17.8.1 Adding, deleting, or expanding data DB areas (in the case of the cold standby configuration)

Use WWNs because the same logical units must be specified in the active system and the standby system.

■ When using SCSI reservation for shared disk

When using SCSI reservation for shared disk, you need to change the operand specification in the servers file of HA Monitor. The following shows the procedure.

• Procedure (when adding or expanding a data DB area):

  1. Terminate the cold standby configuration normally.

     For details about how to terminate the cold standby configuration, see 17.4.2 How to terminate the cold standby configuration.

  2. Change the specification of the servers file of HA Monitor.

     Add the device name of the disk to be added in the scsi_device or dmmp_device operand. Change the specification of the servers file in both the active system and the standby system.

  3. Start the cold standby configuration normally.

     For details about how to start the cold standby configuration, see 17.4.1 How to start the cold standby configuration.

  4. Add or expand a data DB area by executing the adbmodarea command.

     For details about how to add data DB areas, see 11.10.1 Adding data DB areas.

     For details about how to expand data DB areas, see 11.10.3 Expanding a data DB area (adding a data DB area file).

• Procedure (when deleting a data DB area):

  1. Delete a data DB area by executing the adbmodarea command.

     For details about how to delete data DB areas, see 11.10.2 Deleting a data DB area.

  2. Terminate the cold standby configuration normally.

     For details about how to terminate the cold standby configuration, see 17.4.2 How to terminate the cold standby configuration.

  3. Change the specification of the servers file of HA Monitor.

     Delete the device name of the deleted disk from the scsi_device or dmmp_device operand. Change the specification of the servers file in both the active system and the standby system.

  4. Start the cold standby configuration normally.

     For details about how to start the cold standby configuration, see 17.4.1 How to start the cold standby configuration.
