Changing vCenter IP via DCUI fails

I prepared a demo environment for one of my customers, who requested IP changes at short notice, so I wanted to adjust them over the DCUI accordingly, but I got the following error message:

To change IP addresses, netmasks, gateways, and host names in general, there is another option that works on a CLI basis. To do this, open the vCenter Shell.

shell

Then we open the VAMI Configuration Utility with the following command:

/opt/vmware/share/vami/vami_config_net

Now we have the option to change various parameters. To do this, select the appropriate number and then press 0 again at the end so that you can view all the settings you have made. If everything is correct, exit the utility by pressing 1.

In my case, I had to change the IP address of the vCenter and therefore select option 6. Once you have answered all the following questions and entered the desired parameters, the following message appears:

Reconfiguring eth0...
Network parameters successfully changed to requested values

Finally, I selected 0 to exit the utility. That’s all for this blog post. If you have any questions, please use the comments section below.
