Today while working on one of the production issue, I came across situation where I deployed a new vDC from vCloud Air portal, but after the vDC was created successfully, I was not able to list the edge gateways/org networks for this vDC.
On checking vCloud Director, I found that edge gateway creation failed and was showing below errors:
[ 7267fcbe-194f-47c6-bee1-029a2e445e48 ] Deployment of edge gateway gateway failed.
- com.vmware.vcloud.fabric.nsm.error.VsmException: VSM response error (1256006): Operation is not allowed by the applied NSX license.
- VSM response error (1256006): Operation is not allowed by the applied NSX license.
I logged in Web Client and navigated to Administration > Licenses view and was bot able to see any licenses there. This was a bit strange. I understood right at that moment that there is some issue with licensing service.
