Recording Reference Numbers
Each HBA ships with a unique address identifier that is stored in flash memory.
Fibre Channel industry standards issue two unique identifiers: WorldWide Port
Name (WWPN) and Node Name (NN), each of which is derived from the HBA’s
IEEE address. Combined, the WWPN and NN create the WorldWide Name
(WWN) which is an 8-byte field that uniquely identifies an HBA on a FC circuit.
The WWN address and serial number are clearly marked on the HBA. Record the
addresses on the lines below for future reference.
Note: The WWN is a static identifier that cannot be changed.
