BCV  - Business Continuity  Volumes
HVE  - Hyper Volume Extension (a LUN, a portion of a disk or disks that are
presented as a "disk/LUN" to an OS, or are used for BCV or SRDF volumes)
SRDF - Syncronous Remote Data Faclity.  The technology of either sync or
async'ing data between EMC disk frames, normally residing at remote
locations.

	          SRDF Link

    SRDF copies blocks as they change, from Primary site to DR site.
	SRDF is (normally) a continuous process.
	The Primary site has the R1 source HVE and the DR site has the R2
	target HVE.

	The DR site can mount the R2 copy for use ONLY AFTER the SRDF has been 
	stopped (when replication is stopped).  The R2 can then be mounted on the 
	system.  ANY CHANGES to the R2 would either be lost or need to be reversed 
	sync'd BEFORE starting the normal primary to DR replication again.

	Another way to see the data at the DR site without effecting the SRDF
	volumes (R1 & R2), is to use BCVs.  A BCV would be split off the R2
	HVE and then mounted for testing.  The cost for this is disk space for
	the BCV.
