Vinay,
Adam is right, you should first decide on which protocol to use since there are differences on multipath configurations depending on the protocol you choose.
For FCP:
- On Windows, you should use DSM MPIO from NetApp;
- On VMware ESXi, you should use ESXi native multipath capabilities. Just make sure you use ALUA enabled LUNs and round-robin as the multipath path selection policy.
For VMware, also take a look at this: http://www.netapp.com/us/media/tr-3749.pdf
* there are amenities that should be considered depending on the protocol you use.
Hope this helps.

Pedro Rocha.
