I/O. For this verify mode,
an option is to perform an extensive verify, which writes multiple data patterns to the disk drive.
This includes performing a bit-walk data pattern to detect missing sector bits. Data is written to the
drive, which will destroy all partitions, volumes, and data on the disk drive.
