Assuming you are running Sun Cluster 3.2, the Sun Cluster Software Installation
Guide for that release has procedures for using Live Upgrade:
http://docs.sun.com/app/docs/doc/819-2970/6n57ljhp4?a=view
If you want to just upgrade Solaris 9 to an update release of Solaris 9, you
can skip the instructions for upgrading Sun Cluster software. But if you are
upgrading to Solaris 10, you also need to upgrade to the Solaris 10 version of
Sun Cluster 3.2.
But if want to upgrade a Sun Cluster 3.1 configuration, unfortunately the 3.1
user documentation does not provide Live Upgrade procedures. The Sun Cluster
Advanced Administration training course has been teaching for several years how
to use Live Upgrade to upgrade software on a cluster except for Sun Cluster
software itself. The training manuals are not available except to students
taking the course, though. If you have a test system available, you might try
following the 3.2 Live Upgrade procedures, skipping the instructions for
upgrading Sun Cluster software. But Live Upgrade wasn't tested by Sun Cluster
engineering with the 3.1 release, so don't try it on a production system unless
you have thoroughly proven on an identical test system how you can safely do
it. And don't try to use Live Upgrade to upgrade Sun Cluster 3.1 software; the
3.1 release is missing code changes that were made to the 3.2 release to make
Live Upgrade of Sun Cluster software succeed.
