NetBackup status code: 52
Message: timed out waiting for media manager to mount volume
Explanation: The requested volume was not mounted before the timeout expired. This error can also occur if the volume is a cleaning tape but was not specified as a cleaning tape.
Another possible cause: the last available drive has a mount request for a non-backup (such as a restore). Then a backup that requires the same drive is initiated before the mount completes. This error is due to the drive not being reported as busy until the mount completes.
Recommended Action: Do the following, as appropriate:
Verify that the requested volume is available and an appropriate drive is ready and in the UP state.
If this error occurs during a read operation (restore, duplicate, verify), the drives could be busy. Increase the timeout for the media mount that the NetBackup global attribute specifies, to allow more time to mount and position the media.
Verify that the tape is not a cleaning tape that is configured as a regular volume.
When an Automated Cartridge System controls the robot, verify that the ACSLS system is up.
If it is an initial installation, a procedure is available.
See "Troubleshooting configuration problems" in the NetBackup Troubleshooting Guide.
On Windows, check the Event Viewer Application log for the error messages that indicate why the tape mount did not complete. On UNIX, check the system log.
