How to enable NPIV?

I cannot find virtual port WWN and node WWN in /proc/scsi/lpfc820/x.

The procedure I did:

1) In IBM SAN Switch ,create Zone for IBM DS5020 Storage Port WWN and  ESX Server FC HBA WWN

2) Map LUN to ESX Server

3) Create RDM to VM

4) Enable NPIV in VM (e.g. two node WWN and Port WWN)

5) In SAN Switch, create another Zone for VM Port WWN and IBM DS5020 Storage Port

6) Power On VM.

Then login ESXi to check the creation Vport ,but cannot find any Virtual node WWNs and Port WWNs. Also, cannot find any virtual WWN in IBM Switch through name server.

How to create zoing?

Zoning for VM only include virtual Port WWNs and Storage Port WWN? Not need to include virtual Node WWN.

In Storage management software, when defining host, it is necessary to include virtual Port WWN? No need to include virtual node WWN as well?

I am sure that FC HBA and SAN switch support NPIV.

Can anyone help me?

Thanks!
