Find WWN Address in AIX

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
Device Specific.(Z5)........00010009
Device Specific.(Z6)........00010002
Device Specific.(Z7)........00000000
Device Specific.(Z8)........210000E08B9B4311
Device Specific.(Z9)........ISP
Device Specific.(YL)........U788D.001.KQ00FC0-P1-C5-T1


# lscfg -vl fcs1
fcs1 U788D.001.KQ12FC0-P1-C5-T2 FC Adapter


Network Address.............210100F08BBB4311 <-- 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
Device Specific.(Z5)........00010009
Device Specific.(Z6)........00010002
Device Specific.(Z7)........00000001
Device Specific.(Z8)........210100E08BBB4311
Device Specific.(Z9)........ISP
Device Specific.(YL)........U788D.001.KQ00FC0-P1-C5-T2

Parthiban - Great post! I use this so much to get WWN's for our SAN team that I made it a function and put it in roots .bashrc:

function getwwn { for i in `lsdev | grep fcs | awk '{print $1}'`; do lscfg -vpl $i | grep Network; done }

That should be all one line by the way in case the web page wraps it. The output is sorted in ascending order beginning with fcs0 and looks like this:

Network Address.............10000000C9A5F8FC
Network Address.............10000000C9A5F8FD
Network Address.............210000215EE2A42D
Network Address.............210000215EE2A42F
Network Address.............10000000C9B620D2
Network Address.............10000000C9B620D3
