Restore the Entire Clustered Nodes and Shared Disk

If the entire clustered setup is corrupted or not functioning, you can recover the entire cluster. Recovering the entire cluster is a two-part process. First you recover individual clustered nodes using BMR. Then you recover the files and folders of the shared disk.

Note: For quorum disks, rebuild the disk using the cluster management console instead of recovering it using the Restore Wizard in Arcserve UDP Agent (Windows).

Follow these steps:

  1. Prepare the BMR image (CD / DVD or USB stick).
  2. Remove all the connections between the node that you want to recover and the shared disks.
  3. Example: Disconnect the fibre channel connection.
  4. Perform a BMR for the cluster node.
  5. Note: For more information on performing a bare metal recovery, see How to Perform a BMR Using a Backup.
  6. The specific node in a cluster is recovered.
  7. Check the status of the recovered node in the cluster management console and ensure that it acts as part of the cluster.
  8. The specific node in a cluster is recovered.
  9. Repeat the steps to recover all the clustered nodes.
  10. All the clustered nodes are recovered. Now recover the shared disk.
  11. Replace the corrupted disk manually and reconfigure the cluster shared disk.
  12. Identify the agent that owns the shared disk and log in to that agent.
  13. Open the Restore Wizard and select Find Files/Folders to Restore.
  14. Note: For more information on restoring the files and folders, see How to Restore Files/Folders.
  15. Select all the files from the Restore Wizard that you want to restore to the original location.
  16. Complete the Restore Wizard configurations and submit the job.
  17. The shared disk is recovered.
  18. Verify the files of the shared disk and ensure the files are recovered.

    19. The entire cluster is recovered.
