After writing about how to patch (or upgrade) a running system playing with a mirrored OpenSolaris SVM, here is a little step-by-step how to on upgrading (or patching, etc.) a live system using the Live Upgrade feature.
Before installing or running Live Upgrade, you are required to install a
limited set of patch revisions. Make sure you have the most recently
updated patch list by consulting sunsolve.sun.com. Search for the info
doc
72099
on the SunSolve web site (you must have a registered Sun support
customer account to be able to view this document).
Note: In the following procedure, we will assume that all we want (and need) to upgrade to is provided via a one large DVD ISO image.
If all seems OK, you must begin to update the current running system
with the appropriate lu packages, i.e. those provided for the targeted
OS revision. You can either use the provided tools:
# /cdrom/cdrom0/Solaris_11/Tools/Installers/liveupgrade20
Or do it yourself:
# pkgrm SUNWluu SUNWlur
# pkgadd -d /cdrom/cdrom0/Solaris_11/Product SUNWlur SUNWluu
Since the current OS is totally installed on the first slice of the
first disk (c1d0s0), and that the slice six (c1d0s6) is exactly the
same size as the first one, we will use it for the second ABE device for
our purpose and create the corresponding Boot Environment.
# lucreate -c snv_38 -n snv_39 -m /:/dev/dsk/c1d0s6:ufs
/* If the snv_38 BE already exists, just create the new one for snv_39. */
# lucreate -n snv_39 -m /:/dev/dsk/c1d0s6:ufs

Verify the correct attribution of the different file systems, in
particular between those which are cloned (required by a Solaris
installation, such as /, /var, /usr, and /opt) and those which
are shared (such as /export).
# lufslist -n snv_38
boot environment name: snv_38
This boot environment is currently active.
This boot environment will be active on next system boot.

You then just need to upgrade the second BE using the installation media of the desired release or revision.
# luupgrade -u -n snv_39 -s /cdrom/cdrom0

environment <snv_39> contains a log of cleanup operations required.
INFORMATION: Review the files listed above. Remember that all of the files
are located on boot environment <snv_39>. Before you activate boot
environment <snv_39>, determine if any additional system maintenance is
required or if additional media of the software distribution must be
installed.
The Solaris upgrade of the boot environment <snv_39> is complete.
Installing failsafe
Failsafe install is complete.
If something went wrong during the upgrade of the new Boot Environment
snv_39, you can always restart with a very fresh one using the
lumake -n snv_39 command. If all went smooth, you can now check and
compare the newly created BE:
# lucompare -t snv_39 -o /tmp/lucompare.snv_39
# lumount -n snv_39
/.alt.snv_39
# mount -p | grep snv_39
/dev/dsk/c1d0s6 - /.alt.snv_39 ufs - no rw,intr,largefiles,logging,xattr,onerror=panic
# luumount -n snv_39

# zpool export datazp
# shutdown -y -g 0 -i 6
Et voilà! After the reboot, you must see something similar to:
# uname -a

#
# cat /etc/release
