Hi everyone,
I just wanted to add the link to the official statement in the vSphere Replication 5.1 / Site Recovery Manager documentation:http://pubs.vmware.com/srm-51/topic/com.vmware.srm.admin.doc/GUID-084C089D-9689-4F34-9A75-8AFB980A725E.html
"vSphere Replication supports RDM devices in virtual mode only, for both the source and target device."
Best regards,
Bjoern
