Nasty little issue here. When you try to mount an ISO to the KVM of a Quanta node you are greeted with this fine message. CD Port: 5120 is only Listening. Closing the CD redirection
Followed by: CD/DVD image redirection failed to start
In order to get your ISO mounted you will need to restarting the cd-media service. Firstly got back to the BMC Main menu. Select the Remote Control Menu then the “Services” sub menu.
You will need to edit the Nonsecure Port number to a non conflicting port number .
I set Port 5128 in this screen shot. Once Complete. Click on the “Modify” button to change the setting.
Once you edit the config and save the changes you get confirmation that the service will be restarted once you click OK.
I would suggest changing the Port number back to the original 5120. You can then mount your ISO. Note you will need to close any KVM session you have open on the BMC.
