CAM will probably work pretty much like the old SCSI layer with this device. Generally, if you've got a tape changer, it will show up as two devices. One will be the changer device, and the other will be the tape drive. I've got an Exabyte 10i here that shows up like that. The easiest thing to do is just put both ch0 and sa0 in your kernel and see what shows up. :) As for whether the tapes will automatically unload, that really depends on how the drive operates. CAM doesn't (and the old SCSI layer didn't either) automatically unload tapes. You've got to do a mt offline or mt rewoffl to make that happen. (unless the drive automatically does it) Ken -- Kenneth Merry ken@plutotech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
