How to find fiber HBA WWN - HPUX

Use the commands

ioscan -fnC fc to get the HBA path
fcmsutil [HBA path] to get the full info

Sample output below..and guess what? I have two HBAs installed

How to find fiber HBA WWN - Linux

LINUX: Finding Fiber HBA WWN

Verified on Suse Linux Enterprise Server and CentOS/Redhat

The info is in

/sys/class/scsi_host/hostN/device/fc_host/hostN/port_name

Where “N” is the number of device for your fiber HBAs.

Unfortunately, you may have a large number of listings depending on the different cards (besides fiber HBA) that you have on your system. In my example, I have six listings:


host0
host1
host2
host3
host4
host5

but only two represent a fiber HBA.

So you may have to do some digging. In my case they are


host4
host5

(I have two HBAs installed)

So …

[root@centos63node01 ~]# cat /sys/class/scsi_host/host4/device/fc_host/host4/port_name
0x5001438003af1ffc
[root@centos63node01 ~]# cat /sys/class/scsi_host/host5/device/fc_host/host5/port_name
0x5001438003af1b9e
[root@centos63node01 ~]#

Here’s my shortcut bash command if you don’t want to look around. This command is executed in the/sys/class/scsi_host directory.

[root@centos63node01 scsi_host]# for i in 0 1 2 3 4 5; do cat host$i/device/fc_host/host$i/port_name; done
cat: host0/device/fc_host/host0/port_name: No such file or directory
cat: host1/device/fc_host/host1/port_name: No such file or directory
cat: host2/device/fc_host/host2/port_name: No such file or directory
cat: host3/device/fc_host/host3/port_name: No such file or directory
0x5001438003af1ffc
0x5001438003af1b9e
[root@centos63node01 scsi_host]#
