Does SVM have the granularity to select specific VM RDMp drives and convert them to VMDK on Specific VMFS's?
Have a VM that has 2 RDMp's,
Want to convert these RDMp's to vmdk's at the same time move to NEW target Luns.
Can this be acconplished with Storage Vmotion (esxi5)?
Can I select specific RDMp and place them on specific NEW vmfs datastores?
Is ther overhead on the conversion? Thinking metadata for the vmfs so the target lun should be a bit larger that source RDMp
any guidence helpful

In ESX 5.0, during the Storage vMotion, virtual mode RDMs can be converted to thick/thin provisioned disks by selecting the appropriate options under the Advanced section of the migration wizard. Physical mode RDMs can only be converted with a cold migration. For more information, see the Migrating RDMs, and a question for RDM Users blog post.

About the VMDK overhead, VMFS-5 volumes will require approximately 970 MB of capacity to be reserved on the VMFS volume plus an additional 1MB for each 100GB of the volume.

As I knew, one way is to run the VMware Converter. It can use the source as your existing virtual machine and the destination as a new virtual machine.
The result is generating a copy of the VM where the RDM is converted to VMDK.
