IBM Storage WWPN Determination Guide version 6.5

I have updated my IBM Storage WWPN Determination Guide to version 6.5.
You can find the updated guide on IBM Techdocs here.

The main change is that new DS8800s are now presenting slightly different WWPNs, so I added three new pages to describe the changes.

If this guide is new to you, its purpose it to let you take a WWPN and decode it so you can work out not only which type of storage that WWPN came from, but the actual port on that storage.   People doing implementation services, problem determination, storage zoning and day to day configuration maintenance will get a lot of use out of this document.   If you think there is an area that could be improved or products you would like added, please let me know.

It is also important to point out that IBM Storage uses persistent WWPN, which means if a host adapter in an IBM Storage device has to be replaced, it will always present the same WWPNs as the old adapter.  This means no changes to zoning are needed after a hardware failure.

I also host the book on slideshare, so you can also view and download it from there:
