Here is a dual port HBA

root@linux:~ # lspci | grep -i fibre
06:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02)
06:00.1 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02)

Verifying the WWPN from the HBA

root@linux:~ # cat /sys/class/scsi_host/host0/device/fc_host\:host0/port_name
0x10000000c99f46b4
root@linux:~ # cat /sys/class/scsi_host/host1/device/fc_host\:host1/port_name
0x10000000c99f46b5

The WWPN show above is:
10:00:00:00:c9:9f:46:b4
10:00:00:00:c9:9f:46:b5

Or you can use systool instead of messing with /proc

root@linux:~ # systool -av -c fc_host
