Recover Cluster Quorum Disks with No Node Failures

To recover cluster quorum disks with no node failures

1. Stop the cluster services on the secondary node.
2. Shut down the secondary node.
3. On the primary node, from the Windows Service Control Manager, set the cluster service startup type to Manual.
4. From the Device Manager View menu, select Show Hidden Devices and disable the Cluster Disk Driver setting.
5. If the cluster quorum disks are physically damaged, perform the following steps:
   1. Shut down the primary node.
   2. Replace the cluster quorum shared disk with new disks.
   3. Start the primary node.

      Note: Have the Cluster Disaster Recovery Requirements readily available for reference.

   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. Recreate and reformat the partitions on the non-quorum shared disk.
6. From the Device Manager View menu, select Show Hidden Devices and enable the Cluster Disk Driver setting.
7. Restore the system state backup. In Arcserve Backup, select System State session and right-click to select the local option.

   The System State Restore Options dialog opens.

   

   Note: If the cluster nodes are Active Directory Servers, you must reboot the primary node into directory restore mode when restoring the system state session.

8. Restart the primary node.
9. If the cluster files are not restored to the quorum disk, run the caclurst.exe utility to load the cluster database from the following:

   %windir%\clusbkup
   

   caclurst.exe is available in the Home directory.

   caclurst /s c:\%SystemRoot%\cARCservelusbkup /q Q:
   

   If this is a remote disaster recovery, copy the caclurst.exe file to the Client Agent for Windows directory.

10. Reboot the primary node.
11. Connect the shared disks to the secondary node.
12. Start the secondary node.
