Ok, I ran the command for all three disks, and in all cases it's
unable to unpack the labels...
# /usr/bin/dd if=/dev/rdsk/c14d0 bs=1k iseek=17 count=512 of=front.labels.c14d0
512+0 records in
512+0 records out
# zdb -l front.labels.c14d0
--------------------------------------------
LABEL 0
--------------------------------------------
failed to unpack label 0
--------------------------------------------
LABEL 1
--------------------------------------------
failed to unpack label 1
--------------------------------------------
LABEL 2
--------------------------------------------
failed to unpack label 2
--------------------------------------------
LABEL 3
--------------------------------------------
failed to unpack label 3
The same goes for
# /usr/bin/dd if=/dev/rdsk/c14d0s0 bs=1k iseek=17 count=512
of=front.labels.c14d0s0
If I however remove "iseek=17" it works for c14d0s0, but still not for c14d0...
# /usr/bin/dd if=/dev/rdsk/c14d0s0 bs=1k count=512 of=front.labels.c14d0s0
512+0 records in
512+0 records out
# zdb -l front.labels.c14d0s0
