We're running v6.5 with an Essentials Plus licence and have successfully registered the licence with the one ESXI instance we have. However, despite uploading the licence successfully to vCenter Server using the Powercli instructions here - https://www.altaro.com/vmware/vsphere-licensing-powercli/ - (we can't install the licence using vCenter Client as the functionality for that is not available in v6.5) we cannot add a host to our vCenter Server.
At the "Assign License" step in the "Add Host" process, "The license assignment is valid" message is displayed. However, "Usage" in the same window shows 2 CPUs (which is correct), but "Capacity" shows 0 CPUs.
In the next two steps, Lockdown mode is set to disabled and the VM Location is correct.
Unfortunately, after clicking Finish, the "License not available to perform the operation." error is displayed and the Add Host process fails.
In case it matters, there is also an expired evaluation license on the server (it shows up in the Add Host dialog) but the Essentials Plus license was selected for the above process, not this eval license.
Any possible solutions v gratefully received. Thx.
