I first encountered this problem in April, now I'm back to it: http://lists.freebsd.org/pipermail/freebsd-scsi/2008-April/003452.html In short, the system has tape library. The library has worked in the past (http://www.freebsddiary.org/digital-tl891.php) but now it does not. I can see either the tape library or the tape drive. Which I see depends upon the cable configuration. http://www.freebsddiary.org/images/tape-libraries-cables.jpg As shown above, that's how I would expect things to work normally. However, in that configuration, I do not see the tape drive. The cable going down, goes to the computer. If I reconnect that cable to the plug to the left of the terminator, the system can see the DLT drive, but not the tape library. Under 6.3-STABLE FreeBSD, I can see either one device or the other. ch0 at ahc0 bus 0 target 0 lun 0 ch0: Removable Changer SCSI-2 device ch0: 20.000MB/s transfers (10.000MHz, offset 8, 16bit) ch0: 10 slots, 1 drive, 1 picker, 0 portals or sa0 at ahc0 bus 0 target 1 lun 0 sa0: Removable Sequential Access SCSI-2 device sa0: 20.000MB/s transfers (10.000MHz, offset 8, 16bit) acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01 Any ideas?
