Hello Expert,

We have to perform migration for our RAC database to new SAN that is at new data centre. Since OS is IBM AIX, we can take backup from mksysb for VG and and storage will migrate data from OLD SAN to NEW SAN.

But even we restore VG and SAN data but since our old SAN is emc and new SAN is hitachi, so disk path for all the asm disk group will be changed.

So is there will be any way to rename this disk path for disk group..

Hello - I don't think changing the disc path is really possible. Think about the paths embedded in (for example) your profile.xml files and various OCR keys.
I would create a new cluster (using Grid Infrastructure 11.2.0.3 of course) at the new data centre, and duplicate the database onto it.
