Recover Cluster Non-quorum Shared Disks with No Node Failures

To recover cluster non-quorum shared disks with no node failures in the cluster

1. Stop the cluster service on the secondary node and disconnect the shared disks from the secondary node.
2. If a non-quorum shared disk is physically damaged, perform the following steps:
   1. Shut down the primary node.
   2. Replace the cluster non-quorum shared disk with new disks.
   3. Have the Cluster Disaster Recovery Requirements readily available for reference. For more information, see the Cluster Disaster Recovery Requirements.
   4. To restore the original disk signature for the shared disk, run one of the following utilities:
      • dumpcfg.exe for Windows 2003 (See the output file created by this utility during the backup.)
      • DiskPart for Windows Server 2008, Windows Server 2008 R2, and Windows Server 2012
   5. Restart the primary node and the cluster services.
   6. Recreate the partitions on the non-quorum shared disk.
   7. Format the partitions according to the Cluster Disaster Recovery Requirements.
3. Run a restore job from the Arcserve Backup machine to restore the data to a non-quorum shared disk. Select the full volume restore to recover all lost non-quorum volumes in the shared disks.
4. When the restore job finishes, use the Cluster Administrator to bring the shared disk back on line.
5. Reconnect the shared disks and restart the cluster service on the secondary node.

Your cluster should now be back online.
