Each WWN is an 8-byte number derived from an IEEE OUI (for the first 3 bytes) and vendor-supplied information (for the rest) ... quote from wiki

To get your wwn at your Solaris machine, you can use this command

bash> prtpicl -v | grep wwn
:node-wwn      50  01  04  f0  00  5f  0a  85
:port-wwn      50  01  04  f0  00  5f  0a  83
:node-wwn    50  06  0e  80  04  2a  b0  04

or

bash> luxadm -e port
/devices/ssm@0,0/pci@18,700000/SUNW,qlc@2/fp@0,0:devctl            CONNECTED
/devices/ssm@0,0/pci@18,700000/SUNW,qlc@1/fp@0,0:devctl            CONNECTED
/devices/ssm@0,0/pci@18,600000/fibre-channel@1/fp@0,0:devctl       CONNECTED
/devices/ssm@0,0/pci@18,700000/SUNW,qlc@2,1/fp@0,0:devctl          NOT CONNECTED
/devices/ssm@0,0/pci@18,700000/SUNW,qlc@1,1/fp@0,0:devctl          NOT CONNECTED

And then grab one of the luxadm output

bash> luxadm -e dump_map /devices/ssm@0,0/pci@18,700000/SUNW,qlc@2/fp@0,0:devctl
