Hi Karl,
Manually cloning the root pool is difficult. We have a root pool
recovery procedure that you might be able to apply as long as the
systems are identical. I would not attempt this with LiveUpgrade
and manually tweaking.
http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide#Complete_Solaris_ZFS_Root_Pool_Recovery
The problem is that the amount system-specific info stored in the root
pool and any kind of device differences might be insurmountable.
Solaris 10 ZFS/flash archive support is available with patches but not
for the Nevada release.
The ZFS team is working on a split-mirrored-pool feature and that might
be an option for future root pool cloning.
If you're still interested in a manual process, see the steps below
attempted by another community member who moved his root pool to a
larger disk on the same system.
This is probably more than you wanted to know...

# zpool create -f altrpool c1t1d0s0
# zpool set listsnapshots=on rpool
# SNAPNAME=`date +%Y%m%d`
# zfs snapshot -r rpool/r...@$snapname
# zfs list -t snapshot
# zfs send -R rp...@$snapname | zfs recv -vFd altrpool
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk
/dev/rdsk/c1t1d0s0
for x86 do
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t1d0s0
Set the bootfs property on the root pool BE.
# zpool set bootfs=altrpool/ROOT/zfsBE altrpool
# zpool export altrpool
# init 5
remove source disk (c1t0d0s0) and move target disk (c1t1d0s0) to slot0
-insert solaris10 dvd
ok boot cdrom -s
# zpool import altrpool rpool
# init 0
ok boot disk1

I would like to clone the configuration on a v210 with snv_115.
The current pool looks like this:
-bash-3.2$ /usr/sbin/zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror ONLINE 0 0 0
c1t0d0s0 ONLINE 0 0 0
c1t1d0s0 ONLINE 0 0 0
errors: No known data errors
After I run zpool detach rpool c1t1d0s0, how can I remount c1t1d0s0 to /tmp/a
so that I can make the changes I need prior to removing the drive and putting
it into the new v210.
I supose I could lucreate -n new_v210, lumount new_v210, edit what I need to,
luumount new_v210, luactivate new_v210, zpool detach rpool c1t1d0s0 and then
luactivate the original boot environment.
