In this case there is CD mapped
[root@ocp-edge111# ~]$ curl -u root:calvin -k https://10.46.98.49:443/redfish/v1/Managers/iDRAC.Embedded.1/VirtualMedia/CD/Actions/VirtualMedia.EjectMedia  -d  '{}' -X POST -H 'Content-Type: application/json' | jq

Immediately after I disconnect the CD with the first command I ran this command again and got error
