For QLogic or Emulex adapters, you can find the WWPN in the /proc/scsi/ adapter_type / n directory, where adapter_type is the host adapter type and n is the host adapter number for your card. Your host adapter type can be either qla xxxx for QLogic adapters or lpfc for Emulex adapters.
What is an HBA port?
A host bus adapter (HBA) is a board that resides in a host and contains one or more host ports. A host port is a port on a host bus adapter (HBA) that provides the physical connection to a controller and is used for I/O operations. The adapter ports on the HBA are called host ports.
