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 -C | grep fcs

Then get the WWN:

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

Example:

# lsdev -C| grep fcs

fcs0            Available 06-08         FC Adapter
fcs1            Available 06-09         FC Adapter
fcs2            Available 08-08         FC Adapter
fcs3            Available 08-09         FC Adapter
fcs4            Available 0C-08         FC Adapter
fcs5            Available 0C-09         FC Adapter
fcs6            Available 0D-08         FC Adapter
fcs7            Available 0D-09         FC Adapter


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

# lscfg -vp -l fcs0 | grep "Network Address"
        Network Address.............10000000C9780B7A

# lscfg -vp -l fcs1 | grep "Network Address"
        Network Address.............10000000C9780B7B
