NetBackup status code: 4273
Message: Unable to lock the backup or restore host for virtual machine snapshot operations
Explanation: NetBackup was configured to serialize the virtual machine snapshot operations on the backup or restore host. However, NetBackup was unable to acquire the lock that controls snapshot serialization within the allowed time.
Recommended Action: Restart the backup job when no other virtual machine snapshot operations are in process. If NetBackup cannot acquire the lock frequently, adjust the NetBackup job configuration as necessary to allow the virtual machine snapshots to run at different times or to run on different hosts. Alternatively, reconfigure NetBackup so that the snapshot serialization is not required.
