Failure to Start Some Modules When the System Powers off and Restarts After the Server IP Address Is Changed

Symptom

After you log in to the OMU portal of the server, change the server IP address, and click Save, the system powers off. After the system is restarted, some modules cannot be started.

Possible Cause

During the system power-off, the IP addresses in some configuration files are not changed yet.

Solution

The following assumes that the server IP address before the change is 192.168.2.20. The server IP address needs to be changed to 192.168.2.30.

1. Run the ping 192.168.2.20 command.
   • If the server can be pinged, go the next step.
   • If the server cannot be pinged, contact Huawei technical support engineers.

2. Use the original server IP address to log in to the server as the admin user and run the su - root command to switch to the root user.
3. Run the /home/ivs_sudo/ivs_omu/bin/modify_all_config_local_ip.sh 192.168.2.20 command.
    NOTE:

   After the command is executed, do not perform the next operation immediately. You need to perform the next operation after 5 minutes.

4. Run the reboot command to restart the server.

   After the server is restarted, the power-off fault is rectified, and the server IP address is stored to the original server IP address.

5. Change the server IP address.
   1. Log in to the OMU portal of the VCN as the Admin user.
   2. Choose Local Configuration > Server Configuration.
   3. Change the server IP address based on the onsite plan. In this scenario, set the server IP address to 192.168.2.30.
   4. Click Save.

      After the server is configured, the VCN automatically restarts. After the VCN restarts, use the new IP address to access the OMU portal.
