[comp.periphs] Sun shoebox problem.

eho@clarity.Princeton.EDU (Eric Ho) (09/17/89)

I've a 71meg shoebox (Micropolis) hooked to a Sun-3/75 and I think that
someone might have moved it abruptly.  The thing is that the system continued
to work about 30 mins after the move and then for some reason the system
crashed and then couldn't reboot itself.

The strange thing is that when the system reboots, I see this on the console
:- 

	sd: error FFFFFF91 0 0 D

I was expecting to see something like "sd0: ...." or "sd0a: ..." instead of
"sd: ...".  Does anyone knows what this error message means ?

Also, another strange thing is that when I unplug the shoebox from the 3/75
and plug it into a 3/50 instead, it has this error message when it tried to
reboot (with diagnostic switch = NORM) :-

	sd: sense key = 0 error = 0, block = 218628128

Does any knows what these messages mean ?  Again, I was expecting "sd0: ..."
or "sd0a: ...".  Also, the large value of the block number is suspicious.
Is it a drive problem or a controller/scsi interface problem ?

I'm puzzled.  Any ponters will be much appreciated.
