Michael Smith stands accused of saying: > Jul 25 00:03:59 borax /kernel: sd0(uha0:0:0): host adapter code inconsistency ... > This is the first time I've had this crash, although the inconsistency > messages have been piling up ever since 2.0.5 (one of the last ALPHAS) was > installed. Or perhaps more accurately since I've been tinkering with scsi(8). (I can't be sure of this, but I am reasonably; big fingers 8) So, a new variation on the question : what's wrong with this : scsi -f /dev/rsd0.ctl -c "0 0 0 0 0 0" It's a Test Unit Ready command; it neither sends nor returns data, so I'm not specifying any. Results vary depending on what I do before and after it. In what we can pretend is an 'idle' state, I get no output. If I run an Inquiry command (as per the scsi(8) manpage) after it : scsi -f /dev/rsd0.ctl -c "12 0 0 0 64 0" -i 64 "s8 z8 z16 z14" I get : SCIOCCOMMAND ioctl: Command accepted. return status 4 (Unknown return status)Command out (6 of 6): 12 00 00 00 64 00 Data in (0 of 64): No sense sent. SEAGATE ST11200N 9390000666316 and an inconsistency message from the kernel. I get the same result from the CDrom (Matsushita CR-503), but oddly _not_ from either the Micropolis 4110 or my TDC-3660. (Speaking of which, how do I take the SCSI-2 version of the '3600 off the rogue list?) I'm presuming 'difference of opinion' between the SCSI interface in the four devices, but obviously I'm doing something wrong myself. A study of scsi_base.c didn't reveal anything special about the way in which Test Unit Ready is handled, so I'm at a little of a loss at this point.
