I've been having some serious problems with my DN3000 lately. Heres the
backgound & scoop....
Configuration:
DN3000, 4 MB memory, 348 MB Maxtor Disk, One-Slot ring controller, ETH-AT
ethernet controller (its our ether gateway) and B & W display, SR 9.7 & 9.5 IX
Problem(s):
I've been having quite a few crashes lately. When I look at the syserr log,
I have messages such as:
crash status - disk controller error (OS/Disk mangler)
crash status - drive timed out before operation completed (OS/disk mangler)
crash status - disk not ready (OS/disk mangler)
crash status - invalid disk address (OS/disk mangler)
I also have one or two messages of the following form:
<insert you favorite date here> disk error
winchester volx=1 daddr=<pick a spot, any spot>
and also two like this:
crash on < your favorite date, again>
crash statis - illegal lock (OS/level 1 process mangler)
I had one like this just a few minutes ago while trying to shutdown (The node
became disconnected from the network for no apparent reason, which has been
happening quite often lately, but thats another story !) and reboot.
Our disk controller has been replaced twice, but it sure doesn't seem to be
doing any good. Anybody seen this behavior ???

Apparently, ESDI controller is very sensitive to static electricity. On some rev of keyboard D-connectors, it does not make a good ground connection and can cause the system to crash. You should ask your service people and findout which rev or revs of keyboard D-connector can cause problem to the system.

You should try and get the latest patch tape from Apollo.
There is a patch (#100) that fixes bad block forwarding problems that
are present on the SR9.7 release of INVOL.
