Hello.  I'm trying to help our chemistry department with what appears
to be a broken DN10000.  The machine is not on maintenance so, before we
call up HP, we want to explore all possible avenues of help.  HELP!

This is a DN10000 with one CPU trying to run Domain OS 10.3.
What's happened is that the machine wouldn't boot, but would die in
pg$init with a crash_status of 00270001.  I went over to fiddle with
it and was able to do an ld at the SP prompt and see the disk files as
well as run EX CONFIG and EX CALENDAR.  I ran EX SALVOL with a -v option
(which said it would not write to the disk) and received some "bad addr"
messages.  SALVOL, however, did not finish and I had to eventually hit
the reset button.

From that point on, we got a consistent Self Tests Failed, on Memory Test #5
(slot 7, memory module 0).  The message was 'Unexpected SP bus error
referencing 08000008' and the DN10000 status display has a flashing
5.7.2.0. after the error.  I tried bypassing our UPS (thinking the power
supply might be low) and vacuuming out all the dust bunnies (there were a
lot!).  Nothing helped, however, and after powering back up we got the
same excat message.

Any ideas on what we could try next?

Thanks,
