单项选择题During normal cluster processing in a five-node cluster，one of the nodes unexpectedly crashes. A review of the system dump indicates that a DMS timeout has occurred. The cluster is configured to use disk heartbeats as a Point-to-Point network. What should be done to address the problem with this configuration？（）

A. More disk should be added to the disk heartbeat network，allowing more paths for heartbeats.
B. An RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.
C. The network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.
D. An error notification method is required to determine the action to take in response to a failure of the disk heartbeat.
