I have a sun L280 jukebox and a single dlt7000 drive, I want to use both drives for my backups, I have already setup the extra drive in networker and mounted a tape, how can I be sure that when the tape in the dlt7000 is full that the backups in progress don't wait even when the jukebox still has empty tapes. I set target sessions to 8, and parallelism to 4.
