Create a mapping file that resides on a VMFS data store and points to the LUN. Although the mapping file has the same 
.vmdk extension as a regular virtual disk file, the mapping file contains only mapping information. The virtual disk data is stored 
directly on the LUN. The mapping file to an RDM is created by using the 

vmkfstools command:

{root@esxi1~]# vmkfstools -z /vmfs/devices/disks/naa.device_id /vmfs/volumes/SvSAN_LocalDisk/SvSAN-

C240M4-01/rawdisk-naa.device_id.vmdk
