This section explains how to recover LUNs from a failed volume on a filer or a failed filer using SnapMirror. These LUNs contain the snapshots of the databases to be restored.
You can configure SnapMirror to use a destination volume on the same filer or a different, remote filer. Whether the destination volume is on the same filer as the failed volume or a different one, the procedure you follow to recover is largely the same.
To recover Exchange data using a SnapMirror destination volume, complete the following steps.
| 1 |
Identify the destination mirror volume so that you know the volume to mount when you encounter that step. |
| 2 |
Ensure that the filer hosting the SnapMirror destination volumes is online and that the volumes are available and shared through CIFS. For information about creating CIFS shares, see your SnapDrive documentation. For information about general filer administration, see your Data ONTAP System Administration Storage Management Guide. |
| 3 |
Make sure that all databases that are stored on LUNs on the failed volume are dismounted. For information about dismounting stores, see the Microsoft Exchange documentation. |
| 4 |
From the SnapDrive MMC, disconnect the LUNs that resided on the failed volume. Take note of the drive letters that were used for these disks. For information about disconnecting LUNs, see your SnapDrive documentation. Note |
| 5 |
From the SnapDrive MMC, connect to the LUN files in the active file system of the SnapMirror destination volume. Note For information about connecting LUNs, see your SnapDrive documentation. ResultA Single File Snap Restore (SFSR) is automatically performed, using the most recent snapshot (which could have been created by SnapDrive or SnapManager). |
| 6 |
Run SnapManager and use SnapManager Restore to restore the most recent backup for each storage group. For more information about using SnapManager Restore, see Restoring Databases with SnapManager Restore. |
| 7 |
Launch the Outlook client and verify that your data was properly restored and that the Exchange server is operating correctly. |
| 8 |
Perform a SnapManager backup and verification to verify that your restored database is free of physical-level corruption. |
