Thanks for reply . I am new in this configuration. I
checked the links provided in earlier email chain. But I am still not clear
the file where I will have to change the WWPN number .
Assuming you want to change paths to LUNs to use a different target
WWPNs on a Linux, that was already installed and is currently running,
then the slides
"LUN Management with ZFCP: SLES/RHEL Post-Installation"
would apply.
You use tools with SLES to remove paths with the old WWPN and add paths
with the new WWPN.
You edit text files with RHEL.
More information for such distro specific information is in the distro
documentation referred to at the bottom half of slide "More Information".
Where appropriate, IBM also refers to distro documentation in the zfcp
chapter of the book "Device Drivers, Features, and Commands".

We are using SUSE 11.2 z/Linux system with FCP channels. There are issues
with one host that WWPN being dropped .
So, now we want to use different WWPN number for this host and bring up
again.
2) Somewhere in z/Linux kernel. I am not sure the exact location
Can anybody help me making this WWPN changes in z/Linux kernel .
Linux configuration only deals with storage target WWPNs.
Pointers are in a presentation I referred to earlier:
