I have a question regarding a multipath issue.

A server that i'm upgrading from oes2 to oes2sp1 has a minor problem.
Today the server has a HBA card (Fiber channel) with double paths to the SAN. However the server was installed without configuring the multipath demon. So the NSS volume that resides on the SAN only sees 1 path to the SAN. I would like to fix this while i'm upgrading the box and have a window of downtime. So the question is.. how can i reconfigure the NSS volume to point to the new multipath aware path instead of the old (probably something like sdb/sdc)??

Are there any problems with this?
