Hi, A while back we bought a Qualstar 20 tape DLT changer to handle tape backups for our lab. Our model does not have a barcode reader. After adding the ch device, FreeBSD (4.1.1-STABLE) sees the changer. It identifys the various slots, drives, etc and appears to report correct status picker, portal, and drive, but it reports <EXCEPT> as the status of all the slots. I got similar results from STCTL under solaris (http://www.cs.pdx.edu/~eric/stctl/). Attempts to move a tape from a slot to a drive fail. I've got CAM_DEBUG in the kernel and I'll have physical access to the system next week so I'd like some suggestions on debugging this system if you have any. Here's some information I have now. From dmesg: ch0 at ahc0 bus 0 target 3 lun 0 ch0: <QUALSTAR TLS-6220 2.09> Removable Changer SCSI-2 device ch0: 3.300MB/s transfers ch0: 20 slots, 1 drive, 1 picker, 1 portal Output from "chio status": # chio status picker 0: slot 0: <EXCEPT> slot 1: <EXCEPT> slot 2: <EXCEPT> slot 3: <EXCEPT> slot 4: <EXCEPT> slot 5: <EXCEPT> slot 6: <EXCEPT> slot 7: <EXCEPT> slot 8: <EXCEPT> slot 9: <EXCEPT> slot 10: <EXCEPT> slot 11: <EXCEPT> slot 12: <EXCEPT> slot 13: <EXCEPT> slot 14: <EXCEPT> slot 15: <EXCEPT> slot 16: <EXCEPT> slot 17: <EXCEPT> slot 18: <EXCEPT> slot 19: <EXCEPT> portal 0: <INEAB,EXENAB,ACCESS> drive 0: <ACCESS> Output from an attempt to load a tape: aero# chio move slot 0 drive 0 chio: /dev/ch0: CHIOMOVE: Invalid argument Oct 6 13:25:25 aero /kernel: (ch0:ahc0:0:3:0): MOVE MEDIUM.
