From Oracle's Site:
You can upgrade or patch a system that contains non-global zones. If you have a system that contains non-global zones, Solaris Live Upgrade is the recommended upgrade program or program to add patches. Other upgrade programs might require extensive upgrade time, because the time required to complete the upgrade increases linearly with the number of installed non-global zones. If you are patching a system with Solaris Live Upgrade, you do not have to take the system to single-user mode and you can maximize your system's uptime.

Oracle Recommended update:

The recommended method of proactively applying patches is to use Solaris Live Upgrade. Solaris Live Upgrade consists of a set of tools that enable users to create an alternate boot environment that is a mirror copy of the current boot partition and then patch the newly created boot partition prior to making it live. Once patched, the new boot partition can be booted. The benefits of using Solaris Live Upgrade are the following:

There is decrease in downtime because the only downtime that is needed is the time to boot between the current live partition and the newly patched partition. Patching is not done on the live partition, so the system can continue in production until it is suitable to boot to the newly patched partition.

If problems occur, you can boot back to the original partition. No patchrm operation is needed. Just reactivate the original partition and reboot.

If Solaris Live Upgrade is not applicable to the system being patched, it is recommended that the appropriate patches are downloaded and all requirements are identified, and then the patches can be applied using only patchadd.

Solaris Live Upgrade might not be applicable under the following circumstances:

There are not enough disk resources available to set up an alternate boot partition. Remember that if you are using Solaris Volume Manager, you need extra resources in order to set up a Solaris Volume Manager alternate boot partition.

You are using Veritas Storage Foundation to encapsulate the root disk.

If Solaris Live Upgrade is being used, it can also be used to apply the Recommended Patch Cluster. One caveat is that you must pass the -t option into patchadd using the -O option to luupgrade, for example:

#cd 10_Recommended
#luupgrade -t -n be3 -O -t -s . ./patch_order
The first -t tells luupgrade that you are installing a patch. The second -t is actually being passed to patchadd through the -O option to luupgrade. It instructs patchadd to skip patch dependency verification.
