Recover Data with Arcserve Backup Installed on Mirrored Disks

If the data on the mirrored disk becomes corrupted or inaccessible from any cluster node, but the cluster nodes are undamaged, and Arcserve Backup is installed on the mirrored disk, perform the following procedure to recover your data:

  1. Shut down the cluster.
  2. Replace the damaged mirrored disk, if necessary.
  3. Perform local disaster recovery on the primary cluster node. Ensure that the data on the mirrored disk containing the Arcserve Backup installation is restored.

    Note: See the special considerations in section Active/Passive Configuration.

  4. From the Start menu, select Shut Down to reboot all servers.
