In the next two or three weeks we will have to move from our current z9 to a
z114 and are trying to look for all of the gotchas involved.
This is supposed to be a pull-push type of change with only the underlying
hardware changing to start.
Our current VM is our first experience with VM. We

I second what Rob said - the WWPN tool is designed for this very situation.
Also, the NPIV definitions need to be carried from the old LPAR to the new
one. Have a look at the WWPN tool (from Resource Link) It should help
preparing the definitions that allow the SAN changes to be made before
Bruce,
There are 2 types of wwpns. The physicals will change when upgrading from
z9 to z114. Starting with z196, we generate physicals instead of using
what is burned into the flash on the card. So next time it will be easier
for physicals.
The NPIV wwpns might stay the same. What you want
In the WWPN tool you will have to specify the CHPIDs in the same order as you
turn on NPIV on the CHPIDs or you will not get the proper results.

No FICON was designed for this ;-)Maybe the FCP folks never anticipated
to swap out 100's of servers in a few hours and expecting it to

Whoever created the Config can run the WWPN Prediction Tool and get you the new
WWPN's in advance.
The tool is on IBM Resource Link and requires information from the
configuration. It's been a while but I think I had to provide the configuration
control number as input to pull the info for a
