Restoring storage groups to a primary volume

This section explains how to restore a storage group when backup data has been saved on a secondary
volume. This example restores the data from the secondary volume to the primary volume by
resynchronizing the volumes.

To restore a storage group:

1.

Check the backup ID of the backup data.

To check the backup ID of the backup data used to restore it from a secondary volume to the
primary volume, execute the

drmexgcat

command on the database server.

DBServer> drmexgcat

STORAGEGROUP: STORAGE_1

BACKUP-ID:0000000001 BACKUP-MODE: COLD STORAGEGROUP: STORAGE_1 ORIGINAL-ID:0000000001

file. Here, use operation ID

Operation_A

DBServer > EX_DRM_BACKUPID_SET Operation_A -backup_id 0000000001

on the database server to restore the data from the secondary

volume to the primary volume by resynchronizing the volumes.

DBServer > EX_DRM_EXG_RESTORE Operation_A -resync
