system. This example restores the data from tape to a secondary volume, and then restores the data
from the secondary volume to the the primary volume by resynchronizing the volumes. This example
uses Operation_A as the operation ID that identifies the file system to be restored.
To restore the file system:
1. Check the backup ID of the backup data.
Check the backup ID of the backup data used to restore it from tape to the secondary volume.
To check the backup ID, execute the drmtapecat command on the backup server.
BKServer >drmtapecat -hostname FSServer -l
