Our issue is that z/VM and the zLinux guests have to be up and the npiv channel logged in before the new NPIV WWPN can be zoned from the SAN side. At least this is my understanding with EMC storage.

I don't believe you'll have to change anything on the Linux guests - as the target WWPN's on the fabric won't change - only the WWPN associated with the virtual device you attach to the Linux guests will. So if you know which virtual devices you'll use - they can zone things so those new WWPNs have access to same SAN as the old. Then you should be able to come up on the new box without changing anything. After you migrate - they can remove the old WWPN's from the zoning. That's my understanding, but my experience is mostly on the z/VM side and using EDEV with NPIV WWPN's.. I assume the same concepts apply to Linux guests directly attaching the stuff..
