RDM get converted to VMDK while migrating between datastores

Hello all!

I have a VM with three LUNs mapped as RDM in virtual mode. The disk for the system has always been a VMDK. I run Exchange on the VM.

When I migrated the VM to a different datastore, the RDMs got converted into VMDKs. Looking into the LUNs afterwards, they were empty.

Does anybody have an explanation for that and perhaps a way to undo thaht?

many thanx & greetings,

Stephan

Just had the same thing happen to me. At first i couldnt work out where all the room on my datastore had gone.

Easily sorted by editting the vm settings to point back to the RDMs and deleting the vmdk files. Still annoying though.
