Sun Cluster 3.2 Release Notes for Solaris OS

Live Upgrade

The Live Upgrade method can now be used with Sun Cluster software. This method reduces system downtime of a node during upgrade as well as unnecessary reboots, therefore lowering the required maintenance window where the service is at risk.

At the time of publication, Live Upgrade can be used only if your Sun Cluster installation uses Solaris Volume Manager for managing the storage or disk groups. Live Upgrade does not currently support VxVM. See Upgrade for more information.

Any Live Upgrade from Solaris 8 to Solaris 9 requires SVM patch 116669-18 to be applied before rebooting from the alternate root.
