Is the storage available on all hosts involved in the VMotion process? In other words, is the storage on host1 that the VM is on be seen on host2 that you're VMotion'ing the VM to?

Yes  and this is only RAW device mapped drives that this happens on.

Is the RDM virtual or physical mode? See this KB that might give an explanation on potential RDM issue:

That is probably the cause, then.  Even though ESX 4.x uses NAA's for most operations, vMotion still uses the LUN # to identify the LUN's from host to host.
