How to wwpn on Red Hat Enterprise Linux AS release 3 (Taroon Update 7)
I am trying to find out the wwpn on a linux server. I tried using the the commands `datapath query wwpn` and `pcmpath query essmap`. Both of them didnt give me any output. Please check below.
[root@lmpmdxx root]# pcmpath query essmap
-bash: pcmpath: command not found
[root@lmpmdxx root]# datapath query wwpn
-bash: datapath: command not found
here is OS version and kernel version of the server.
[root@lmpmd501 proc]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon Update 7)
kernel version is 2.4.21-58.EL
Can some one please tell me how to find out the wwpn on the server.
