A failover zone is a non-global zone that is configured with the HA for Oracle Solaris Zones data service so that it can be managed by the Oracle Solaris Cluster software. If you have failover zones of brand type solaris configured on the cluster, perform this procedure in conjunction with the procedures for the cluster upgrade method that you use.
After you upgrade the solaris branded zone, failover behavior differs, depending on the version of Oracle Solaris the cluster is running.
On Oracle Solaris 11.2, the last zone boot environment that was booted is first cloned and then activated on the node.
On Oracle Solaris 11.3, the zone is attached using the –x deny-zbe-clone option of the zoneadm attach command. For more information about this option, see the zoneadm(1M) man page.
