Volume Restore Procedures
If DR was activated for multiple replications and/or Live Volumes hosted by a Storage Center pair, the affected volumes can be
restored in a single operation. If DR was activated for a single volume, use the corresponding restore point to restore it.
Restore Failed Volumes for Multiple Restore Points
If multiple volumes hosted by a Storage Center pair failed, you can restore them simultaneously.
Steps
1. Click the Replications & Live Volumes view.
2. Click the Restore Points tab, then click Restore/Restart DR Volumes. The Restore/Restart DR Volumes wizard
appears.
3. Select the source/destination Storage Center pair for which you want to restore failed volumes, then click Next. The wizard
advances to the next page.
4. Read the Restart Warning and Recovery Warning text, modify any settings that are displayed as necessary, then click
Next. The wizard advances to the next page.
5. In the Available Restore Points pane, select the restore points for which you want to restore volumes, then click Next.
The wizard advances to the next page.
6. (Optional) Configure replication settings for each restore point.
a. Select the restore point that you want to modify, then click Edit Settings. The Restore/Restart DR Volumes dialog
box appears.
b. (Storage Center 6.5 and later, Live Volume only) Choose a recovery method.
● If the Recover Live Volume check box is available, select it to repair the Live Volume by reestablishing connectivity
between the original source volume and activated volume. This option must be selected to preserve volume identity.
If the Live Volume manages a replication, this option must be selected to preserve the managed replication. When
selected, the New Source Volume Settings and Replication Settings are not available because the existing Live
Volume settings are used.
● If the Recover Live Volume check box is not available or not selected, the Live Volume is recreated using the New
Source Volume Settings and Replication Settings you specify. Volume identity is lost, and if the Live Volume
manages a replication, the managed replication is removed.
c. (Replication only) If a source volume is being restored:
● Select the Mirror Back Only check box to skip recreating the replication in the original direction and use the DR site
as the source.
● Select the Automatically Deactivate Destination check box to automatically remove server mappings from the
activated volume without requiring administrator intervention. This option is available only if DR has been activated
for the restore point. If this option is selected, IO to the activated volume should be halted before performing the
restore.
d. Modify the New Source Volume Settings as needed. These settings are described in the online help.
e. Modify the Replication Settings as needed. These settings are described in the online help.
f. When you are finished, click OK.
7. When you are done, click Finish.
● Storage Manager restores the replications and/or Live Volumes.
● Use the Recovery Progress tab to monitor the replications and/or Live Volumes.
8. On the Recovery Progress tab, when the restore point message displays Mirror is synced waiting for destination to be
deactivated, halt IO to the destination volumes.
9. Deactivate each destination volume.
a. Select a restore point and click Deactivate Destination. The destination volume is deactivated, the recovered volume
is activated and mapped to the configured server, and the replication direction is reversed so that the recovered volume
becomes the source.
b. Repeat the previous step for each destination volume that must be deactivated.
