Adding a node in a Nutanix cluster

Add a node and confirm that it is working properly

Last updated 5th April 2022


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.

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 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
  • You must be connected to the cluster via Prism Central
