[net.unix-wizards] SI controller hangs with 9766 drives.

eichelbe@NADC (04/16/85)

	Recently ihnp4!mmm!boone (David Boone) asked if anyone was having
hangs of 9766 drives which were SI controlled.  I am having the same problem
but have been unable to get a message to David Boone via the net for some
reason.  So I am posting this to the general unix-wizards in the
hope that (1) David will see it, and (2) someone can help me too!

	We have a VAX 11/780 with one DEC controlled RM03 and three
9766's (like RM05's) with an SI controller (the controller says it is
a 9400 on the front of it).  We have the exact same hang problem!!!
And by the way, we are under 4.1 BSD, not 4.2.
	We hit the reset on the SI controller and everything starts up
again without a squawk (except about the hang) from the users!
	Any ideas, wizardom?

 Hey, SI, you out there? Listening? Our 780 used to have this problem
(under 4.1 and 4.2) with the 9900. It was finally fixed when our eagle
(drive 0, guess where we boot from?) head crashed and the HDA was
replaced. I know  of a guy with a 750 using whatever SI calls an MBA on
those with the same problems. He has been living with it for a LONG while.
He  found, finally, that if he doesn't EVER, EVER turn off his line-printer
he doesn't have the problem.

 This is either a virus or a hardware bug. Since SI won't admit to a hardware
problem (until the fixes are out) it MUST be a virus, right?

It *must* be a virus, transmitted by netnews!  This *just* happened on our 750
today (with SI 9766's on MBA); hitting RESET on the SI 9400 controller made the
system wake up again (the hp.c driver reread the bad block table, incidentally),
and all took off normally.  Of course, then the other 750 hung in its internet
code, so it wasn't quite as lucky.

ANY INFO on this would be appreciated; it's not serious (yet), but I would
like to know what's going on...
