This might be a more universal command and may work in other distro’s..I’m not sure. Please note: this is the WWN of the card only, for this particular box I ran the command on, the fiber wasn’t even ran yet and this is showing the card only.

After fiber is ran etc..and SAN has been presented, you can install multipath; multipathing tools. /etc/init.d/multipath start; multipath -ll or -l should show the WWN.
