11gR2 RAC DB on HP UX server with ASM

I need one help how to -11gR2 RAC DB on HP UX server with ASM.

 Can any one guide the high level steps for doing this ? I've a 100G DB which is running on 10.2.0.5 on pa risc 11.23 server and unfortunately the 11.23 is not certified so we need to do OS upgrade to 11.31 and presently our DB is running on vendor cluster HP UX but this time we decided not to use vendor clluster to reduce addtiional cost. So we requested SA for 2 servers for buiding a TEST env.

 We need the high level steps and also how to have rac without using vendor cluster?  is it possible to configure 2 node rac if yes how ? what shud we ask to the SA for providing luns ? or lvm ? slvm ? what steps the SA shud perfor and how it will be a shared disk if we dont need vendor cluster...etc etc.
