Hello, dear!
Today I want to share with you how to deal with the problem that MU is offline.
Problem description
No error is reported during the installation of the VCN3020 V100R003C10SPC110. After the installation is complete, log in to the OMU portal, choose Local Configuration > Server Configuration, change the IP address, and save the change. The system displays a message indicating that the MU is offline and the IP address cannot be changed.
Handing process
1. Log in to the OMU, choose System Management > Service Running Management, and check the module running status. The check result shows that the MU module does not exist.
2. Use SSH to log in to the server as root user and run the ps -ef | gref mu command to check whether the MU process exists. The check result shows that no MU process exists.
3. Run the following command to restart the MU module.
cd /home/ivstool/bin
./service.sh restart mu
4. After the restart is complete, run the ps -ef | grep mu command to check the MU process. The check result shows that no MU process exists.
5. Log in to the OMU, switch the NE mode to the VMU, and then to the MPU. The problem persists.
(You are advised to perform this operation when no service is running. )
6. Check whether files related to the MU process exist.
If no, reinstall the operating system.
If related files exist, upgrade the VCN.
Upgrade the VCN to V100R003C10SPC315. The problem is solved.
Summary
If the MU does not exist, run commands to manually restart the MU. If the restart fails, upgrade or reinstall the operating system (no services are running) to resolve the problem.
Thanks for reading!
