Emulex:

You have to have installed the emulex utilities. Change to directory /usr/sbin/lpfc, and run lputil64 to find the WWN:

root@somehost{/usr/sbin/lpfc}#./lputil64

QLOGIC (qlogic 2200):

You need the qlogic utilities installed aswell. Change to the installation directory:

root@somehost{/}#cd /opt/QLogic_Corporation/drvutil/qla2200

You’ll see some utilities there.

root@somehost{/opt/QLogic_Corporation/drvutil/qla2200}#ls
qldriverop qlfwdmp_readme.txt qlreconfig
qldriverop_readme.txt qlogic_adapters qlreconfig_readme.txt
qlfwdmp qlogic_adapters_readme.txt readme.txt

Next step is to find the control devices of the qlogic cards:

root@somehost{/opt/QLogic_Corporation/drvutil/qla2200}#find /devices -name ‘QLGC*:devctl’
/devices/pci@13c,600000/QLGC,qla@1:devctl
/devices/pci@13d,600000/QLGC,qla@1:devctl
/devices/pci@15c,600000/QLGC,qla@1:devctl
/devices/pci@15d,600000/QLGC,qla@1:devctl

With this information, run the following command of the desired control device:

./qldriverop -d /devices/pci@13c,600000/QLGC,qla@1:devctl -c fcid

And finally go to the /var/adm/messages and take a look:

[..]

As a final note, in order to find the WWN of a JNIC card (old) this is how i managed to find it:

root@somehost{/}#prtconf -vp | grep -i my_wwn_
my_wwn_hi: 10000001
my_wwn_lo: 73011218
my_wwn_hi: 10000001
my_wwn_lo: 73011170

Join together hi+lo and you’ll have the wwn
