Oracle Solaris 11 includes a powerful Upgrade Feature based on IPS (Image Packaging System)
and ZFS. When Upgrading the Operating System a new Boot Environment is created and updated.
No impact on the currently running System. The new Environment is activated using a reboot. This allows to failback to the old Boot Environment if Applications don't run as expected on the new Solaris Release.
Find more about Upgrading in the Oracle Solaris 11.3 Manual
https://docs.oracle.com/cd/E53394_01/html/E54739/pkgupdate.html#scrolltoc
Upgrading using VDCF
The VDCF Management Framework for Oracle Solaris includes a feature to upgrade multiple Nodes in parallel using one command. The operation to use is "node -c upgrade name=nodeA,nodeB build=targetSRU". This upgrade operation does not only upgrade the OS to a predefined build, it also first checks if enough disk space is available. After a successful OS Upgrade the VDCF Repository is updated with the new Boot Environment and OS Update.
Sample of Upgrading 10 LDoms in parallel
The VDCF Framework is installed in a small LDom running on a SPARC T4-1 Server. The 10 Target LDoms are running Solaris 11.2 on a SPARC T4-2 System. Some of the LDoms host Solaris Zones,
which are also upgraded in parallel.
VDCF uses the Oracle Solaris pkg command with the following options
-C 5 to update the Zones in parallel
--be-name s11.3.3.0.6.0 to set a meaningful BootEnv Name
entire@0.5.11,5.11-0.175.3.3.0.6.0 to select a specific Solaris SRU
