A standard upgrade upgrades a cluster to a new release and upgrades the Oracle Solaris OS to the latest compatible version. You do not need to place the cluster in noncluster mode before performing this upgrade because the upgrade always occurs in the new boot environment (BE) and the existing BE remains unchanged. You can specify a name for the new BE or you can use the auto-generated name. All cluster nodes must be rebooted into the upgraded BE at the same time.
Any time you upgrade the Oracle Solaris Cluster software, by default you also upgrade the data services and Geographic Edition software. However, if you want to upgrade the data services separately, see Overview of the Installation and Configuration Process in Oracle Solaris Cluster Data Services Planning and Administration Guide . If you want to upgrade Oracle Solaris Cluster Geographic Edition separately, see the Oracle Solaris Cluster Geographic Edition Installation and Configuration Guide .
For complete instructions on performing a standard upgrade, see Chapter 3, Performing a Standard Upgrade.
The cluster outage is limited to the amount of time that is needed to reboot all cluster nodes into the upgraded BE.
