There are two parts to your question - which may or may not be important
to you:

a) what SunCluster configurations are supported by Sun?

b) what security modifications can I made if I don't care about support?

There are no secured configurations of SC2.2 or SC3.0 available today
which are supported. I can say that this is going to change - but can't
give any specifics yet as legal doesn't let us talk about futures.

That being said I'm not going to go into details on securing SC2.2 or
SC3.0 except to say that both products will break if hardened with the
default JASS 'secure.driver'. Please don't run JASS (or any other
hardening tool) on a SunCluster without understanding your support
issues and being willing/able to deal with the problems that come up as
a result of the hardening.
