Installation Instructions ************* Full installation instructions can be found in document "IBM System Storage TS7600 with ProtecTIER Installation Roadmap Guide for the TS7650 Appliance [3958 AP1]" (gc53119405.pdf). Conccurent upgrades for this version are not supported. The vtfd and ptcluster processes should be stopped on both nodes before upgrading. Upgrades from V2.5.4.0 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. Important: If the 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. Upgrading TS7650 Appliance ----------------- Choose one of the following options: a) Upgrade installation on top of TS7650G V2.5.X code: To upgrade from v2.5.X, use this code V2.5.4.0 and follow the procedure described in the "Software Upgrade and Replication Enablement Guide" (gc53119605.pdf), Chapter 6, "Installing and configuring the ProtecTIER v2.5.x upgrade" Important: stop vtfd and ptcluster services for both nodes before starting the upgrade. b) For an upgrade installation on top of TS7650AP1 V2.4.X code: To upgrade from v2.4.X.X, use this code V2.5.4.0, and follow the procedure described in the "Software Upgrade and Replication Enablement Guide" (gc53119605.pdf), Chapter 6, "Installing and configuring the ProtecTIER v2.5.x upgrade" c) For an upgrade installation on top of TS7650AP1 V2.3.X code (the procedure is built based on the upgrade from v2.3 -> v2.4, then to v2.5.4): For Upgrade from v2.3.X, use the following procedure described in the "Software Upgrade and Replication Enablement Guide" (gc53119605.pdf) Chapter 5, "Upgrading v2.3.x.x servers to v2.4.x.x", accordingly Continue the upgrade to v2.5.4 as outlined in item b) above. d) For an upgrade installation on top of TS7650AP1 V2.2.X code (the procedure is built based on the upgrade from v2.2 -> v2.3, v2.3 -> v2.4, then to v2.5.4): For Upgrade from v2.2.x to v2.3.x, use the the procedure described in the "Software Upgrade and Replication Enablement Guide" (gc53119604.pdf) Chapter 5, Sub-Section "Preparing for the 2.4.1.x upgrade" Continue upgrading v2.3 -> v2.4 and to v2.5.4, as mentioned in item c) above IMPORTANT: IBM DS4700 and DS5000 array USERS THAT INTEND TO CHANGE THE DISK ARRAY HOST TYPE TO 'LNXCLVMWARE' and DS5000 array USERS with FIRMWARE 07.70.23.00 NEED TOCHANGE THE DISK ARRAY HOST TYPE TO 'LNXCLUSTER' MUST FOLLOW THE INSTRUCTIONS DETAILED IN THE TECHNOTE "ProtecTIER and DS4000&DS5000 AVT setting" : http://g01zciwas003.ahe.pok.ibm.com/support/dcf/preview.wss?host=g01zcidbs003.ahe.pok.ibm.com&db=support/ssg/ssgtech.nsf&unid=922465B0CF23145B8525771400282D19&taxOC=STVRB7&MD=2010/04/29%2001:04:59&sid= Installation procedure can be done from TSSC as well. In order to install by TSSC: a) Log into the TSSC with userid: service and password: service. A blue screen appears. b) Right click on the blue screen and a selection menu is displayed. c) Select Terminal from menu and a command line terminal session opens. d) Enter: ssh ptadmin@172.31.1.xxx where xxx is what eth5 (DD3 server and upgradable DD1 server) or eth3 (not upgradable DD1 server) is set for on the TS7650AP1. If the ssh key has not been accepted, answer yes to the question. Then insert the password as needed. Once the password is entered, you are on a command line for the TS7650AP1. Continue with code upgrade procedure according to your current version and relevant documentation for this version. You can find the links above. ------------------------------------------------------------------------------- 7. Additional Documentation TS7600 support homepage contains all relevant documentation. It can be found under: http://www-01.ibm.com/support/search.wss?rs=0&tc=STVRB7&q=ssg1*&sort=desc&dc=DA400+DA100+DA110+DA120+DA450+DA300&dtm (search for keyword 'ProtecTIER') ------------------------------------------------------------------------------- 8. Known Issues and Restrictions in this Level Connectivity of ProtecTIER server to IBM i/VIOS /AIX based hosts is not supported with this version. 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 128 Use max 128 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_V2.5.4.0 should work with TSSC code level 5.9.8 or higher. Server patch PT_Linux_V2.5.4.0 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 -------------------------------------------------------------------------------
