Impact on the System

  • The active/standby FusionInsight Manager switchover occurs.
  • The AOS process repeatedly restarts, which may cause the FusionInsight Manager login failure.

Procedure

Check the random port range of the system.

  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.
  2. Log in to the host for which the alarm is generated as user root.
  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 AOS resources managed by the HA is normal. In the single-node system, the AOS resource is in the normal state. In the dual-node system, the AOS 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/ha/scriptlog/aos.log command to view the AOS 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.

    • If it is, no further action is required.
    • If it is not, go to 6.

Collect fault information.

  1. On FusionInsight Manager, choose O&M > Log > Download.
  2. Select Controller and OmmServer for Service and click OK.
  3. Click in the upper right corner, and set Start Date and End Date for log collection to 1 hour before and after the alarm generation time, respectively. Then, click Download.
  4. Contact the O&M personnel and send the collected log information.
