    单选题
    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.
