Fetch WWPN Address

Task 1 : Check how many fiber change adapters are there on the Server with below command

#lsdev -Cc adapter

Example

# lsdev -Cc adapter

ent0 Available 00-00 2-Port 10/100/1000 Base-TX PCI-Express Adapter (14104003)

ent1 Available 00-01 2-Port 10/100/1000 Base-TX PCI-Express Adapter 

ent2 Available 01-00 2-Port 10/100/1000 Base-TX PCI-Express Adapter 

ent3 Available 01-01 2-Port 10/100/1000 Base-TX PCI-Express Adapter 

ent4 Available EtherChannel / IEEE 802.3ad Link Aggregation

ent5 Available EtherChannel / IEEE 802.3ad Link Aggregation

fcs0 Available 02-00 8Gb PCI Express Dual Port FC Adapter 

fcs1 Available 02-01 8Gb PCI Express Dual Port FC Adapter 

fcs2 Available 04-00 8Gb PCI Express Dual Port FC Adapter 

fcs3 Available 04-01 8Gb PCI Express Dual Port FC Adapter 

sissas0 Available 03-00 PCI Express x8 Ext Dual-x4 3Gb SAS Adapter

vsa0 Available LPAR Virtual Serial Adapter

Alternatively you can run below command to grep  fiber channel adapter fcs on the system

#lsdev -Cc adapter |grep fcs

fcs0 Available 

fcs1 Available 

fcs2 Available 

fcs3 Available 

From above we can conclude that we have two fiber channel adapters or HBA cards fcs0 , fcs1, fc2 and fc3.

Task 2 : Locate “Network Address” and it’s correspong numeric value means “WWPN Address” on the configuration details of each fcs adapters as below in blue color.

# lscfg -vl fcs0

Device Specific.(ZM)........3

Network Address.............10000000C9B84414

ROS Level and ID............02781174

Now let see the configuration details of fcs1

Alternatively you can run the below command to grep for “Network Address” on each fiber 

channel adapter fcs to get “WWPN Address”

#lscfg -vl fcs0 | grep "Network Address"

Network Address.............10000000C9B84414

Sort Script to get it all at once - 

for i in $(lsdev -Cc adapter |grep fcs|cut -d" " -f1); do echo $i;lscfg -vl $i|grep -i network;done
