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.
• Click Advanced Mapping to congure LUN settings, restrict mapping paths, or present the volume as read-only.
7. Choose which snapshot will be used for the activated volume.
• If Preserve Live Volume is not available or not selected, use the current state of the volume by selecting Use Active
Snapshot, or select a frozen snapshot by clicking Change next to Snapshot. By default, the last frozen snapshot is used.
• If Preserve Live Volume is selected, the last frozen snapshot is used unless Use Active Snapshot is selected.
NOTE: For high consistency mode synchronous replications that are current, the Use Active Snapshot check box
is automatically selected.
8. (Optional) If Preserve Live Volume is not available or not selected, click Change next to Snapshot Prole List to specify which
snapshot proles will be associated with the activated volume.
