Site Recovery Manager 6.5.1 does not support the protection of virtual machines that are configured with multiple-CPU vSphere Fault Tolerance (FT). Site Recovery Manager 6.5.1 supports the protection of virtual machines with uni-processor vSphere FT, but deactivates uni-processor vSphere FT on the virtual machines on the recovery site after a recovery.
If you use multi-CPU vSphere FT on virtual machines, Site Recovery Manager does not deactivate vSphere FT on the recovered virtual machines and powering on those virtual machines fails. You must manually deactivate vSphere FT on the recovered virtual machines by removing FT properties and running the recovery plan again.
If you use uni-processor vSphere FT on virtual machines, you must configure the virtual machines on the protected site so that Site Recovery Manager can deactivate vSphere FT after a recovery. For information about how to configure virtual machines for uni-processor vSphere FT on the protected site, see http://kb.vmware.com/kb/2109813.
