Question
A customer implemented a PowerHA System Mirror cluster for their database. The cluster is used simultaneously by many clients during work hours. For the non-IP heartbeat network, they decided to use the same LUN as for the data files. Which problem can arise during normal use of the cluster?

- BThe cluster will not start, because it needs a separate LUN for non-IP heartbeat.
- CAreservation conflict can arise between the heartbeat function and normal data access.
- DA lock from one node in the cluster can prevent other nodes reporting heartbeat functions.
