Description: NDMP jobs hanging with waiting for media when 'ensure backup is first on media' parameter is ticked in 'Target' tab of backup
Symptoms: Jobs hanging on 'waiting for media' when trying to backup multi-volume NDMP backups.
Cause: it is not possible to use the 'ensure backup is first on media' parameter with multi-volume NDMP backups. The problem is that each sub job reads the parameter anew as if it were a completely new job and so while the first volume will be written to a tape that is blank or marked for reuse when the second volume comes to run it will sit permanently on 'no suitable media' or 'waiting for media'.
When writing multi-volume NDMP backups do not use the 'ensure backup is first on media' parameter. If it is necessary to make sure backups write to an empty tape the best solution would be set up a tape group specifically for these jobs where the tape is always blanked for this group. Another way around this be to create separate jobs for the individual volumes with the parameter not set for the second job
