Emulex MD21

Rats, I wanted to use an Emulex MD21 from a Sun external SXSI box to hook my
PDP11s Fuji M2246E ESDI drive (that connects to the QBUS via an Emulex QD21)
upto a PC to do an image dump.

The MD21 works OK with a Sun drive (a Micropolis model 1558) & the PC can
verify each block on that, but with the Fuji M2246E hooked up, I get
"unexpected SCSI command failure" from the Adaptec AHA1540CF BIOS when trying
to verify the disk -
host adapter status : 00h - no host adaptor error
target status : 02h - check condition
sense key : 02h - not ready
+sense code : : 22h
+sense code qualifier : 00h

mean anything to anyone? The Fuji 2246E is working happily in the PDP11/83 so
I don't believe the drive is faulty (yet!)

I noticed the MS21 announce itself to the SCSI controller as an "Emulex
MD21/S2".
I wonder if there is specific Sun firmware in it to talk to only Sun approved
ESDI drives?...
