This section describes the procedure for adding a paired logical volume to an existing paired logical volume group.

Procedure

Note: The numbers to the left of the process boxes correspond to the item numbers in the following explanation:

1. Terminate HiRDB normally by executing the pdstop command.
2. Execute the pdcopy command (with the -M x option specified) to make a backup of each system.
   For details about how to make backups, see the HiRDB Version 9 System Operation Guide.
   
3. Copy the backup files made in step 2 to the remote site.
4. Split the paired logical volume group to which the paired logical volume is to be added by executing the pairsplit command (with the -S option specified).
5. Execute the horcmshutdown command to stop RAID Manager.
6. Change RAID Manager's configuration definition. Specify the definition information for the paired logical volume to be added.
7. Execute the horcmstart command to start RAID Manager.
8. Execute the paircreate command on the paired logical volume group to which the paired logical volume was added and re-generate the paired logical volume group.
9. Execute the pairevtwait command (with the -s pair option specified) to check the results of generating the paired logical volume group. Confirm that the pair status of the paired logical volume group to which the paired logical volume was added is PAIR.
10. Start HiRDB by executing the pdstart command.
11. Collect a synchronization point dump by executing the pdlogsync command (with the -w option specified). Confirm that the command terminates normally. For HiRDB/Parallel Server, execute the pdlogsync command on all servers.
