Check the random port range of the system.

In the single-node system, the Controller resource is in the normal state. In the dual-node system, the Controller resource is in the normal state on the active node and in the stopped state on the standby node.

    • If it is not, go to 4.

  4. Run the vi $BIGDATA_LOG_HOME/omm/oms/ha/scriptlog/controller.log command to view the Controller resource logs, and run the vi $BIGDATA_LOG_HOME/controller/controller.log command to view the Controller running logs. Analyze the logs to locate and rectify the fault.
  5. Five minutes later, check whether this alarm is cleared.
