Would someone please give me some idea how to troubleshoot scsi problems? The CD works fine but the tape drive errors as below, so I tend to suspect the tape driver rather than the scsi, but I am not too sharp on scsi, so need guidance. I though if I stuck with scsi, nothing could go wrong. Apparently that was fuzzy thinking. At work (SONY tape) everything works great. What can be different between scsi tape devices? Don't they all use the same (scsi) commands? Thank you for any help. ---------------------- Forwarded by Bob Pekarske/Tuc/BB1 on 06/09/97 05:10 PM --------------------------- pekarske_bob@burr-brown.com on 06/04/97 12:39:06 AM Please respond to pekarske_bob@burr-brown.com To: freebsd-questions@FreeBSD.ORG cc: pekarske_bob@u2.bbrown.com (bcc: Bob Pekarske/Tuc/BB1) Subject: scsi tape errors I have FreeBSD on an Intel system with an Exabyte SCSI tape. When I try to tar to the tape, I get the following messages: /kernel: st0(aic:4:0): timed out /kernal: st0: bad request, must be between 512 and 1024 /kernel: aic: invalid reselect (idbit=0x10) /kernel: aic at line 2326: identify failed There is some tape action prior to failure. On boot, the device seems to be identified/probed o.k. If I do a second tar, the system reboots. Will someone please help me understand these messages? Or direct me to reference documents? Thank you for any help
