The IBM Storwize V7000 Unified system includes the IBM Storwize V7000 file module and the Storwize V7000 storage system. The IBM Storwize V7000 Unified system supports both block and file protocols. Network Data Management Protocol (NDMP) is an open protocol for managing data stored on networked servers. The NDMP future development is under the direction of the Storage Networking Industry Association (SNIA), which has a work group for NDMP.Executive summaryEMC NetWorker is a suite of enterprise-level data protection software that unifies and automates backupto tape, disk-based, and flash-based storage media across physical and virtual environments for granularand disaster recovery. EMC NetWorker also supports a wide range of data protection options includingNDMP support.The IBM® Storwize® V7000 Unified system supports NDMP version 4. The NDMP function is configuredand managed on the Storwize V7000 Unified system using the Storwize V7000 Unified graphical userinterface (GUI) or command-line interface (CLI) from the active management node. NDMP alerts arewritten to the alert log on the Storwize V7000 Unified active management node.This technical report provides details on configuring the NDMP feature of IBM Storwize V7000 Unifiedsystem and enabling EMC NetWorker NDMP-specific settings and functionality.Intended audienceThis technical report is intended for: • Customers and prospects looking to implement effective NDMP backup solution on IBM Storwize V7000 using the EMC NetWorker software • Users and management seeking detailed information to implement NDMP backup solution on the IBM Storwize V7000 Unified system using the EMC NetWorker software.ScopeThis technical report provides: • Detailed NDMP backup solution implementation on the IBM Storwize V7000 Unified system with EMC NetWorker • Detailed NDMP backup implementation guide and configuration best practicesThis technical report does not: • Discuss any performance impact and analysis from a user perspective • Replace any official manuals and documents from IBM and EMC NetWorker on the products used in the NDMP backup solution Implementing an NDMP backup solution using EMC NetWorker on IBM Storwize V7000 Unified system 1
  • 5. PrerequisitesThis technical paper assumes familiarity with the following prerequisites: • Basic knowledge of the IBM Storwize V7000 Unified system • Basic knowledge of EMC NetWorker • Availability of the Storwize V7000 file module software version 1.3 GA or higher in the IBM Storwize V7000 Unified system.IBM Storwize V7000 Unified system overviewThe IBM Storwize Unified system is a virtualized storage system (to complement virtualized serverenvironments) that provides unmatched performance, availability, advanced functions, and highly-scalablecapacity hardly seen in earlier midrange disk systems. This powerful midrange disk system has beendesigned to be easy to use and enable rapid deployment without additional resources. The StorwizeV7000 Unified system consolidates block and file workloads into a single storage system for simplicity ofmanagement and reduced cost, and offers greater efficiency and flexibility through built-in solid-state drive(SSD) optimization and thin-provisioning technologies. The advanced functions of this storage system alsoenable nondisruptive migration of data from existing storage, simplifying implementation and minimizingimpact to users. The Storwize V7000 Unified system enables you to virtualize and reuse existing disksystems, supporting a greater potential return on investment (ROI). The system includes IBM Active CloudEngine™, which is designed to deliver policy-based management of files to reduce costs through use oftiered storage and improve data governance.The IBM Storwize V7000 Unified system includes two file modules and the IBM Storwize V7000 storagesystem, and is designed to support both, file as well as block protocols. Figure 1 shows a pictorialrepresentation of the IBM Storwize V7000 Unified system. The file module is a clustered systemcomprising two enclosures that provide file systems for use by network-attached storage (NAS). The filemodule uses the Storwize V7000 storage system to provide the file module with volumes. Volumes arealso provided on the storage area network (SAN).The Storwize V7000 storage system consists of a control enclosure that contains disk drives and two nodecanisters that are managed as a single clustered system. Both, hard disk drives (HDDs) and SSDs aresupported. Expansion enclosures contain drives and are attached to the control enclosure. Expansioncanisters include the serial-attached SCSI (SAS) interface hardware that enables the node hardware touse the drives of the expansion enclosures.The IBM Storwize V7000 file module software within the Storwize V7000 Unified system contains theinterface node, storage node, and management node functions. A management node is used forconfiguring, administering, and monitoring a system. An interface node connects a system to an InternetProtocol (IP) network using following protocols. • Common Internet File System (CIFS) • Network File System (NFS) • File Transfer Protocol (FTP) • Hypertext Transfer Protocol Secure (HTTPS) • Secure Copy Protocol (SCP) Implementing an NDMP backup solution using EMC NetWorker on IBM Storwize V7000 Unified system 2

The file module of the Storwize V7000 Unifiedsystem supports NDMP version 4.The Storwize V7000 Unified system NDMP implementation provides the capability to back up and restorethe file systems of the Storwize V7000 Unified system. The granularity of backup is at the directory level.NDMP supports the concept of a full backup and an incremental backup. A full backup copies all files anddirectories specified to be backed by NDMP. An incremental backup copies the files that have changedsince the last successful incremental or full backup. In the event no previous backup has been finished, allthe files are backed up. Incremental backups occur automatically according to the scheduled criteria. Acomplete restore requires the last full backup and all incremental backups that have occurred since thelast full backup.Storwize V7000 Unified system NDMP supported physical configurationThere are two primary methods in which NDMP can be used as an interface with the Storwize V7000Unified system. • Two-way (or remote) NDMP • Three-way NDMPThe following sections describe the two-way (or remote) and three-way NDMP configurations in detail. Two-way (or remote) NDMP configuration The two-way NDMP configuration consists of an external data management application, such as EMC NetWorker, running on a server external to the Storwize V7000 Unified system. The data management application has some form of storage hierarchy, such as a tape library or a tier 2 disk storage that it manages for the storage of backup data. In addition to the external data management application (EMC NetWorker), an Ethernet network exists. This Ethernet network connects the data management application to the Storwize V7000 Unified system file modules on which the NDMP server is running. NDMP controls the information and data traffic across the network between the external DMA and the Storwize V7000 Unified system file modules on which the NDMP server is running. The recommendation is to have a high-speed 10-Gb Ethernet network to handle the volume of data being backed up or restored.

  • 8. Figure 2 shows an example of a two-way NDMP configuration. It includes an external data management application (EMC NetWorker) running on a server external to the Storwize V7000 Unified system. The data management application is connected to an 8-Gbps Fibre Channel (FC) SAN along with an IBM System Storage® TS3200 tape library with some FC attached tape drives, such as IBM Linear Tape-Open data cartridges, Generation 3, Generation 4, or Generation 5 tape drives. The data management application is connected to a 10-Gbps Ethernet network to which the Storwize V7000 Unified system file modules are attached. In Figure 2, the lines are intended to show the type and speed on the connections between the various physical components and do not necessarily represent the actual number of physical links.Figure 2: Two-way NDMP backup configuration Three-way NDMP configuration In a three-way NDMP implementation, an NDMP tape server is installed on a server external to the Storwize V7000 Unified system and separate from the server on which the EMC NetWorker data management application is running. Some form of storage devices, such as a virtual tape library or real tape library and tape drives are attached to the server running the NDMP tape server. The NDMP controls the traffic flows between the EMC NetWorker data management application and the Storwize V7000 Unified system file modules. NDMP data traffic (the actual data being backed up or restored) flows between the Storwize V7000 Unified system file modules and the NDMP tape server. Therefore, it is recommended that the Ethernet network between the NDMP tape server and the Storwize V7000 Unified system file modules running the NDMP server be a high-speed 10-Gbps Ethernet network. Figure 3 shows an example of an NDMP three-way configuration. In this example, the Storwize V7000 Unified system file modules used for NDMP backup and restore are on a 10-Gbps Ethernet network along with the NDMP tape server. The server on which the NDMP tape server is running is connected Implementing an NDMP backup solution using EMC NetWorker on IBM Storwize V7000 Unified system 5

There is a provision to configure a set of file modules that will be part of an NDMP_NODE_GROUP. This set of file modules is paired with network group IP addresses that can be assigned to a specific network port. This network port is associated with the NDMP service. • The NDMP server running on the file modules provides both data and control connections to servers external to the Storwize V7000 Unified system on which a data management appliance is running. • The ability to configure the NDMP parameters for this set of file modules (the NDMP_NODE_GROUP) is provided through the Storwize V7000 Unified system CLI commands or GUI, storing the NDMP configuration parameters in the Samba Registry. • In addition, the management operations to store and retrieve NDMP configuration parameters, view NDMP session information and NDMP log information, and stop currently running NDMP sessions can be performed through the Storwize V7000 Unified system CLI or GUI.

  • 10. • An NDMP backup session provides backup of a specific directory in an IBM General Parallel File System (IBM GPFS™) and all files and subdirectories contained within the file module of the Storwize V7000 Unified system. Besides the basic data of the files and directories, all extended GPFS attributes are saved for every file and directory. In order to provide the provision to back up a directory structure at a given point in time, a snapshot is used and it is actually the snapshot of the directory structure that is backed up. This snapshot also accounts for files that might be open or in use during the backup, as a point-in-time representation of the file is backed up by NDMP. • An NDMP restore session restores all the files and directories in the proper structure of subdirectories, and so on. In addition to the actual file contents, the GPFS extended attributes are also restored.Storwize V7000 Unified system NDMP command-line configurationThe following CLI commands (shown in Table 1) are available for configuring, monitoring, andmanaging the NDMP configuration parameters and NDMP sessions. # Storwize V7000 Unified CLI Usage description commands 1 cfgndmp Configure NDMP 2 cfgndmpprefetch Configuring NDMP backup prefetch 3 lsndmp List NDMP configuration List the actual contents of the NDMP log on the given file 4 lsndmplog module 5 lsndmpsession List NDMP session information Remove NDMP configuration information for a specified 6 rmndmpcfg NDMP node group 7 stopndmpsession Stop NDMP session 8 lsndmpprefetch List NDMP prefetch configurationTable 1: Storwize V7000 Unified system CLI command descriptionISV lab Storwize V7000 Unified system configurationIn the ISV lab: • The Storwize V7000 Unified system has one Storwize V7000 storage system for block access functionality. • The Storwize V7000 Unified system has two file modules for file-level access: mgmt001st001 and mgmt002st001 • The Storwize V7000 Unified system file cluster is defined as: st001.vsofs1.com Implementing an NDMP backup solution using EMC NetWorker on IBM Storwize V7000 Unified system 7

EitherGUI or CLI can be used to configure the NDMP node group. • An NDMP configuration can be defined only for an NDMP node group. • An NDMP node group need to be created before any other specific NDMP node group configuration parameters can be set. • An NDMP node group is created, configured, and activated appropriately, before an NDMP backup or restore can be configured on the EMC NetWorker data management application server. Note: The NDMP configuration parameters of a single file module of the Storwize V7000 Unified system cannot be changed individually.NDMP node group configuration using GUIPerform the following steps to configure the NDMP node group using GUI:1. Log in to the Storwize V7000 Unified system GUI using https://<Address>:10812. Click the File icon in the left-hand side and click Services to start configuring NDMP backup.

  • 16. Configuring Storwize V7000 Unified system NDMP backup prefetch The NDMP backup prefetch function navigates the directory that is being backed up, reading files in advance to the files actually coming due to be backed up. The prefetch function opens files in read-only mode and places the files in the file module’s cache for improved backup performance. The NDMP backup prefetch function is designed to work on files that are less than or equal to 1 MB in size. Restriction: The NDMP backup prefetch function does not work for a file system that has a block size greater than 1 MB. • To activate the NDMP backup prefetch function, use the cfgndmpprefetch CLI command with the --activate option. Specify the NDMP node group to enable the NDMP prefetch function with the NDMP node group. cfgndmpprefetch -c st001.vsofs1.com IFS2_NDMP_GRP --activate Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that the prefetch function for NDMP will be activated when NDMP is activated. • To set a limit on the number of applications that can work simultaneously, use NDMP backup prefetch for a node (including multiple instances of the same program such as multiple NDMP sessions) and use the cfgndmpprefetch CLI command with the --applimit option. cfgndmpprefetch –c st001.vsofs1.com IFS2_NDMP_GRP --applimit 4 Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that the configuration for the prefetch function for NDMP has been updated. • To set a limit on the number of prefetching threads per file module, use the cfgndmpprefetch CLI command with the --numThreads option. cfgndmpprefetch –c st001.vsofs1.com ndmp_node_grp1 --numThreads 100 Note: The value for the --numThreads option must be a positive integer greater than 50 and less than or equal to 180. The default value is 100. • To display the NDMP backup prefetch status information, use the lsndmpprefetch CLI command using the -s or --status option, and optionally adding the -g option to limit display to the specified NDMP node group.

  • 18. Notes: 1. IBM Tivoli Storage Manager backup / restore and NDMP backup / restore provide the same basic functionality of backing up or restoring file systems and the directories and files within the file systems. It is not recommended and not supported to have both Tivoli Storage Manager backup restore processing and NDMP backup restore processing being used on the same Storwize V7000 unified system for file modules. 2. NDMP backups are normally scheduled operations, which can be scheduled at a time when other activity, such as general purpose file serving, is low. If possible, it is recommended performing NDMP backup during periods when other file serving activity is generally lower, perhaps late in the evening or early in the mornings. 3. NDMP backup or restore processing significantly interferes with other Storwize V7000 Unified system file access functions, such as network file serving (CIFS, NFS, FTP, and HTTP). Many file module functions invoke the GPFS policy engine to evaluate a GPFS policy to determine the list of files to operate on. These include: • Tivoli Storage Manager backup processing • Tivoli Storage Manager HSM processing • NDMP incremental backup processing • Asynchronous replication processing • The runpolicy CLI command and others The GPFS policy engine scans the file system metadata to determine the files that match the criteria specified in the policy. This scan of the file system metadata can generate a significant amount of I/O to the storage systems to read all the file system metadata, especially for file systems containing very large number of files. Therefore, it is recommended not to start all the Storwize V7000 Unified functions at exactly the same time, but instead these functions be staggered over time. Considerations for EMC NetWorker DMA for Storwize V7000 Unified system NDMP backup You need to take care of the following considerations for EMC NetWorker DMA for NDMP backup. 1. Obtain either the IP address or host name to be used for this NDMP session. − Host name: Configure a DNS server with a common host name mapped to all of the IP addresses that are associated with the network group that in turn is associated with the NDMP node group. If this hostname is used, any of the file modules that are associated with the NDMP node group can be assigned based on a round robin IP address assignment from the DNS server. − IP address: Submit the lsnwinterface CLI command using the -x option on the active management file module and choose an IP address or multiple IP addresses if multiple backup policies are to be run simultaneously. This method is useful when multiple NDMP backup policies are used and you want to distribute the NDMP workload across multiple file modules and ensure that the same file module will not be used for all of the backup policies that will be run from the data management application server. Implementing an NDMP backup solution using EMC NetWorker on IBM Storwize V7000 Unified system 15
  • 19. 2. Configure the EMC NetWorker data management application server with the configuration parameters of the NDMP server for the file modules that are available to perform NDMP services, including the username and password associated with the NDMP node group. If a port other than 10000 was selected for the NDMP control port, then that control ports information needs to be configured on the data management application server.Monitoring NDMP session on the Storwize V7000 Unified systemNote: Read this information after configuring EMC NetWorker NDMP configuration and stagingappropriate NDMP backup or restore. Refer to the “EMC NetWorker NDMP configuration” section formore information.• The lsndmpsession CLI command enables to monitor the NDMP sessions on Storwize V7000 Unified system. Use the -n or -nodes option to view NDMP sessions running on specified file module or with the -g or --nodeGroupName option to view NDMP sessions running on specified NDMP node groups. Only file modules can be specified when using the -n or --nodes option. Multiple file modules and multiple node groups in a list must be separated with commas. If no file module or node groups are specified, the output displays information for both the file modules in the cluster. To determine the file modules that are running NDMP sessions for an NDMP node group, submit the following command to display the file modules that have NDMP sessions running and the sessions that are running on the file modules. lsndmpsession –c st001.vsofs1.com -n mgmt001st001 Or lsndmpsession –c st001.vsofs1.com –g IFS2_NDMP_GRP• Use the CLI lsndmpsession command with the -i or --sessionID option to view the verbose information of the NDMP session identified by the specified session ID running on the specified file module. lsndmpsession –c st001.vsofs1.com -n mgmt001st001 -i 1284990Monitoring NDMP log information on the Storwize V7000 Unified systemYou can view NDMP log using the lsndmplog CLI command.• Use the CLI lsndmplog command with the -n or --nodes option to view all the NDMP log information related to the specified file module. In the following example, the file module mgmt001st001 is specified: lsndmplog -c st001.vsofs1.com -n mgmt001st001• Use the CLI lsndmplog command with the -l or --lines option to view the most recent lines of the NDMP log information related to the specified file module.

  • 32. IBM Storwize V7000 Unified system NDMP backup environmental variablesThis section illustrates Storwize V7000 Unified system NDMP backup environmental variables details andhow to configure environmental variables for the NetWorker client.There are specific Storwize V7000 Unified system NDMP environment variables that are treated asparameters and can be passed to the NDMP server from data management applications performingNDMP backups. The following two parameters can be configured through data management applications. • BACKUP_GROUP_NAME: This is the name of a backup group where all the backup directories within the backup group share the same Storwize V7000 Unified system snapshot. − Note 1: The way to set this environment variable is to have a line similar to the following in the application information of NDMP client: BACKUP_GROUP_NAME=NDMP_group − Note 2: If the BACKUP_GROUP_NAME begins with NDMP_EXISTING then it is assumed that the Storwize V7000 Unified system is configured to use a snapshot, which has a name corresponding to this environment variable value. In this special case, it is also assumed that the user will delete the corresponding snapshot manually. − Note 3: The maximum length of the backup group name is 32 characters (inclusive of a possible NDMP_EXISTING). • BACKUP_GROUP_EXPIRATION: This parameter helps to configure the amount of valid time that the snapshot is associated with BACKUP_GROUP_NAME. After the age of the snapshot has surpassed the expiration value, a new snapshot will be taken and all new NDMP backup sessions associated with BACKUP_GROUP_NAME will use the new snapshot. This Storwize V7000 Unified system NDMP parameter is very important to effectively schedule level backups that have less than 1 hour level backup expiration schedule time. − Note 1: The way to set this environment variables is to have a line similar to the following line in the Application information of NDMP client: BACKUP_GROUP_EXPIRATION = 1_DAY Note 2: The following values are acceptable for this environment variable: • 0_SEC … 60_SEC • 0_MIN … 60_MIN • 0_HOUR … 168_HOUR • 0_ DAY … 31_DAY • 0_MONTH … 12_MONTH − Note 3: If no value is given for the expiration, the default will be 1 hour. − Note 4: If the user wants to ensure that a separate snapshot is taken for every directory, then an expiration value of 0_SEC need to be specified.
