While adding the forced varyon volume group option， it is decided to create a disk heartbeat  Network over the disk paths. Which HACMP function is used to create disk heartbeat devices？（）

• A、 The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
• B、 HACMP does not create the disk heartbeat area directly； RSCT facility creates the area used for the disk heartbeat when the device is started by Group Services.
• C、 The ’Chdev -v-C " command creates an enhanced Volume Group from an ordinarilyVolume Group. This creates the heartbeat region on the vfirst disk in the chain.
• D、 The disk heartbeat area on the disk is created and initialized when the device is created inHACMP "Extended Configuration -> Extended Topology -> Disk heartbeat facility" smit path.
