You would think so, I agree. Unfortunately, after talking with many people over time at places like SHARE, etc., there doesn't seem to be. Things like IBM's SAN Volume Controller seem to make things somewhat easier, but not as easy as it should be. (I don't have any personal experience with the SVC, so I could be overly pessimistic here.) I and several other people see a potentially large opportunity for some ISV to provide a SAN/LUN discovery/inventory/management tool to make a lot of things easier, including CPU migrations. Considering how hard IBM pushes customers to upgrade to new CPUs when they're announced, this is a rather large speed bump to run into.
