Guidelines for using IBM DB2 Universal Database (UDB) with HP StorageWorks Storage Mirroring (T2558-96335, June 2009)

• Restore To—The name of the machine where the data will be restored. This may or may not
be the same as the original source machine.
13. Identify the correct drive mappings for the data and any other restoration options necessary. For
detailed information on the restoration options, see the HP StorageWorks Storage Mirroring
user’s guide.
14. Select the Use block checksum comparison/delta block transfer option.
15. On the Orphans tab, select Delete Orphaned Files.
16. Verify that the selections you have made are correct and click Restore. The restoration procedure
time will vary depending on the amount of data that you have to restore.
17. After the restoration is complete, start the DB2 services on the source machine.
18. Reestablish the Storage Mirroring replication set connection.
19. On the Mirroring tab, select File differences with the Use block checksum option.
NOTE:
If the target has been previously mirrored to or restored, select File differences with the Use
block checksum option so that only the changed data is sent across the network.
At this time, your data is restored back to your source machine, the source machine is again the
primary DB2 server, and, if you selected to continue failover monitoring, the target is available to
stand in for the source in the event of a failure.
