RE: 9I RAC corporate standard.

I couldn't agree more, after the pains of an initial install (i.e. steep learning curve),
I was able to create/re-create a test environment in 1-2 days. That included moving hardware around,
setting up the SAN, installing the O/S, patching it, installing 9.2.0.1 rac, then patching that to 9.2.0.4, and
finally copy a database from my production system to the new test platform.

9iRAC on Tru64 is a breeze. And Tru64 is True Cluster File System. One of the diminishing breed of people still upgrading databases on Tru64 !
