WWPN Determination for IBM Storage version 6.4 is online

For some time I have maintained a document that details how to determine a WWPN for most common examples of  Fibre Channel storage sold by IBM.  This document is really useful when you’re staring at a WWPN being reported by a Fibre Channel switch or device and you’re trying to work out which port on your IBM Storage it comes from.   It’s great for when you’re performing zoning, creating a build document or setting up mirroring between DS8000s.

Version 6.4 is now online and can be found here:


You can also find and download it from slideshare:

One of the changes referenced in the new WWPN determination document is a corner case you might encounter if setting up mirroring from a DS8100 or DS8300 to a new DS8800, but only where the DS8800 has 8 port host adapters and where the mirroring is to the lower four ports of that adapter.   If I have lost you already,  then the following document will not interest you.   However if you need to configure such an environment, check out my document detailing a variation in the way the adapter ID is reported, which you can find here.
