Scott:

What else besides the HPIB card is hanging off the channel adapter card?
Is a device adapter card containing disk drives also attached to the same
CA card that the HPIB card is attached to?  If so, is the corrupted data
base at least partially on any of those drives?  You can get the hardware
layout via SYSGEN or IOMAP.PRVXL.TELESUP (or is it IOMAP.MPEXL.TELESUP?).

It sounds like (and I'm no hardware expert) a channel adapter card is
getting ready to call it a day.  You *did* say that you swapped out the
HPIB card and everything booted up OK; however, since no disk devices are
on that card, it doesn't seem logical that the "bad" HPIB card would cause
corruption in a data base or any other files.  On the other hand, if the
channel adapter card is heading South, then the CA card may be causing data
corruption.

By all means, do the FSCHECK you suggested.  Make sure no one else is on
the system; otherwise, you'll get false errors from FSCHECK.  The "CA ALL"
command in FSCHECK is what you want to use.  Also, did Predictive log any
errors?  Have you noticed an unusual amount of Type 111 (I/O) errors in
your system log files?

Just a few random thoughts, Scott!!  Perhaps someone who is more hardware
savvy can chime in here with a more knowledgeable answer.  Best of luck!!!
