Well, today's hardware session made some progress, but not all that
we'd hoped. We got things reconfigured a bit in anticipation of the
arrival of the Emulex (which is what the Thursday downtime is all about):
four of the DZs, and the Sanders DL, are now in a 9-slot backplane in
the expander box (which is back on the system). When the Emulex is in
production, the contents of that backplane will be decommissioned.
There is now a nice substantial open space in the cpu box, and the cable
slot is also much less crammed than it was.
Note that the middle slot of the old 9-slot backplane has the DMA
grant jumper cut, which we remembered after some hassle, and must
have a Plessey DZ sitting in it (they have the jumper internally).
We also took advantage of the downtime to do the recabling for the
drive-A radial cable, and that's where the fun starts. New cable
in and installed, and drive A is misbehaving the same way it did
with the old cable. Very mysterious. Further efforts on this are
very tentatively scheduled for Wednesday.
