Ok, I've been getting periodic bad request errors on a scsi drive in a machine here. The drive is a conner drive, id's to: "CONNER CTMS 3200 7.00" type 1 removable SCSI 2 on bootup. These errors occur when I try to do a dump (and as far as I've seen so far, only happen when I do a remote dump). From reading the archives I've seen that I need to enable the scsidebug stuff for any chance of getting some help on this, so I'll be sticking the results from that below. Glancing through the logs that I got from this, from my limited knowledge I'm guessing that the error is this: Apr 20 13:39:39 vision /kernel: st0(ahc0:2:0): Apr 20 13:39:39 vision /kernel: ststrategy st0(ahc0:2:0): 1 bytes @ blk0 Apr 20 13:39:39 vision /kernel: st0: bad request, must be between 5 and 65536 Looking back in the logs where it was succeeding, the lines looked more like this: Apr 20 13:39:36 vision /kernel: st0(ahc0:2:0): ststart st0(ahc0:2:0): Apr 20 13:39:36 vision /kernel: ststrategy st0(ahc0:2:0): 8192 bytes @ blk20176 Apr 20 13:39:36 vision /kernel: st0(ahc0:2:0): ststart st0(ahc0:2:0): scsi_cmd I'm attaching everything that seems to have happened in the log from where the login for the dump occurred below this. If anyone has any ideas, I'd appreciate hearing from them.
