Managing the KeyControl License

Your KeyControl license determines the number of KeyControl nodes you can have in a cluster, the number of VMs that you can manage, and the length of time for which you can use KeyControl.

If your license expires, you can still access or decrypt your VMs using the keys managed by KeyControl. You can also continue to manage KeyControl or your VMs using the KeyControl webGUI or hicli. However, you cannot:

• Register a new VM with KeyControl.
• Encrypt any new data, root, or swap disks, even if they have already been registered with KeyControl.

If your license is about to expire, or if you have registered the maximum number of VMs allowed by your license, KeyControl sends the following alerts:

• If your license will expire in 7 to 60 days, KeyControl sends an alert once per week.
• If your license will expire in less than 7 days, or if your license has already expired, KeyControl sends an alert once per day.
• If you have registered the maximum number of VMs allowed by your license, KeyControl sends an alert once per week.

Procedure 

1. Log into the KeyControl webGUI on any node in the cluster using an account with Security Admin privileges.
2. In the top menu bar, click Settings.

3. In the System Settings section, click License and look at the Expiration & Restrictions section.

   Available Fields

   Field	Description
   Expires On	The date on which this KeyControl license expires. If the license expires, you can still access the data on any encrypted VMs using keys managed through KeyControl, but you cannot make any modifications to the system through the KeyControl webGUI. Any user who logs into the webGUI is redirected to a page stating that the KeyControl license needs to be updated.
   KeyControl Limit	The maximum number of KeyControl nodes that you are allowed to have in a cluster.
   Cloud VM Limit	The maximum number of VMs that you are allowed to manage with KeyControl.

4. If you need to request a new or upgrade license, follow the instructions at the bottom of the License page. Your request should include the License ID and the License Version displayed in this section.

   Tip:

   If you want to remove a currently registered VM from KeyControl so that it no longer counts against the "Cloud VM Limit" in your license, see Removing a VM from KeyControl or Decommissioning and Destroying a VM.

5. If you want to upload a new license file:

   1. Click Browse and select the new license file.
   2. Click Upload File.
   3. Accept the EULA (End-User License Agreement) when prompted.
   4. Verify that the correct information now appears in the Expiration & Restrictions section.
