It took a phone call, name shall remain anonymous.

Two things, one was a side issue.  Side issue first:

Firmware revision was in the 8.xx.xx vicinity, drives were 9GBs

Fortunately, the firmware on our production box was in the 9.56.07
and the drives were 4.2GBs.  I had some spare 4.2GBs.

Power down the new Mod20 took out the 9GB drives out of slot A0.
Put in the 4.2GB drive in slot A0.
Powered up.
The new firmware revision then propagated to all the other drives.
Powered down.
Took out the 4.2GB from slot A0.
Put back the 9GB back in slot A0.
The new firmware revision then propagated to the last drive in A0.
(Of course the original 9GB drive will freak out and do some
serious rebuild time on the Hot Spares, but that can be lived
with.)

Main issue:

Had to go in Maintenance Mode on the Mod20 and change the System
Storage type from A to 2.  

Type A seems to work on MPE if you want to daisy-chain SCSI-A to SCSI-B,
but it seems you need type 2 if you want to use two separate SCSI cards
on the MPE host.
