Dell Replay Manager Version 7.8 Administrator’s Guide

Recover Data from a Remote Storage Center

For each volume you want to recover:

1. In Dell Storage Manager, locate the remote site and select the volume to recover.
2. Click the Replays tab in the right pane.
3. Right-click the Replay to recover and select Create Volume from Snapshot.
4. In the Create Volume from Snapshot dialog box, accept the default, or enter a new name (such as Log Recovery). In the Create Volume from Snapshot you can map to the server by clicking Change.
5. Click OK.
6. The system creates a View Volume and displays the Map Volume to Server dialog box.
7. Select the server to which you want to map the Replay View Volume. If necessary, create a new server and then click Continue.
8. On the server, in Disk Management, right-click and select Rescan Disks.
   This action refreshes the iSCSI bus and make the new volume visible. You may have to rescan more than once.
9. Bring the disk online in Disk Management and assign the appropriate drive letter or mount point to the volume.
10. From a command-line interface (CLI) such as Command Prompt, type the following commands to clear the necessary attributes to make the volume usable. Be sure to replace the text with your drive letter where necessary.

    C:\> DISKPART.EXE 
    DISKPART> SELECT VOL <DRIVE LETTER>
    DISKPART> DETAIL VOL 
    DISKPART> ATT VOL CLEAR READONLY
    DISKPART> ATT VOL CLEAR HIDDEN
    DISKPART> ATT VOL CLEAR SHADOWCOPY
    DISKPART> DETAIL VOL

    The volume is now fully readable and writable and can be used for recovery operations.

11. If the volume is recovered in a Windows Server failover cluster, the Windows IO structure must be reset using PowerShell. To reset the Windows IO structure, use the −ResetSnapshotInfo parameter of the Set−DiskDevice cmdlet available in the Storage Center Command Set for Windows PowerShell (version 6.1 and later). For information on using this cmdlet, refer to the online Storage Center Command Set help.
    NOTE:Resetting the Windows IO structure is necessary only if you also want to make the new volume a cluster resource. You can recover the volume on a node of a cluster without resetting the IO structure and still use it as a non-clustered disk. However, some clustered applications (like SQL Server) cannot use a volume if it is not a clustered disk.
