You are therefore responsible for their proper functioning.\ \ This tutorial is designed to help you as much as possible with common tasks. If you are having difficulty performing these actions, please contact a specialized service provider. OVHcloud cannot provide you with technical support in this regard.   ## Requirements - Access to the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/) or [OVHcloud API](https://api.us.ovhcloud.com/) - A Nutanix cluster in your OVHcloud account - Access to the cluster's Prism Central administration interface   ## Technical information - Your cluster must have between **3 and 32 nodes** - All new nodes must run the **same AOS version** as the existing cluster   ## Instructions ### Scale Out (add a node) #### Add a node From the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/), navigate to your Nutanix cluster via the `Hosted Private Cloud` and `Nutanix` menus. In the **General information** tab, you can see the **Number of nodes**. Click `Manage my nodes →`. In the **Nodes** tab, select `Add nodes`. In the pop-up window, review the configuration information and pricing. Click `Order` to add the node(s). Once the node is delivered, you can see the status in the **General information** tab. The **Number of nodes** area will show a new node to install.   #### Install an OS ##### OVHcloud Control Panel If you click `Manage my nodes →` again, you will see a list of your nodes. For any node with a `OS not installed` status, click the _more options_ `...` button and select `Install`. Enter the configuration details for your node. Be sure to install the same AOS version as your cluster. Click `Install`. A confirmation message will appear. ##### OVHcloud API To install your node via the [OVHcloud API](https://api.us.ovhcloud.com/), use this call: [PUT /nutanix/{serviceName}/nodes/{server}/deploy](https://api.us.ovhcloud.com/console/?section=/nutanix&branch=v1#put-/nutanix/-serviceName-/nodes/-server-/deploy) Once the node has been installed, you can connect to Prism Central/Element and expand your cluster. Please refer to the documentation below: - [Expanding a Cluster through Prism Central](https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2024_3_1:mul-node-add-pc-t.html) - [Expanding a Cluster](https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v7_0:wc-cluster-expand-wc-t.html)   ### Scale In (remove a node) #### Power down a node From the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/), navigate to your Nutanix cluster via the `Hosted Private Cloud` and `Nutanix` menus. In the **General information** tab, you can see the **Number of nodes**. Click `Manage my nodes →`. ##### OVHcloud Control Panel For the node you wish to remove, click the _more options_ `...` button and select `Power down`. A warning pop-up will appear. Type the required term and click `Power down`. **Warning:** **NOTE:** Powering down a Nutanix node may impact your cluster. Please check the [requirements on the Nutanix portal](https://portal.nutanix.com/page/documents/list?type=software) to complete this action. A confirmation banner will appear to confirm that your request is processing. ##### OVHcloud API You can also power down your node via the [OVHcloud API](https://api.us.ovhcloud.com/). Get the Boot ID: Enter _power_ as the **bootType**. [GET /dedicated/server/{serviceName}/boot](https://api.us.ovhcloud.com/console/?section=/dedicated/server&branch=v1#get-/dedicated/server/-serviceName-/boot) Set the Boot ID: [PUT /dedicated/server/{serviceName}](https://api.us.ovhcloud.com/console/?section=/dedicated/server&branch=v1#put-/dedicated/server/-serviceName-) Power down the node: [POST /dedicated/server/{serviceName}/reboot](https://api.us.ovhcloud.com/console/?section=/dedicated/server&branch=v1#post-/dedicated/server/-serviceName-/reboot)   #### Uninstall the node ##### OVHcloud Control Panel Once the node is powered down, click the _more options_ `...` button and select `Uninstall`. A warning pop-up will appear. Type the required term and click `Uninstall`. **Warning:** **NOTE:** Uninstalling a Nutanix node may impact your cluster. Please check the [requirements on the Nutanix portal](https://portal.nutanix.com/page/documents/list?type=software) to complete this action. A confirmation banner will appear to confirm that your request is processing. ##### OVHcloud API To uninstall your node via the [OVHcloud API](https://api.us.ovhcloud.com/), use the following call: [POST /nutanix/{serviceName}/node/{server}/terminate](https://api.us.ovhcloud.com/console/?section=/nutanix&branch=v1#post-/nutanix/-serviceName-/node/-server-/terminate)   #### Remove the node Once the node is uninstalled, click the _more options_ `...` button and select `Terminate`. A warning pop-up will appear. Type the required term and click `Confirm`. **Warning:** **NOTE:** Your suspended service will appear in your nodes list for approximately one week before being permanently deleted.
