My original query was:
>I've got an HP 97548S SCSI drive which I'm trying to move from a
>SparcStation-1 to a SparcStation-10 which keeps saying "H*ll no,
>I won't go!"
and the symptoms were that when the HP was plugged into the Sparc-10's
SCSI bus, it caused problems even when a different device was being
accessed.
Well, the votes are in, and there are several, mostly non-conflicting
conclusions:
1) It's probably a cable problem. The high-speed, synchronous
SCSI on the Sparc-10 is more demanding of cables than that of
a Sparc-1's SCSI. This is probably it; the cable on the HP
is 2 meters long and of uncertain shielding.
2) It might be a termination problem. Several people said that
the Sparc-10's SCSI bus needed to be *actively* terminated
(but nobody suggested specific vendors!). I have my doubts,
since the CD-ROM is passively terminated and works just fine.
3) It might be a firmware problem. Steve Holmes gave the best
summary of this (sjh@math.purdue.edu):
>We just had similar problems. Things to check: make sure the PROM
>revision is 103 or 206. Other numbers won't work reliably on the
>HP97548. There is a B series and a C series at least. Our PROMS say
>C2SUB206 (or will when the new ones arrive tomorrow!). Look at left
>side of the drive (from the front view) inside near the bottom there
>should be a PROM standing up facing you hiding behind a part of the
>chassis. It should be labeled.
So how did I cure the problem? I gave up! The right cable was not
available (grr - we now have *three* different SCSI connectors!),
and still don't know where to get an active terminator, and getting
the right PROMs could take weeks, so the disk stays with the Sparc-1
(for now). Fortunately, this shouldn't be a problem for the owners
of either the new or old workstations.
