Can you vmotion and rdm

What is a Raw Device Mapping? The migration operation fails.

If clustered virtual machines with RDMs MUST be migrated, an approach can be to remove the clustering elements, then migrate individual nodes, and finally rebuild the clustering services at the destination according to what is supported there. This behavior struck me as odd and unexpected, so I started digging in and doing some testing.

I did all my testing on vSphere 4. I tried several times with datastores of various sizes, including a datastore that had less free space than the size of the mapped raw LUN.

Ah, perhaps that was causing part of the problem. When migrating RDM files, It creates a new. We can say it clones the same files at new host. And leave the current source intact. It does not allow virtual machine to read or write instead it uses the new disk. Normally we do not do that either we de-attach the RDM disk from the source VM do not delete it and then migrate the VM, re-attach to disk on VM at the destination host.

This is simple and does not require to create any. While migrating the files you can change the storage type of datastore. In the whole process of migration Virtual Machine Files are untouched only virtual machine registration happens at destination host.
