Find WWN Address in AIX

Posted by Parthiban Ponnusamy

Here is the steps to find the WWN Address of Fiber channel Adapter in AIX Server.


First We will find out all the installed FC (Fiber channel) Adapters in AIX Server.


To do, type the following command:


# lsdev -Cc adapter | grep fcs
fcs0 Available 01-10 FC Adapter
fcs1 Available 01-11 FC Adapter


The above output shows all the FC Adapters installed on the AIX server.


Now to Find out the WWN Number (Address) of each Adapter, type the following command:



# lscfg -vl fcs0
fcs0 U788D.001.KQ12FC0-P1-C5-T1 FC Adapter


Network Address.............210000F08B9B4311 <-- WWN Number of FCS1 Adapter
ROS Level and ID............49535020
Device Specific.(Z0)........00040016
Device Specific.(Z1)........01110003
Device Specific.(Z2)........49535020
Device Specific.(Z3)........00002422
Device Specific.(Z4)........000E0002
