Hi Sunil,
This is only a test environment and the storage had ever been changed.
The necessary filesystems for RAC currently are as follows:
/dev/emcpowera /u530/origcrsdata ocfs2
_netdev,datavolume,nointr 0 0
/dev/emcpowerd /u531/mirrcrsdata ocfs2
_netdev,datavolume,nointr 0 0
/dev/emcpowerc /u532/mirrcrsdata ocfs2
_netdev,datavolume,nointr 0 0
/dev/emcpowere /u001/oradata ocfs2
_netdev,datavolume,nointr 0 0
