I woke up on Xmas morning to find my Ultra 30 had crashed. I tried to
reboot but it got a little way into loading the O/S and hung. Another try
produced the following messages very early in the boot process:
WARNING:/pci@1f,4000/scsi@3 (glm0):
SCSI bus DATA IN phase parity error
WARNING:/pci@1f,4000/scsi@3 (glm0):
Target 0 reducing sync. transfer rate
and the boot halted soon after. After a couple more tries it did boot.
I'm wandering if the error is in the scsi system or just the disk. The
actual crash seems to have happened when the system tried to mount another
disk in order to perform a backup. I'm still getting these problems with
that disk removed (and they first occurred, according to the log, at a time
when the 2nd disk wasn't involved). I have tried the 2nd disk with another
machine with no problem.
I ran test-all at ok prompt and got no errors. However, whatever the error
is it seems to be intermittent, since the machine did boot once.
I'd be grateful if someone could tell me which component is at fault (or at
least most likely to be at fault). I just don't know from looking at the
log entries. These follow for info.
Many thanks,
Paul

at this point, everything still apparently running ok and I was unaware of
any problem

the mount is the attempt to mount the backup disk
after this, there's another 60 lines much like the one above, then the
system goes down
finally, here's one of the boot attempt mesages:
