How to find the world-wide name (WWN) of a fibre-channel card in IBM AIX

To find the world-wide name (WWN) or network address of a fibre-channel (FC) card in IBM AIX:

First find the name of your fibre-channel cards:

# lsdev -vp | grep fcs

Then get the WWN (for fcs0 in this example):

# lscfg -vp -l fcs0 | grep "Network Address"

Example:


lscfg -vp -l fcs0 | grep "Network Address"

On my AIX 53, lsdev -vp does not work.

Instead use,

lscfg -vp | grep fcs

or

lsdev -Ccadapter | grep fcs

to find your fibre channel adapter device names.

if you have sdd.

You can use :
datapath query wwpn

You can use lscfg -El fcsX IN old versions.

lscfg -vpl fcs0 for AIX anyversion to see WWN.

Hiya - nice post. Besides just wwn, if you want a lot more info, fcstat command is great (if avalailabe). e.g.

# fcstat fcs0
