If ESXi 6.5 is not available as one of the choices for hypervisor during the Foundation process, the consultant should upload the ESXi image to the specific directory where Foundation expects to find hypervisor images.
The correct path for this operation is /home/Nutanix/foundation/isos/hypervisor/esx. This allows the Foundation tool to detect and use the ESXi image for installation on the nodes.References: Nutanix Foundation Guide, Nutanix Support Documentation.

When installing a Nutanix cluster on hardware servers pre-loaded with an existing operating system such as DiscoverOS, the best approach is to re-image the bare metal nodes. This process involves using the Nutanix Foundation tool to install the required Nutanix software (such as AOS and Hypervisor) onto the nodes, replacing any pre-existing software. This ensures that the hardware is properly configured and optimized for the Nutanix environment.References:

When deploying a multi-node Nutanix cluster, if one node fails to image and the Nutanix Foundation tool cannot configure the cluster automatically, the consultant can manually create the cluster with the nodes that were successfully imaged. The correct command to initiate this process is cluster create. This command starts the cluster services and allows for further expansion once the cluster is operational, which would include adding the node that initially failed to image.
