I need guidance in setting up SnapDrive on our Windows 2003 Enterprise x64 servers.  We have two of these servers clustered hosting our SQL 2000 servers.  My question is this:

What is the proper way to install snapdrive on a machine that already has LUNs mapped with the iSCSI initiator?  Should I disconnect the LUN first?  I did read one post on the NOW forums where a guy got hosed by disconnecting the LUN and then installing SnapDrive after someone told him that’s what to do.  He was never able to mount them back. I’m trying to dot all my I’s and cross all my T’s before I dive in here.
