Mac Mini - RDM - incompatible device backing specified for device

Running a Mac Mini with ESXi 6. Mac has two internal hard drives, one SSD and one HDD.

Created a VM on SSD, trying to add the HDD as a RDM.  Used the following command at the CLI:

vmkfstools -z /vmfs/devices/disks/t10.ATA_____APPLE_HDD_HTS539450B3D344_____________________TNS3495NE4T5NV /vmfs/volumes/datastore1/RDMs/RDM1.vmdk

Tried to add the new vmdk file to an existing VM (with LSI Logic SAS SCSI controller), received error: Incompatible device backing specified for device '0'

Tried to create a new VM (with VMware Paravirtual SCSI controller), received error: Incompatible device backing specified for device '4'

Also tried using the following command to create the pointer file:

vmkfstools -z /vmfs/devices/disks/vml.0100000000202020202020544e5548964897648549843652484150504c4520 /vmfs/volumes/datastore1/RDMs/RDM1.vmdk

Same results.

Any suggestions?

Same problem in ESXi 6.0 and ESXi 6.0 Update 2.  Can anyone else confirm this issue?
