SUMMARY: Watchdog & forceload errors (SPARCserver 1000E)

Date: Sat Feb 14 1998 - 09:26:11 CST

Hello again,

I got some replies conserning these weird crashes.
The bottomline in this case seems to be that
almost certainly nothing can be done without
having to replace hardware...

The output (see below) is from POST (power-on
self test) and the prompt '0A' refers to board
0 processor A.

This particular configuration has two boards
(slots 0 && 1). Board 0 has two SuperSPARC II
processor modules and 128MB of RAM. Board 1
has only 128MB of RAM.

The fault might be in processor A or in board
0 memory. Swapping memory and replacing
processor modules might help but probably
one would have to change the whole board.

IF this doesn't help - well then you probably
have to do some unwanted spending.

SPARCserver 1000 System Installation & Service
manuals proved to be a bit illuminating but
they didn't actually solve the problem or
help me diagnose the source of the problems.

There is an easy way of getting quite a lot
of diagnostic data out of a SPARCserver 1000E:

Just turn the key switch clockwise from 'Standby'
position to 'Diagnostic' position.

This starts the POST selfdiagnostic program. One
should probably connect a lineprinter to serial
port A of servers board 0 (instead of terminal
that is).

Another important point I learned: If the system
is in unknown state and you wish to enter the
OpenBoot program, just push reset button (under
the front panel), press v and press s.

Anyways, my thanks for answering my question
