Thanks for your response guys,
Richardson:
Yes, i already checked NPIV support on HBA's. We are using HP Emulex Lpe1205A adapter.

I did the procedure you type. Also, i mapped a single LUN presented to the host as RDM to the VM.
Maybe I'm not being clear with what exactly we expect from this. Comparing to hyper-v (we have a mix hypervisor environment), we can present directly the same LUN (200 GB for example) to 02 VM's and creat a SQL Cluster. No need to present this 200 GB LUN to the hyper-v host and passtrough to the VM's, mapping is directly to the VMs virtual HBAs.
We expect the same from VMware vpshere, thats why we are trying these generated WWN's on each VM, but im not pretty sure if this is being supported already.
