Thanks so much for your help!
Not knowing, I plugged the outside (on the end) scsi connection into a
AHA-2940 and was able to see the drive (only had one handy) I had put
inside. But later it did something twitchy, like complaining it could no
longer WRITE to the drive, although reading seemed ok. I didn't care so
much, it was just a basic test.
I was hoping the blinkenlights on the outside of the drive carriers would
work, but alas, they don't seem to.

Subject: DEC Storageworks BA356 questions
drive containers each. The fan modules say BA35X-MD 2x which
makes me suspect that I have a pair of DEC Storageworks BA356
enclosures. They are gray in color.
They each have a personality module, apparently both BA35X-MH.
16bit personality modules for wide-SCSI drives - the 8bit version was
BA35X-MG. This means you should have 2 68 pin plugs on there; make sure you
use the one down the side of the module rather than on the end. The end one
was for cascading.
What do the switches do? The personality module
with the
sticker on it that says SHELF 2 does NOT have the switches
set according to the decal on the module-- they are all off,
whereas on the decal, one is advised to turn switches 1-3 on
and leave 4-7 off.
I never had to change the switches on those; typically they were left unless
you were cascading shelves. I can check some -MH modules in the office
tomorrow if you're still stuck then.
The module from the other unit is marked SHELF 1
and is in
fact set the way the decal advises.
You've got a cascaded pair there then.
Are these personality modules in fact RAID
controllers?
Nope, purely personality modules to support 16bit disks.
Or do the SCSI ID numbers assigned by the
enclosure get
passed through to the SCSI connector?
Correct; the SCSI ID is based on shelf number and which port on the host
machine you're plugged into.
Is there any software out there to configure
these units as
to what flavor of RAID to use? E.g. for Windows XP or Red Hat Linux?
No need - it's all hardware based - plug disks into shelf, plug shelf into
host machine and use disks :)
Cheers
