When the system switchover facility is used, an operating HiRDB can be updated in the following cases:

• Standby system switchover
  This can be done only when the system that is running is operating as the primary system. When the system that is running is operating as the secondary system, execute the command after performing system switchover.
  
• Standby-less system switchover
  This can be done only when all normal BESs are operating. Switchover cannot occur when alternating.
  

The following describes how to update to the HiRDB update version when the system switchover facility is used.

• When operating in server mode
  Standby system switchover
  
  1. If the secondary system is running, perform system switchover in such a manner that the primary system will be running after the switchover.
  2. Terminate the standby system.
  3. Use the running system to update to the HiRDB update version.
  4. Use the pdsetup -d command to delete the HiRDB standby system from the OS (respond with y to the KFPS00036-Q message).
  5. Perform overwrite installation of the HiRDB update version on the standby system.
  6. Use the pdsetup command to register the HiRDB standby system with the OS.
  7. Re-start the standby system terminated in step 1. On the standby HiRDB system, execute the pdstart command (for a HiRDB/Parallel Server, execute the pdstart -q command).
  Standby-less system switchover (1:1)
  
  1. If the alternate BES is running, switch back the system.
  2. Remove the alternate portion from waiting status. For details about the procedure, see the manual HiRDB Version 8 System Operation Guide.
  3. On the normal BES unit that is running, update to the HiRDB update version.
     Because the alternate portion that was removed from waiting status in step 2 goes into waiting status automatically when the pdprgrenew command is executed, no other action is required.
     
  Standby-less system switchover (effects distributed)
  
  1. If the accepting unit's guest BES is running, switch back to the normal unit.
  2. Release the acceptable status of all inactive guest BESs that belong to the HA group.
  3. On the running normal unit, update to the HiRDB update version.
     Because the guest BESs whose acceptable status was released in step 2 go into acceptable status automatically when the pdprgrenew command is executed, no other action is required.
     
• Operating in monitor mode
  
  1. If the secondary system is running, perform switchover so that the primary system will be running.
  2. On the running system, update to the HiRDB update version.
  3. Use the pdsetup -d command to remove the HiRDB standby system from the OS (respond with y to the KFPS00036-Q message).
  4. On the standby system, perform overwrite installation of the HiRDB update version.
  5. Use the pdsetup command to register the HiRDB standby system with the OS.
