About This Task

Restoring Program Files for Virtual Server When Registry Keys Are Merged

If the additional setting nDisableGalaxyMerge is enabled before starting the full restore of primary node, the registry keys on a primary node are merged during the full system restore. As a result, the following resources are restored during the full system restore:

  • The CommVault Communications Service (GxCVD)
  • CommVault Client Event Manager (GxEvMgrC) cluster

The program files are required to start and run these resources.

Restoring Program Files for Virtual Server When Registry Keys Are Not Merged

If the additional setting nDisableGalaxyMerge is not enabled before starting the full restore of primary node, the registry keys on a primary node are not merged during the Full System Restore.

Procedure

When registry keys are merged, restore the virtual server to the physical node that owns the virtual disk as follows:

  1. Select all the virtual disk data and restore it.
  2. Restore only the program files in order to get the services started. Then restore the rest of the data using the virtual server's File System Agent.

When registry keys are not merged, restore the program files for a virtual server as follows:

  1. Uninstall all Agents from the virtual server.
  2. Re-install File System iDataAgent and all other required Agents on the virtual server
  3. Restore the virtual server's data using the File System Agent.

What To Do Next

For authoritative restores, do the following:

  1. Enter Y (yes) for the following message:

    Full iDataAgent Restore job completed. Do you want to reboot?

  2. Enter Y (yes) for the following message:

    New Hardware found. Windows has finished installing new devices.... Do you want to restart your computer now?

  3. Restart the computer.
  4. After the computer restarts, from a command prompt, navigate to <Install Directory>\base folder and enter the following command :

    authorutil.exe -cluster

    This command will stop the cluster services on all the nodes, replicate the cluster database information on all the nodes and then restart the services.
