Introduction This document is a reference for installation and other useful information regarding version 2.5.5.0 of IBM System Storage TS7610SM1 software. This document refers to both Small and Medium products ------------------------------------------------------------------------------- 2. Available Education N/A ------------------------------------------------------------------------------- 3. Prerequisites - PT Manager V2.5.X must be installed. - This patch requires that the full package code be already installed on the system. This patch will fail to install on a fresh Linux OS installation. - RAS should be configured before upgrade. First RAS configuration for 2.5 code level installed on DD3/DD1 machines isn't supported. This action will fail and will require scratch installation. - For customers upgrading from code level 2.5 or 2.1, prerequisite details can be found below in section 6. ------------------------------------------------------------------------------- 4.

Installation Instructions Full installation instructions of VTL system can be found in document "IBM System Storage® TS7610 ProtecTIER® Deduplication Appliance Express Installation and Setup Guide for VTL Systems" (ga32077701.pdf). Full installation instructions of OST system can be found in document "IBM System Storage® TS7610 ProtecTIER® Deduplication Appliance Express Installation and Setup Guide for OpenStorage Systems" (ga32083600.pdf). "IBM System Storage® TS7610 ProtecTIER® Deduplication Appliance Express Installation and Setup Guide" (ga32077700.pdf). http://www-01.ibm.com/support/docview.wss?uid=ssg1S7003268&aid=1 Full installation instructions can be found in document "Installation and Setup Guide for VTL Systems" (ga32077701.pdf). Important: If RAS package was already configured on a server, it is not necessary to use ./ptconfig to reconfigure it. The server's RAS settings will not be overwritten or altered as a result of the software upgrade process Upgrades from V2.5.5.0 and higher to V3.1.0.X and V3.1.1.X are not supported. If you are at one of those levels, please upgrade to V3.1.2.0 or higher. Upgrading TS7610SM1 ----------------- Refer to document "IBM System Storage® TS7610 ProtecTIER® Deduplication Appliance Express Software Upgrade Guide" (ga32083700.pdf) Remark - upgrade is relevant only for VTL installations ------------------------------------------------------------------------------- 7.

Known Issues and Restrictions in this Level Do not perform any configuration operation if both nodes of the cluster do not have the same patch level. Do not move a cartridge from the shelf of the remote repository while it's being replicated to. Issue ID Description Workaround -------- ------------------------------------------------- -------------------------------- 9035 PT Manager does not start up when working in Dual Mode Refrain from working with Dual Mode Display display with specific drivers of Nvidia graphic cards. 9149 When using ptcli for moving cartridges, vtfd service Call IBM Software Support can not be stopped until all cartridges are moved successfully. 10438 In case of service vtfd stop during config session, error message appears Restart VTFD in vtf_internal.log "Send GetCMState failed - AC_RPC_CANTSEND" 10445 /dev/cdrom and /dev/dvd disapear. Caused by DD4 IMM issue. Run Linux command /sbin/start_udev to re-create them 10636 Replication failure (rare). Following error appears in vtf_internal.log Call IBM support "NrmTriggerManager::LinkedList::IsValid: m_head is NRM_TRIGGER_MGR_NOT_A_PAGE && m_size = 1" 10892 Unexpected fence node in cluster may cause reboot to ProtecTIER node Call IBM support (rare RH issue). Fenced node starts up as Fenced. Following reboot, system will be fully functional 10994 After create repository, PT Manager GUI shows previous view Manually select the repository view 11063 The PT Manager GUI does not return to repository view after increase capacity Manually select the repository view 11089 R2.5-VTL-Chassis Event Log 100% full - preventing new HW error entries - Clear the logs as follows: needs to wrap or FIFO & Internal Error a) telnet TSSC b) type "readlog" and analyze the problem c) Quit readlog, and clear the entire log "clearlog" 11091 When setting, via PT Manager GUI, VTL port speed higher then card limit Call IBM support (set 8G for a 4G hardware) the system works in previous speed with no warning 12656 OST Restore max streams supported is 64 Use max 64 restore streams in OST 13224 Performing a bug check for both nodes when the cluster Reboot both nodes. After startup, the system resumes proper operation. internal network is disconnected from PT for a duration of 11 to 15 seconds. 13025 No connection when using loop on HP-UX Call IBM support ------------------------------------------------------------------------------- 9. Compatibility Server patch PT_Linux_V2.5.5.0 requires the use of PT_Manager_V2.5.0.0 or higher. The previous PT manager code is not compatible with this new server code level, therefore, it will fail to connect to it. You will have to install the new PT_Manager code in order to resolve this connectivity issue. All existing replication configurations are supported regardless of ProtecTIER version running on the repositories. New replication setup requires the use of V2.5 PT software. OST Plugin - System should work with Plugin 2.5.0.0 and above TS7650 compatiblity matrix: ftp://public.dhe.ibm.com/storage/tape/ts7650_support_matrix.pdf -------------------------------------------------------------------------------
