If the job has truly completed and the job is prompting for media removal, you can either set up automatic response per the TN Ken references or simply uncheck the eject media box in the job properties. When the job is configured this way, the command is sent to the tape device to eject the media when the backup/verify completes. If the device does not confirm the tape is out (because of fault or by design), then it is up to the operator to confirm the tape is out to complete the job.
