Just a thought on the following:
3. Make the LUNS used by ASM for *sanjay* database on Second RAC
environment. This can be done even in Advance to make sure it is visible on
second Environment
How are you going make the target ASM recognize the LUNS? as they were
already used by the source ASM and marked as member? I doubt the target ASM
will be able to pickup these LUNS.
