Any assistance would be greatly appreciated!
Thank you in advance,

-------------------------Customer's problem
statement----------------------------------------
I'm unable to import a mirrored ZFS pool. The system was shut down with
a functional mirrored ZFS pool using c1t0d0s6 and c1t1d0s6. Solaris was
then re-installed from DVD media using c1t0d0 as the root disk. The
root disk was repartitioned during install, which destroyed slice 6
formerly used as a Zpool mirror component. I need to recover data from
the mirrored Zpool using the one remaining mirror.
Based on this behavior, I'm also concerned that a system with a mirrored
ZFS root disk could be difficult to recover. Example: Server X boots
from mirrored zpool "rpool". Server X is shutdown for maintenance, and
1 of the 2 disks in the mirrored Zpool fails when the server is powered
back on. Now the mirrored zpool is unable to be imported and the server
fails to boot. What is the recovery procedure?
# zpool import
pool: local
id: xxxxxxxxxxxxxxx
state: UNAVAIL
status: The pool is formatted using an older on-disk version.
actiion: The pool cannot be imported due to damaged devices or data.
config:
local UNAVAIL insufficient replicas
mirror UNAVAIL corrupted data
c1d0s6 ONLINE
c1t1d0s6 ONLINE
# zpool import -o failmode=continue -f local
cannot import 'local': invalid vdev configuratiion
# zdb -l /dev/rdsk/c1t1d0s6
