Activate Disaster Recovery for a Single Restore Point
To activate DR for a replication or Live Volume, use the corresponding restore point.
1 Click the Replications & Live Volumes view.
2 Click the Restore Points tab.
3 Right-click the restore point, then select Activate Disaster Recovery. The Activate Disaster Recovery dialog box appears.
If the restore point corresponds to a synchronous replication, the dialog box displays additional information about the state of the
replication:
• The Sync Data Status eld displays the synchronization status for the replication at the time the restore point was validated.
• A recommendation about whether the destination volume is currently synchronized with the source volume is displayed below the
Sync Data Status eld in green or yellow text.

4 (Live Volume, Storage Center 6.5 and later only) Select the Preserve Live Volume check box to direct IO requests to the secondary
volume without deleting the Live Volume. If the Live Volume manages a replication, Preserve Live Volume must be selected to
preserve the managed replication later in the restore process.
• If Preserve Live Volume is selected, Storage Center directs IO requests to the secondary volume by promoting it to primary. The
Live Volume is not deleted and may be repaired when the original primary Storage Center comes back online. Volume identity is
preserved so that administrator intervention is not required on the servers mapped to the volume. If a replication is managed by
the Live Volume, it moves to follow the newly promoted primary volume. Fewer volume settings are available because the existing
Live Volume settings are used.
• If Preserve Live Volume is not selected, Storage Manager deletes the Live Volume, creates a view volume, and maps it to a server.
During the restore process, the Live Volume is recreated. If a replication is managed by the Live Volume, the managed replication is
removed later during the restore process.
5 In the Name eld, type the name for the recovery volume.
6 Select a server to map the recovery volume to by clicking Change next to the Server label.
• A server is required for each restore point unless the Preserve Live Volume check box is selected.
