[comp.sys.next] scsi and upgrade

I just upgraded to an 040/105 meg from a 030/accelerator drive. That
went smoothly but I got somewhat strange behavior when I re-connected
our external drive - an adaptec ACB-5500 SCSI-ST506 controller hooked
to an ST506 Maxtor. The arrangement worked fine on our 030 but not on
040.  When the 040 boots it finds the drive at scsi address 2 (target
2 - logical unit 0), retrieves its label, and mounts it. Fine.
However, it proceeds to look for additional logical units at target 2
(logical unit 1, logical unit 2, ...). It of course fails to find
labels for these phantom logical units and asks to initialize them
when I log in.  Once past these requests, everything is fine, the
maxtor is mounted.  But, regardless of how i respond to this
initialization request, the same scenario ensues next time i boot the
machine.  Has something changed in the way SCSI is handled, should
something be changed to avoid this behavior. I am presently
reformatting the maxtor for other reasons, and a new label may do the
trick, but if anyone has an idea as to what is happening I would like
to know.
