单项选择题A two-node cluster is attached via SAN to shared disk. The customer has requested that one of the nodes be moved to another room 300 feet away. However， this distance exceeds the length specified by the RS232 specifications. What solution would resolve the RS232 specification issue with the fewest additional components？（）

A. Target mode fiber channel can be used with a SAN solution.
B. The heartbeat could be established by using a disk heartbeat.
C. An RS232 line driver can be used to extend the existing serial connection.
D. The NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.

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.
