Hi,

I've got a 4100 just upgraded to 5.1A PK2. It has two external storage
shelves for the disk drives. Each shelf has a separate controller. It
looks like the controllers are isp0 and isp1. All the drives in isp0 are
showing up fine (there are 5 RZ29B older drives in there). In isp1 all but
one (6 of 7) are showing up. isp1 has 4 RZ29B (older drives) showing up
fine, 1 RZ1ED (somewhat new 18 GB) and 2 RZ1FC (brand new 36 GB) showing up
fine. The RZ1ED is the one that is not showing up:

the disk that isn't showing should be the /dev/disk/dsk9c drive (absent from
the above output).
If I go to /dev/disk and issue:
root_at_thor==> cd /dev/disk
root_at_thor==> ls -alF dsk*c

dsk9 is present.
at the >>> prompt if I issue 'show dev' this drive shows up as dkc600 with a
name of RZ2ED (not RZ1ED).
I'm rather a novice with this disk stuff.  In the past whenever we've had
new drives put in I've alway been able to format them with diskconfig and
then work with AdvFS.  I've never had to troubleshoot this sort of problem
so I'm pretty lost.
Any help is most appreciated.
