Recovering the shared disk on a Windows VCS cluster
The following procedure is applicable in situations where the configured cluster nodes remain available but the NetBackup catalog, database files, or both on the shared disk have been corrupted or lost.
Check the following conditions before you proceed with this procedure:
The shared storage hardware is restored to a working state, so that the shared disk resource can be brought online with an empty shared directory.
Valid online catalog backups exist.
To recover the shared disk on a Windows cluster that uses VCS
- Clear the faulted NetBackup resource group, disable monitoring, and bring up the shared disk and virtual name resources on a functioning node.
- Ensure that all NetBackup shared disks are assigned the same drive letters that were used when NetBackup was originally installed and configured.
- To reconfigure NetBackup for the cluster, initialize the database by running the following commands in sequence on the active node:
bpclusterutil -ci tpext bpclusterutil -online
- Use the appropriate NetBackup catalog recovery procedure to restore the NetBackup catalog information on the shared disk.
- If the clustered NetBackup server is a media server, verify that the restored vm.conf file contains the correct host-specific MM_SERVER_NAME configuration entry for the active node. If MM_SERVER_NAME is different from the local host name, edit the file and change the server name to the local host name:
MM_SERVER_NAME=<local host name>
- Use NetBackup to restore any data on the shared disks. Details are available on how to perform a restore.
Refer to the NetBackup Backup, Archive, and Restore Getting Started Guide:
- Configure required devices and media and recover the NetBackup catalogs.
- Manually shut down and restart NetBackup on the active node.
- Re-enable monitoring of the NetBackup resource group.
- Verify that the NetBackup server can now be brought online on all configured nodes.
