I had another silly question about your autoloader implementation. How do
you differentiate between unloading a tape and ejecting the entire
magazine? Is this by sending the Unload command to LUN 0 to unload a tape
and sending the command to LUN 1 to unload the entire magazine?

Hi Michael,

Yes. Our DAT autoloader has a single SCSI port. LUN 0 is the tape drive and
LUN 1 is the media changer.

We have implemented magazine eject using the SSC Unload command directed to
LUN 1 (the media change) This is obviously not per standards hence my query
about adding some standard method of ejecting magazines via a SCSI command.
