It detects them, but sends bad/incorrect commands to it. Also tested on an HP autoloader (model number unknown) and couldn't get cd0 to grok it. >How-To-Repeat: See below. >Fix: The following command shows the correct scsi command to load/unload a tape. x = Source bay y = Destination bay scsi -f /dev/rst0.ctl -s 100 -c "a5 20 0 0 0 x 0 y 0 0 0 0" Bay 1 = Tape Drive Bay 2 = Loader slot 1 Bay 3 = Loader slot 2 Bay n = Loader slot n+1 To load a tape in slot 2 to the drive, the following command works: scsi -f /dev/rst0.ctl -s 100 -c "a5 20 0 0 0 3 0 1 0 0 0 0" To eject the tape into slot 4: scsi -f /dev/rst0.ctl -s 100 -c "a5 20 0 0 0 1 0 5 0 0 0 0" You do get a bunch of odd errors if you try to load a tape into a bay that's already got a tape in it, or one that doesn't exist. Be warned that on the Archive 4586NP attempting to load a tape into position 0 makes the tape drive lockup. (you need to power cycle it to recover) Kevin >Audit-Trail: >Unformatted: Date: Mon, 12 Jan 1998 22:08:07 -0600 (CST) To: FreeBSD-gnats-submit@freebsd.org Subject: Adding documentation for scsi(8) usage with autoloaders Reply-To: toasty@home.dragondata.com X-send-pr-version: 3.2 Kevin Day
