Live Partition Mobility using HP XP SAN storage

I have a real problem that I hope someone has experience of. I am setting up an LPM for a client who use HP SAN storage. In the past when I setup an LPM system the second World Wide Name (WWN) for the virtual client adapters were given to the storage team who then zoned and mapped these to same LUNs as the first WWN, simple. However with this client the storage team reckon there is no way they can do this! This is because the only way to zone and map is to see the WWN on the GUI tool and attach that using the same GUI to the LUN! As the second WWN is always invisible until LPM is started I cannot "illuminate it" for the GUI to see.

The HP SAN storage model is XP24000.

I sincerely hope someone out there has experience of this problem.
