Procedure

Check whether the PMS process is abnormal.

  1. In the alarm list on FusionInsight Manager, locate the row that contains the alarm, and view the name of the host for which the alarm is generated.

  3. Run the su -omm command and then the sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh command to check whether the status of the PMS resources managed by the HA is normal. In the single-node system, the PMS resource is in the normal state. In the dual-node system, the PMS resource is in the normal state on the active node and in the stopped state on the standby node.

    • If it is, go to 6.
    • If it is not, go to 4.

  4. Run the vi $BIGDATA_LOG_HOME/omm/oms/pms/pms.log and vi $BIGDATA_LOG_HOME/omm/oms/pms/scriptlog/pms_ha.log commands to view the PMS resource logs, check whether the keyword ERROR exists. Analyze the logs to locate and rectify the fault.
  5. Five minutes later, check whether this alarm is cleared.
