Ah ... now that you say this I do recall going through the same with our SAN folks as well.. argh. I don't know enough about storage and SAN fabrics to know if there is a way to 'prefill' without the channel being logged in.. it did not sound like it, but I always wondered.
Sorry - I guess it doesn't really help you.. as far as I know - you cannot make use of any tool to import WWPN's so that they are used for NPIV assignments on a new z box. I'd love to be wrong about this though...
