Restore a Failed Volume for a Single Restore Point
If a single volume failed, you can use the corresponding restore point to restore the volume.
1 Click the Replications & Live Volumes view.
2 Click the Restore Points tab.
3 Right-click the restore point that corresponds to the failed volume, then select Restore/Restart DR Volumes. The Restore/Restart
DR Volumes
dialog box appears.
4 (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.
5 (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.
6 Modify the New Source Volume Settings as needed. These settings are described in the online help.
7 Modify the Replication Settings as needed. These settings are described in the online help.
8 Click OK.
• Storage Manager restores the replication or Live Volume.
• Use the Recovery Progress tab to monitor the replication or Live Volume.
9 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 volume.
10 Deactivate the destination volume by selecting the restore point and clicking Deactivate Destination. The destination volume is
deactivated, the recovered volume is activated and mapped to the congured server, and the replication direction is reversed so that
the recovered volume becomes the source.
Deleting Restore Points
If a replication or Live Volume has been removed or is no longer functioning and you want to remove it permanently, delete the associated
restore point.
Prerequisite
