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 obtain Network Time Protocol (NTP) server information:

    ntpq -p

    In the command output, the remote column displays the NTP server IP address.

  7. 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 6 is used to establish the connection.

    The default username is untp, and the default password is Huawei12#$.

  8. Run the following command to check the connectivity between the local node and the NTP node of the upper-level clock source:

    ntpdate -q Clock source IP address

    • If information similar to the following is displayed, the local node and the NTP node of the upper-level clock source are connected.
      [root@TDNS-TNTP02 fsp]# ntpdate -q 172.16.0.0
      server 172.16.0.0, stratum 11, offset -0.000138, delay 0.02583
      25 Jan 10:34:02 ntpdate[4956]: adjust time server 172.16.0.0 offset -0.000138 sec
    • Otherwise, they are not connected. Check the network configuration and firewall and try again.

  9. 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.

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

    service ntpd restart

  11. Run the following command to synchronize system time of the node:

    ntpdate NTP server IP address

  12. Run the following command to write the new system time to the hardware clock:

    hwclock -w

  13. Run the following command to restart the faulty node:

    reboot

  14. After 3 minutes, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 15.
