Disaster Recovery Setup for 4 node RAC

Hello,

In our environment, trying to setup disk based mirroring of the Production Environment Oracle RAC GI and DB Home binaries into the DR Environment.

Also the ASM of SAN Storage from the production to DR Server will be mirrored across.

Once this is broken, we have to bring up the  RAC on the DR Environment.

Please advise how feasible this solution is.  Will the RAC GI Binaries can be mirrored and brought up ?

In general for the RAC setup in Production , how the similar setup across the DR Environment is setup and maintained.

Please provide me any pointer on this topic.
