Whenever I try to access the tape drive I get the following message. Aug 18 23:37:25 Fridmani /kernel: st0(uha0:6:0): ILLEGAL REQUEST csi:10,8,0,0 asc:24,0 Invalid field in CDB field replaceable unit: 2 Aug 18 23:37:25 Fridmani /kernel: st0: Cannot set selected mode I have been able to reproduce the error on a different machine with a different controller. Is this a problem in the SCSI tape driver or a hardware problem. I don't have access to another drive, so I can't say for sure whether it is repeatable in that respect. I can't remember when the drive started giving these errors, but if I go back to the Feb 2 snapshot the drive works fine. I have done some debugging, and have pinpointed it to the Mode Select command. If necessary I can include a copy of the debug traces.
