becomes lost. Moreover, if the copy is placed on a Storage Center volume, the Storage Center can be used to replicate
the volume to a remote Disaster Recovery (DR) site for additional safekeeping. By default, backup set information is not
copied to another location.
Mapping LUN Range (Low/High): Use these fields to specify a range of LUNs to be used by Replay Manager to map
volumes back to a server. Default is 1 through 254.
Storage Center Connection Timeout (sec): Use this option to set a timeout value in seconds for the Replay Manager
connection time to the Storage Center. The default is 300 seconds.
NOTE: Replay Manager first attempts to expire Replays without mapping the Replay to a server. If Replay Manager
cannot expire the unmapped Replay, it maps the Replay back to the server to expire the Replay. In this case, the number
of available LUNs must be equal to or greater than the total number of unexpired Replays managed by Replay Manager.
If no LUNs are available, backups will fail and Replay Manager will be unable to expire transportable snapshots.
