When you are adding new features to your Nutanix environment, there might be a need to update the license or purchase a new one. If you do not update the license, there will be a red banner at the top of the Prism Page indicating that there are licensing violations.
Clicking on “View Licensing Details” will show offenders of the current license. Using NCLI, you can see more details about features available in the current license level and features that are not allowed.
For more information about disabling features, attaining the correct license, or temporarily removing the banner, look at KB 3443.
