CSV Timeout in Minutes

This parameter applies to backups of the virtual machines that are configured in a Microsoft Cluster that uses cluster shared volumes (CSV). The timeout determines how many minutes the backup job waits, in case another node in the cluster is backing up the same shared volume that this backup requires.

The default is 0 (no wait). If you do not want NetBackup to wait for the shared volume to be released by another backup, accept the default. If another node in the cluster is backing up a shared volume that this backup requires, the backup fails with status 156.

The appropriate value for this timeout parameter depends on following factors:

The average backup job duration for the virtual machines that reside on the same CSV. The duration depends on the size of the virtual machines and the I/O speed.
The number of virtual machines on the same CSV.

More information is available on NetBackup support for the virtual machines that use CSVs.
