Hiyah..
I'm not subscribed to the freebsd-SCSI mailing list, so if anyone has any
info about this, it'd be great if you could CC me in... Anyways... Here's
the problem:
I'm using an Intel Pentium II 350mhz based machine, with a Buslogic SCSI
card in it. The machine used to be running the 2.2.x branch, and I've
recently wiped off the drives and have installed the 3.2-19990803-STABLE
release.
For the most part, the machine runs great. However, this is the machine
that runs Amanda for us, and one day, while I was running Amanda, I got
the following error message, right before the machine crashed... Here's a
transript of what exactly happened:
-----------------------

--------------------------
So basically it looks like some part of our SCSI bus is failing
hardcore...
Here is the results of the 'dmesg' command so everyone can see exactly how
this machine's hardware is configured.....

WARNING: / was not properly dismounted
-----
As you can see, this machine has 3 SCSI devices -- 0 and 1 are internal
4GB seagate barracudas, 2 is our external HP tape drive.
So anyways, I am pretty convinced it is either the card, or one of the
SCSI devices, or maybe even a bug in the BusLogic SCSI driver (I doubt it,
but who knows..heheh)? It seems as though something on the SCSI bus reset
itself or something, from what I've seen in the error message.. Could
this be a termination problem? I've doublechecked all of our termination,
and it seems to be OK !?!? ...
If anyone has any suggestions, even on things to try, I'd appreciate it!
FYI -- this particular problem has only happened once. The machine HAS
been working OK since this happened, but I'm convinced it could happen
again...
Like I said, I'm not subscribed to this list, so please CC me in any
response.. I will check back to the mailing list anyways even if I don't
hear anything in e-mail.
Thanks in advance!!!
