SCSI LUN's on 3000/M400

I am having problems adding certain SCSI peripherals on to the external
SCSI bus 'B' on our 3000/M400.

I currently have one SEAGATE disk on the external bus which works fine:

vmunix: rz8 at asc1 bus 1 target 0 lun 0 (SEAGATE ST410800N 0016)

Attempts to add either of two other SCSI devices result in failure. The
primary indicator is at the boot PROM monitor prompt. I forget the complete
output, the relavent data would be:

(with only one of the "failing devices attached to the B bus")
>>> sho device

DKB100 B/0/0 DISK
           B/0/1
           B/0/2
           B/0/3
           B/0/4
           B/0/5
           B/0/6
           B/0/7

The two failing devices are a Micropolis 10 GB drive and a MaxOptics
TNT-3 Magneto-optical drive. If I boot from this stage the cam system
will give me various messages:

Apr 3 16:18:56 betical vmunix: phase
Apr 3 16:18:56 betical vmunix: cam_logger: CAM_ERROR packet
Apr 3 16:18:56 betical vmunix: cam_logger: bus 1 target 0 lun 4
Apr 3 16:18:56 betical vmunix: sim_err_sm
Apr 3 16:18:56 betical vmunix: Target went to bus free phase
Apr 3 16:18:56 betical vmunix: cam_logger: CAM_ERROR packet
Apr 3 16:18:56 betical vmunix: cam_logger: bus 1 target 0 lun 5
Apr 3 16:18:56 betical vmunix: sm_status
Apr 3 16:18:56 betical vmunix: Invalid status phase

all the way up to lun 7... I also see:

May 3 08:57:58 betical vmunix: sim94_sel
May 3 08:57:58 betical vmunix: Flushing residual bytes from FIFO
May 3 08:57:58 betical vmunix: cam_logger: CAM_ERROR packet
May 3 08:57:58 betical vmunix: cam_logger: bus 1 target 0 lun 0

and

May 8 08:31:39 betical vmunix: tcdsintr
May 8 08:31:39 betical vmunix: TCDS DB bus parity error
May 8 08:31:39 betical vmunix: cam_logger: CAM_ERROR packet
May 8 08:31:39 betical vmunix: cam_logger: bus 1
May 8 08:31:39 betical vmunix: ascintr
May 8 08:31:39 betical vmunix: Bus reset detected
 
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The SEAGATE listed above simply reports LUN 0 ...

(only the seagate 10 GB drive attached)
>>> sho device

DKB100 B/0/0 DISK

and gets mounted just fine.

I have installed another Micropolis disk on our AlphaServer 2100 with no
trouble at all. I suspect I might need a firmware upgrade, (think we are
at V3.2) I am running OSF/1 2.0 right now. Think I could upgrade firmware
without an OS upgrade?

Thanks...
