SAN 3310 Multiple LUN's Not Visible on Solaris 9 Host

First, thanks to anyone who has a suggestion. I've been searching on
the web for the past 5 hours, reading posts, fiddling with this,
reseting the controllers, all to no avail. Here's the issue.

We have:
Solaris 9 (latest patches) connected to a 3310 array via SCSI. It's
connected on the primary controller, and currently has a single Logical
Drive that is mounted on the host. No problem.

We just got two new disks in and wanted to expand the space on this host
to make use of our two new drives. Great. Popped in the disks, reset
the controller, recognizes the disks. I expanded the Logical Drives
with the two new disks. No problem. The 3310 now shows that the LD is
270GB rather than 135GB. I then created a second partition with the new
space (approximately 135GB) and mapped that to a host LUN on the primary
controller. Just to be safe, I reset the controllers on the array
again. I still see that I have 270GB of space, two partitions, mapped
to two LUNS.

Logical Drive: 0
Partition: 0
Lun: 0

Logical Drive: 0
Partition: 1
Lun: 1

I can see the first partition/LUN with format. It shows up on c1t0d0
however I would expect to see another one for c1t0d1 (to match the
second partition).

I have added extra LUN lines for the sd driver to /kernel/drv/sd.conf
and reconfigured the driver with:

update_drv -f sd.conf ; devfsadm

But that doesn't show me the second partition. Am I just missing
something completely obvious? I've seen some posts about not being able
to see beyond the 'first' lun, but that's usually when you didn't have a
partition on lun 0, which I do.

Thanks to anyone who might have an idea.
cheers
ian
