Restoring a LUN from a Snapshot copy

SnapDrive restores a LUN using the rapid LUN restore feature.

Before you begin

Shut down all resources directly or indirectly dependent on the LUN.
Make sure that the LUN is not being used by the Windows file system or any other process, and that no user has the LUN open in Windows Explorer. Shut down any application that is using the LUN.
Attention: Make sure that the Windows Performance Monitor (perfmon) is not monitoring the LUN.

Note: Make sure that virtual machines, Microsoft Exchange, or any other applications are no longer running on a LUN before you restore that LUN from a Snapshot copy.

Steps

Perform the following actions:
1. In the left MMC pane, select the instance of SnapDrive you want to manage.
2. Double-click Disks to display all available disks.
3. Select the LUN that you want to restore and double-click it to display all the Snapshot copies list.
4. Select the Snapshot copy from which to restore the LUN.
In the menu choices at top of MMC, click Action > Restore Disk.
Note: You can only restore a Snapshot copy that is consistent with the active file system. Inconsistent Snapshot copies are not available for restoration and are grayed out.

The Restore Snapshot Copy panel is displayed.
In the Restore Snapshot Copy panel, click Yes to restore the LUN from the Snapshot copy you selected.
Attention: Do not attempt to manage any Windows cluster resources while the restore is in progress.
