BT930 + old scsi disk

BT930 + old scsi disk

[Roeland Th. Jansen]

hi *


I have a BT930 controller; works fine for all scsi disks I have ..
except one..


there is one disk that for the second time has killed the system.


First time I was not at the system when it happened. This time I was.

I heard the following sound (yep, technical ahum) :

click
downspin....
click
upspin......

it was maybe only 3 seconds. but the system froze completely; numlock
leds etc were ok, but magic sysrq didn't work (??)

also, no way I could remotely log onto the system anymore.

At this point, as it's a datadisk, I have taken it off the scsi bus to
prevent further bad things to happen.

unfortunately, there was nothing regarding the scsi controller or disk
in the log.


any ideas what I could do to help preventing this ? (seems somewhere a
bug in the kernel/bt930 ?)

This is almost always a power related problem or drive failure problem, 
not a kernel problem.  The fact that your machine hard locked at the same 
time would make me thing it's your power supply about to go out or that 
you weren't on a battery backup and you got a bad enough brown out to 
cause the machine to loose enough power to lock up and the drive to spin 
down.
