  • Unique nameing SDIDIAG Imanger Plugin PKI
  • Bonding (Laver 2) vs. Netware Teaming (Layer 3) Be aware of spanning tree algorithms
  • After about 1 hour !!
  • LUM Config: - Convert lower -&gt; Converts users to lower case for Linux box if in Edir some ore upper and some are lower - persistent search disable - user cache only if eg. Backup software does not query into edir for the owner of files - preferred servers
  • /dnsnames for iPrint to convert used IP addresses of printers do dns names -&gt; Problem after migration to OES2 the workstations still want to print to the ipp://10.10.10.10 address !! - disable quota in nss /noquota... for the migration (100MB quota on directory -&gt; but 10GB already in there -&gt; so you can&apos;t migrate due to the quota limit if parameter not used)

    83. 83. Test all services before users are moved and affected
    84. 84. Did you backup just before migration starts?
    85. 85. Execute the migration with your checklist for each action
    86. 86. Have a subset of users from the business available for post migration tests
    87. 87. Disable access to the migrated services and data </li></ul>
    88. 88. Step 6: Cleanup and Decommission <ul><li>Let the new servers run for some time before old one get deleted and switched off
    89. 89. Make a plan to retire the old servers </li><ul><li>Get replicas off

    96. 96. Identify tree CA requirements
    97. 97. License codes from Customer Center?
    98. 98. Backup of source server eDirectory ™ DIB </li></ul><li>List of which Open Enterprise Server services need to be migrated: </li><ul><li>iPrint, Novell Storage Services ™ , DNS/DHCP, FTP, iFolder*, eDirectory ™
    99. 99. These services need to be installed when we install Open Enterprise Server 2 </li><ul><li>Pre-requisite of the migration tool </li></ul></ul></ul>
    100. 100. Lab 1 : Pre-flight Checks <ul><li>Please consult your lab guide for this exercise </li></ul>
    101. 101. Building the Target Server
    102. 102. Building The Target Server <ul><li>Software requirements </li><ul><li>SUSE ® Linux Enterprise Server (SLES) 10 SP3
    103. 103. Open Enterprise Server (OES) SP2 </li></ul><li>Version numbers must be matched, so </li><ul><li>SLES10 SP4 + OES2 SP3 (when available)
    104. 104. SLES10 SP2 + OES2 SP1
    105. 105. SLES10 SP1 + OES2 FCS and so on.. </li></ul><li>Open Enterprise Server is now an add-on product that installs on top of SLES10 </li><ul><li>Unlike OES1, which was merged into the main SLES9 install
    106. 106. Slightly different installation than OES1, but more intuitive </li></ul></ul>
    107. 107. Building The Target Server <ul><li>Partitioning scheme </li><ul><li>By default, SUSE ® Linux Enterprise Server will give you a swap partition and a root (/) partition, formatted with ReiserFS
    108. 108. For test/practice, feel free to play around with this </li></ul><li>Consider the role of the server and partition accordingly </li><ul><li>High file I/O? EXT3, XFS
    109. 109. Novell ® file share? Novell Storage Services ™
    110. 110. Consider partitioning /boot, /var, /tmp, /swap, / as a minimum
    111. 111. Use LVM Logical Volume Manager to be flexible
    112. 112. If it is a ZENworks ® Configuration Management Primary server, /var partition is a must
    113. 113. If partitions will rapidly grow in size, isolate them from other parts of the disk to avoid problems later </li></ul></ul>
    114. 114. Building The Target Server <ul><li>Open Enterprise Server 2 SP2 server will be built in the same container as existing NetWare ® server FS1
    115. 115. To ensure we have all the packages we need, we must have :-) </li><ul><li>All services to be migrated (iPrint, Novell Storage Services ™ etc.)
    116. 116. Pre-migration server pattern installed (mandatory)
    117. 117. gcc and kernel-sources packages for VMware Tools
    118. 118. Print server pattern unchecked if we are installing iPrint </li><ul><li>CUPS will fight with iPrint if we install both!
    119. 119. Easier to remove at the start than later in the process when dependency chains make this difficult </li></ul></ul></ul>
    120. 120. Building The Target Server <ul><li>In order to use Novell Storage Services ™ (NSS) without EVMS, we need to use two separate virtual disks </li><ul><li>OS and application files on disk 0
    121. 121. NSS volumes on disk 1 </li></ul></ul>Disk 0 SYS DATA Disk 0 Disk 1 / DATA
    122. 122. Building The Target Server <ul><li>Refer to lab guide for this exercise. </li></ul>
    123. 123. NetWare ® vs. Open Enterprise Server Linux
    124. 124. NetWare ® vs. Open Enterprise Server Linux <ul><li>NetWare is a 32 bit operating system </li><ul><li>Maximum 4GB of addressable memory </li></ul><li>Entered Extended Support phase in March 2010 </li><ul><li>Required current maintenance contract
    125. 125. Extended Support ends March 2012 </li></ul><li>What is Extended Support? </li><ul><li>Installation and configuration support
    126. 126. Critical security updates only
    127. 127. Knowledgebase / forums / documentation / existing patches
    128. 128. Transitionary step only ! </li></ul></ul>
    129. 129. NetWare ® vs. Open Enterprise Server Linux <ul><li>Linux scales further than NetWare </li><ul><li>64 bit support allows for much more physical RAM than 32 bit (though this is hardware dependent for a definitive figure)
    130. 130. Most code executes in protected memory, not all NLMs will allow this, but those that do must be configured appropriately
    131. 131. Technically, NLMs run with full server privileges
    132. 132. Linux daemons are similar to NLMs, but can be set to run as a specific (or “service user”) user to limit damage in case of hacking/software issue
    133. 133. Many more applications certified for Linux than for NetWare </li><ul><li>Oracle
    134. 134. ZENworks ® Configuration Management </li></ul></ul></ul>
    135. 135. NetWare ® vs. Open Enterprise Server Linux <ul><li>Executing programs/applications </li><ul><li>NetWare generally uses NLMs and </li><ul><li>NCFs (batch files) these are called shell scripts on Linux </li></ul><li>Linux does not take file extensions into account as Windows </li><ul><li>.exe = Windows Executable
    136. 136. .exe = Could be executable on Linux, could be spreadsheet for all we know!
    137. 137. Linux permissions define whether or not code is executable and for whom (to make executable use: chmod +x <program_name>) </li></ul><li>NetWare is not case sensitive, Linux is </li><ul><li>MyExpenses.xls is not the same as myexpenses.xls </li></ul><li>Permissions are different between Novell Storage Services ™ and POSIX file systems </li><ul><li>RWCEMFA for NSS
    138. 138. RWX for POSIX (R=Read, W=Write, X=eXecutable) </li></ul></ul></ul>
    139. 139. NetWare ® vs. Open Enterprise Server Linux <ul><li>NetWare offers only Novell Storage Services ™ file system, Linux offers a la carte selection for most appropriate use </li><ul><li>ReiserFS </li><ul><li>Good for many small files, journalling file system with metadata. Good all purpose file systems and can be used in most scenarios
    140. 140. Default file system in SUSE ® Linux Enterprise Server 10
    141. 141. Data recovery tools liable to failure and data loss </li></ul><li>EXT3 </li><ul><li>Quick, stable and mature Linux file system
    142. 142. Good for small files, journalling file system and good all purpose file system for use in most scenarios
    143. 143. Default file system in SUSE ® Linux Enterprise Server 11
    144. 144. Scalability issues with many files in a directory (>5000, without htree) </li></ul></ul></ul>
    145. 145. NetWare ® vs. Open Enterprise Server Linux <ul><li>Novell Storage Services ™ is also available on Open Enterprise Server 2 Linux </li><ul><li>Shipped with Open EnterpriseServer 1 in 2005, so mature implementation of a proven technology
    146. 146. Rich feature set, including data shredding, snapshot, compression, quotas, salvage etc.
    147. 147. Works in the same way as it does on NetWare </li><ul><li>Managed in the same way, iManager etc.
    148. 148. Slighter learning curve coming from NetWare </li></ul><li>Good, multi purpose file system for most scenarios, though it should be tuned appropriately for use </li><ul><li>Salvage, compression, flush files immediately turned off for GroupWise ®
    149. 149. Consider noatime and nodiratime mount commands to improve throughput
    150. 150. Turn off functionality you don't explicitly need! </li></ul></ul></ul>
    151. 151. Services Ported to Linux
    152. 152. Services Ported To Linux Novell Storage Services ™ NetStorage QuickFinder IManager and ConsoleOne ® DNS / DHCP Novell Client ™ NCP ™ Access eDirectory ™ AFP iPrint Apache Web Server Backup / Restore (SMS) CIFS / DFS iFolder* Novell Cluster Services ™

    195. 195. NFS storage on another server on the network
    196. 196. ISO file on a server (handy for installing software!) </li></ul></ul></ul>
    197. 197. Managing Your Open Enterprise Server (OES) <ul><li>Using Linux runlevels </li><ul><li>Runlevels runs from 0 to 6, inclusive </li><ul><li>Init 0 – shutdown
    198. 198. Init 1 – single user only, no network or services (aka “safe mode”)
    199. 199. Init 2 – multiuser access, no network or services
    200. 200. Init 3 – multiuser access, networking, services, no GUI

    217. 217. Managing Your Open Enterprise Server (OES) <ul><li>How do we create Novell Storage Services ™ (NSS) pools and volumes? </li><ul><li>Same way as we do on NetWare ® now!
    218. 218. NSSMU at the server console (must be root)
    219. 219. iManager on the server, or use the workstation version </li></ul><li>Differences between NCP ™ and NSS volumes </li><ul><li>NSS volumes are disk pieces, carved up and formatted with the NSS file system
    220. 220. NSS volumes provide compression, quotas and all the good stuff you get on NetWare currently
    221. 221. NCP volumes are chunks of the Linux file system presented as “Novell ® ” volumes </li><ul><li>They look the same on a Windows client device
    222. 222. SYS volume on an OES2 Linux server is an NCP volume </li></ul></ul></ul>
    223. 223. Managing Your Open Enterprise Server (OES) <ul><li>When to use an Novell Storage Services ™ volume? </li><ul><li>When you want “regular” Novell ® file services
    224. 224. When you want compression, quotas, salvage etc.
    225. 225. When you want rich permission sets
    226. 226. Physical disk should be separate from OS disk, so we don't have to configure EVMS
    227. 227. When creating volumes for migration from NetWare ® </li></ul><li>When to use an NCP ™ POSIX volume? </li><ul><li>No general use, aside from the install provided SYS volume
    228. 228. Can be useful to expose part of the Linux file system to Novell Clients
    229. 229. For example, an installation point (GroupWise ® SDD) </li></ul></ul>
    230. 230. Linux User Management - When/Why?
    231. 231. Linux User Management – When/Why? <ul><li>What is Linux User Management? </li><ul><li>Called LUM for short
    232. 232. Linux has it's own local database of users, much like Windows in some respects
    233. 233. Linux native services such as FTP, rlogin, SSH etc assume the presence of a local user, or configured authentication source such as LDAP, NIS etc.
    234. 234. LUM allows eDirectory ™ users to access Linux servers using their current eDirectory username and login credentials
    235. 235. Some Open Enterprise Server 2 services also require LUM to be present </li><ul><li>Novell Storage Services ™ (NSS)
    236. 236. iPrint, Samba
    237. 237. Defaults generally work quite well </li></ul></ul></ul>
    238. 238. Using The Migration Tool
    239. 239. Using The Migration Tool <ul><li>The tool is a core part of the Open Enteprise Server 2 installation and does not need to be downloaded separately
    240. 240. Can be accessed via YaST menu or by running miggui from a command prompt/terminal window
    241. 241. Tool provides two main features: </li><ul><li>Transfer ID
    242. 242. Server Consolidation </li></ul><li>We are going to use the Transfer ID migration </li><ul><li>Easiest and quickest way of demonstrating the tool's capabilities
    243. 243. Many migration scenarios involve a one to one migration of data and services away from NetWare ® </li></ul></ul>
    244. 244. Using The Migration Tool <ul><li>The tool essentially has two parts </li><ul><li>Copy data and configs from the source NetWare ® server
    245. 245. Perform the ID transfer, so eDirectory ™ , replicas, IP addresses etc. move to Linux from NetWare </li></ul><li>Build your Open Enterprise Server 2 Linux target in the same container if possible </li><ul><li>Makes life a little easier as we go </li></ul><li>Some backout procedures exist, in case of failure </li><ul><li>Each step can be re-tried, for example if there are comms issues </li></ul><li>O nce iPrint is migrated, you cannot go back
    246. 246. Remember, data is copied , so you lose nothing! </li></ul>
    247. 247. Lab 3 : Running the Migration Utility <ul><li>Refer to lab guide for this exercise. </li></ul>
    248. 248. Configure New Services In Open Enterprise Server 2
    249. 249. Configure New Services in Open Enterprise Server (OES) 2 <ul><li>OES2 brings two new services we're interested in </li><ul><li>iFolder 3.8
    250. 250. Dynamic Storage Technology </li></ul><li>iFolder 3.8 is slightly different than iFolder 2.x </li><ul><li>Concept of shared folders
    251. 251. iFolder 2.x had one to one relationship with user and server
    252. 252. iFolder 3.x allows folders to be shared with other iFolder users
    253. 253. Re-written in Mono ® , so Linux only
    254. 254. Clients for Mac, Linux and Windows XP/Vista/7
    255. 255. iFolder data store migration utility available in YaST
    256. 256. Can be clustered, if required </li></ul></ul>
    257. 257. Configure New Services in Open Enterprise Server (OES) 2 <ul><li>What is Dynamic Storage Technology? </li><ul><li>Put simply, it allows administrators to manage file storage in a policy based way
    258. 258. Server volumes have shadow volumes defined
    259. 259. Depending in the policy, files can be transparently moved from the “main” volume to the shadow volume
    260. 260. For example, policy states MP3's are to be stored on the shadow volume, along with files not accessed since 2008
    261. 261. Free in OES, perhaps on of the best app in the whole suite Saves a lot of money!
    262. 262. Allows backup times to be reduced to keeping stale data away from the live data
    263. 263. Prevents old/non-mission critical data from clogging up expensive storage </li></ul></ul>
    264. 264. Configure New Services in Open Enterprise Server (OES) 2 <ul><li>How do I configure Dynamic Storage Technology? </li><ul><li>Policies are configured in Novell ® RM
    265. 265. Can apply policies to both Novell Storage Services ™ (NSS) and NCP ™ volumes
    266. 266. Decide on how you want to manage your data before you think about how you want to configure DST policies
    267. 267. Use the inventory functionality available to you to find out what is on your NSS volumes before you decide on your DST policies
    268. 268. Don't forget a Novell Client™ is installed on the OES2 Linux server, so don't be afraid to use that to check if your policies are working, you don't need a Windows client as such </li></ul></ul>
    269. 269. Wrap Up / Question and Answer
    270. 270. Wrap Up / Question and Answer <ul><li>If you're new to Linux: </li><ul><li>Take some Novell ® curriculum courses (classroom, online etc.)
    271. 271. Build, test, break, rinse, repeat
    272. 272. Use virtual machine snapshots in your lab to speed things up </li></ul><li>In your production environment: </li><ul><li>Consider login scripts, server migration/consolidation issues
    273. 273. Remember to catalogue all of your apps, including GroupWise ® , ZENworks ® , Novell Identity Manager etc. Will they run on Linux? Third party products, GWAVA, anti-virus etc.
    274. 274. Service Location Protocol </li><ul><li>Not quite the same on Linux, OpenSLP is not Novell's SLP
    275. 275. Windows 7 clients look for OpenSLP Directory Agents
    276. 276. Consider DNS names in login scripts for faster script processing </li></ul></ul></ul>
