After writing an update to the article on deploying the solution, here is the update on adding a source to your HYCU controller.

Prerequisites for adding a Nutanix AHV cluster

Among the first prerequisites, the Data Service IP must be configured on your Nutanix cluster:

To be able to add a Nutanix AHV cluster as a source on your HYCU controller, you will need an account capable of connecting to your cluster and to your Prism Central if you have one.

I recommend using a dedicated account and not using the admin account of your cluster whose password will change regularly.

Last point, obvious but always good to remember, the HYCU VM and your cluster / Prism Central must be able to communicate.

Once all the prerequisites have been met, you can proceed to adding the cluster to your controller.

Adding the Nutanix cluster to HYCU

On your HYCU interface, in the toothed wheel at the top right, click on source:

Add your Nutanix cluster (IP_ADDRESS:9440) with the service account that you have dedicated to HYCU then click on “Next”:

Repeat the operation if you have a Prism Central:

Your cluster is added to your controller:

You can find it in the “HYPERVISOR” tab of the “Sources” window:

And on the home page of your HYCU controller:

Your Nutanix cluster is ready to be backed up.
