how to setup NPIV as Cisco9124 directly linked a Emulex HBA N-port

I had a cisco9124 switch and enabled npiv on the switch.
also I had a HBA card, and setup a N-port.
I can find the N-port pwwn number on the cisco9124,
and setup the virtual pwwn to my vsan1.
my question is:
my configuration is correct? can let 9124 directly linked a HBA N-port as NPIV configuration? I think something is wrong. I am no NPV device.
how can let the virtual ports know which actual port manage the virtual ports.
I mean for example:
my fc1/8 port is with 4 virtual ports, how to setup the 4 virtual ports to fc1/8,
or just donot care the fc1/8, just found all the virtual ports and setup the virtual ports luns, then my emulex HBA card will find the luns?
