Nutanix clusters are scalable. You can add nodes to an existing cluster.
This guide will show you how to add a node and ensure it works properly.
Warning
OVHcloud provides services for which you are responsible, with regard to their configuration and management. You are therefore responsible for ensuring they function correctly.
This guide is designed to assist you in common tasks as much as possible. Nevertheless, we recommend that you contact the OVHcloud Professional Services team or a specialist service provider if you have difficulties or doubts concerning the administration, usage or implementation of services on a server.
- A Nutanix cluster in your OVHcloud account
- Access to the OVHcloud Control Panel
- Access to the OVHcloud API.
- You must be connected to the cluster via Prism Central
- A ready-to-configure physical server added to the OVHcloud Control Panel
The Hosted Private Cloud solution powered by Nutanix enables you to have between 3 and 18 nodes on the same cluster.
It is possible to add several nodes when expanding the cluster.
The nodes to be added must have the same version of AOS as the existing cluster.
Log in to your OVHcloud Control Panel and check that an additional node appears in the Nutanix cluster.

You can also check this via the OVHcloud API.
Use the following API call:
[!api]
@api {v1} /nutanix GET /nutanix/{serviceName}
serviceName: enter the cluster name
{.thumbnail}
The new node appears with 0.0.0.0 IPs.
To install the new node, you must change the cluster properties by making a PUT on the cluster.
To do this, use the following API call:
[!api]
@api {v1} /nutanix PUT /nutanix/{serviceName}
Warning
Make sure to untick the redeployCluster box.
Tick the scaleUp box.
Enter the following information below nodes:
- ahvip : IP address of the hypervisor of the new node.
- cvmip : IP address of the CVM of the new node.
Warning
These IP addresses must not already be used and must match your addressing plan.
You must also complete the deployment version. It may not correspond to the current version of your cluster. This is not an issue as the node will be modified by the Nutanix installer when adding it to the cluster via Prism Element.

Click Execute{.action} to send the request.
In the "Result" tab, the new node appears with the new IP address.
At the end of the installation, you will receive an email confirming that the node is ready.
Dear Customer,
