Hi Bill,
First, the controller initiator must be different betwen the two
controllers, something like 7 for 43p_A and 6 for 43p_B, or you got a
conflict. The same for the local disk with ID's set to 0 (You have two on
the same SCSI bus).
I think you can change the initiator on 43p_B, for example, in
Maintenance startup.
Regarfs,

on 43p_A I set the SCSI ID 0 for the local disk (boot
disk) and ID 3 for the shared disk. the shared disk is
connected to rear panel with a ribbon cable and the
third connector is pluged in to 43p_B which local
disks IDs are set to 0 and 1. I booted up 43p_A and
can see both disks. 43p_B can't be booted up.
I'm wondering if both contrallors on these machines
can sit on one single bus. They both have SCSI ID 7 as
initiators.
