This section describes the procedure for moving a paired logical volume to a new 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 source paired logical volume group 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 group to be added.
   • Change the paired logical volume group name of the paired logical volume being moved to the name of the newly added paired logical volume group.
7. Execute the horcmstart command to start RAID Manager.
8. Execute the paircreate command for the following paired logical volume groups:
   
   • Source paired logical volume groups
   • Destination paired logical volume groups
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 groups at both the source and destination are 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.
