Configuring IBM Storage Protect server on a secondary node for PowerHA with a separate Db2 instance

Edit online

You must create an IBM Db2 instance on each secondary node if the Db2 instance directory, /home/tsminst1/sqllib, is not shared between the nodes in the PowerHA® cluster.

About this task

You can configure the IBM Storage Protect server on a secondary node by using the dsmicfgx wizard or manually.

Procedure

  • To create a Db2 instance on a secondary node by using the dsmicfgx wizard, complete the following steps:
    1. Run the dsmicfgx wizard.
    2. From the Instance Directory pane, select the Check this if you are configuring the server instance on a secondary node of a high availability cluster check box.
  • To create a Db2 instance on a secondary node manually, complete the following steps:
    1. Move all the shared resources to the secondary node.
    2. Create a Db2 instance by issuing the following db2icrt command: 
      /opt/tivoli/tsm/db2/instance/db2icrt -s ese -u instance_user instance_user
      where instance_user is the same user that owns the Db2 instance on the primary node.
    3. When the Db2 instance is created, log in as the instance user or by issuing the su command: 
      su - <instance_user>
    4. As the instance user, issue the following commands: 
      db2start
db2 update dbm cfg using DFTDBPATH  shared_db_path 
db2 catalog db TSMDB1
db2stop
      where shared_db_path is the shared database directory. The shared database directory is typically the server instance directory.
      Tip: To determine the shared_db_path value, issue the following command on the primary node: 
      db2 get dbm cfg | grep DFTDBPATH
    5. Update the following variables in the /opt/tivoli/tsm/server/bin/startserver script, by using the following values:
      Table 1. Variables in the /opt/tivoli/tsm/server/bin/startserver script
      Description Variable Example
      Set the INST_USER to the instance user ID. INST_USER INST_USER='tsmuser1'
      Set the INST_DIR to the location of the IBM Storage Protect instance directory. This directory contains dsmserv.dbid and dsmserv.opt. INST_DIR INST_DIR='/home/tsmuser1/tsminst1'
      Select one of the following startup options:

      Option 1 - use instance:

      $INST_USER but run the server as root (-U)

      Option 2 - use instance:

      $INST_USER and run the server as $INST_USER (-u)

      		 INST_OPTION

      Option 1:

      INST_OPTION='-U $INST_USER'

      Option 2:

      INST_OPTION='-u $INST_USER'
    6. Start the server by issuing the following script: 
      /opt/tivoli/tsm/server/bin/startserver
    7. When the server is started, issue the BACKUP DB command to verify that the data is successfully backed up.
