Post output from following.

pvdisplay -v /dev/rdsk/c29t0d0

vgdisplay -v /dev/vg00

ioscan -fnH 1/0/2/1/0.2.3.0

vgchange -a y /dev/vg00

(BTW, this is one reason to keep /dev/vg00 simple, e.g. very few disks only enough to support OS)

Tim,

attached de output.

I saw now strange things "NO_HW" for de new disks ?!

some other info:
I'm migrating from XP1024 to XP24000
with mirroring (by pvg group name).

All disks c4/c11 & c8/c16 are old one from XP-A and XP-B
and disks c25/c29 are new one XP-C

I need min 4 disks for 1 mirror (fact)

I just created a 3th mirror on new disks

what I now think is that there was already a 3th mirror but broken due missing disk.

output vgcfgrestore -n vg00 -l shows 24 (old) disks and

Tim,

NO_HW in "ioscan -fnH 1/0/2/1/0.2.3.0"
is odd.

one part of that output is:

target 208 1/0/2/1/0.2.3.0.0.15 tgt NO_HW DEVICE
disk 412 1/0/2/1/0.2.3.0.0.15.0 sdisk NO_HW DEVICE HP DISK-SUBSYSTEM
/dev/dsk/c29t15d0 /dev/rdsk/c29t15d0

but when I do "ioscan -fn | grep 1/0/2/1/0.2.3.0.0.15" I got CLAIMED.

# ioscan -fn | grep 1/0/2/1/0.2.3.0.0.15
target 208 1/0/2/1/0.2.3.0.0.15 tgt CLAIMED DEVICE
disk 412 1/0/2/1/0.2.3.0.0.15.0 sdisk CLAIMED DEVICE HP DISK-SUBSYSTEM

I think missing c4t0d6 & c4t8d7 is the problem?
