After the IVS Platform Is Upgraded, the Configured NTP Clock Source Is Disappeared from the OMU Portal

Symptom

When you log in to the OMU portal after the IVS platform is upgraded, the configured NTP clock source is disappeared from the OMU portal.

Possible Cause

You manually configure an NTP clock source in the /etc/ntp.conf configuration file.

 NOTE:

In the /etc/ntp.conf configuration file, the statements server 127.127.1.0# local clock (LCL) fudge and 127.127.1.0 stratum 10# LCL is unsynchronized specify that the server with the IP address 127.127.1.0 is configured as the NTP clock source. Then, the server with the IP address 127.127.1.0 is regarded as the local NTP clock source by default, so the NTP clock source is not displayed on the OMU portal.

Solution

You can rectify the fault in either of the following ways:

• Add comment tags (#) before the two statements in the /etc/ntp.conf configuration file.
  1. Log in to the server as the admin user and run the su - root command to switch to the root user.
  2. Run the vi /etc/ntp.conf command.
  3. Press I to make the file editable.
  4. Add comment tags (#) before the following two statements:
     • server 192.168.11.12# local clock (LCL) fudge
     • 192.168.11.12 stratum 10# LCL is unsynchronized
  5. After the modification, press Esc to exit the editing mode.
  6. Run the :wq command to check whether the fault is rectified.

     If the fault is rectified, no further action is required. If the fault persists, contact Huawei technical support engineers.

• Log in to the OMU portal and re-configure the NTP clock source.
  1. Log in to the OMU portal of the server.
  2. Choose Local Configuration > Server configuration, as shown in Figure 1.
     Figure 1 Server configuration
     
  3. Set Time-synchronize with the NTP clock source server to Yes.
  4. Set NTP server IP to the IP address of the NTP clock source server.
  5. Click Save and check whether the fault is rectified.
