Learn how to add a node and ensure it works properly.
Nutanix clusters are scalable. You can add nodes to an existing cluster.
- 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.
Checking node delivery
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:
serviceName: enter the cluster name
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:
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.
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.
Execute 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.
Your server has just been installed.
You must now add it back to your Nutanix cluster by connecting to Prism Central: https://cluster-xxxx.nutanix.ovh.net:9440
