Impact on the System

The service on the node where the alarm is generated is unavailable.

Possible Causes

  • The ETCD process cannot be started because the NTP server of the node is abnormal.
  • The ETCD process cannot be started because the ETCD configuration is incorrect.
  • ETCD is in unhealthy status because the node cannot communicate with other CPAS nodes.
  • The node is powered off abnormally and the ETCD database is damaged. As a result, the service process cannot be started.

Handling Procedure

  1. Log in to ManageOne Maintenance Portal using a browser.

    • URL: https://Address for accessing the homepage of ManageOne Maintenance Portal:31943, for example, https://oc.type.com:31943
    • Default username: admin; default password: Huawei12#$

  3. In the alarm list, locate the alarm to be handled, and click on the left of the alarm. The Details page is displayed.
  4. Choose Location Info, obtain the host IP address, that is, the IP address of the node where the alarm is generated.
  5. Use PuTTY to log in to the node for which the alarm is generated. Ensure that the management IP address of the node obtained in 4 is used to establish the connection.

    The default username is arbiter. The default password is tNsZg@123.

  6. Run the following command to check whether the status of the process is active (running):

    systemctl status arbitration-etcd

    Perform further actions based on the command output.

    • If the command output contains "active (running)", go to 14.
    • If the command output does not contain "active (running)", go to 7.

  7. Run the following command to query the NTP service status.

    ntpq -p

    Perform further actions based on the command output.

    • If the command output contains "ntpq: read: Connection refused", the NTP service on this node is abnormal. In this case, go to 8.
    • In the command output, if the NTP service IP address is not started with * in the remote column, the NTP service is abnormal. In this case, go to 10.
    • In the command output, if the NTP service IP address is started with * in the remote column, the NTP service is normal. In this case, go to 11.
    • For other command output, go to 16.

  8. Run the following command to restart the NTP process:

    systemctl restart ntpd

  9. Wait for 5 minutes and run the following command to query the NTP service status:

    ntpq -p

    Perform further actions based on the command output.

    • In the command output, if the NTP service IP address is not started with * in the remote column, the NTP service is abnormal. In this case, go to 16.
    • In the command output, if the NTP service IP address is started with * in the remote column, the NTP service is normal. In this case, go to 11.
    • For other command output, go to 16.

  10. Contact the administrator to check whether the network between the node and the NTP server is normal and whether the NTP server is normal. After restoring the connection, go to 8.
  11. Run the following command to restart the ETCD process:

    systemctl restart arbitration-etcd

  12. Run the following command to check whether the status of the process is active (running):

    systemctl status arbitration-etcd

    Perform further actions based on the command output.

    • If the command output contains "active (running)", go to 13.
    • If the command output does not contain "active (running)", go to 16.

  13. Wait for 3 minutes and check whether the alarm is automatically cleared.

    • If yes, no further action is required.
    • If no, go to 14.

  14. Contact the administrator to check whether the network between the node and other CPAS nodes is normal. After restoring the connection, go to 15.
