Formerly called an upgrade, a version update moves the cluster to the latest Oracle Solaris Cluster release by updating all packages. By default, the update also updates the Oracle Solaris OS and any other packages to the latest compatible version and SRU.
Depending on your configuration, preparing your cluster for a version update might include the following task:
Update solaris branded failover zones.
During a version update, the scinstall utility or the scinstall –u update command creates a new boot environment (a bootable instance of an image), mounts the boot environment on a mount point that is not being used, updates the bits, and activates the new boot environment. Creating the clone environment initially consumes no additional space and occurs instantaneously. After you perform this update, you must reboot the cluster.
To perform a version update, go to Preparing to Update Oracle Solaris Cluster Software.
