The list of required IP addresses varies depending on the number of servers ordered (the solution offered by OVHcloud ranges from 3 to 32 nodes) and the configuration mode of **Prism Central** (**Alone** or **Scale**). Here are the details: - Between 6 and 36 IP addresses for physical servers (requires two addresses per server, one for the **AHV** hypervisor and another for the **CVM** virtual machine). - An IP address for **Prism Element**. - An IP address for the IP address of **Prism Central**. - three optional IP addresses for **Prism Central** scale-mode deployment with three virtual machines. - An IP address for the Internet gateway. **Warning:** **NOTE:** Some IP plan addresses are reserved for the **Load Balancer**. They are still on the network `XX.XX.XX.128/27`, i.e. the addresses between `XX.XX.XX.129,` and `XX.XX.XX.158` of the network. They should not be used during redeployment. Here are two possible examples of Nutanix cluster configuration at OVHcloud: **Example 1:** Reconfiguring a cluster with 3 nodes on an IP plan in `192.168.10.0/24`. - Server 1: VM address **CVM** `192.168.10.1`, hypervisor IP address **AHV** `192.168.10.21`. - Server 2: VM address **CVM** `192.168.10.2`, hypervisor IP address **AHV** `192.168.10.22`. - Server 3: VM address **CVM** `192.168.10.3`, hypervisor IP address **AHV** `192.168.10.23`. - **Prism Element** virtual address: `192.168.10.111`. - **Prism Central** IP address: `192.168.10.222`. - Scope reserved for the load balancer: `192.168.10.128 to 192.168.10.159`. - Gateway: `192.168.10.254`. **Example 2:** Reconfiguring a cluster with four nodes in Scale mode for **Prism Central** on an IP plan in `172.16.0.0/16`. - Server 1: VM **CVM** `address 172.16.0.1`, hypervisor IP address **AHV** `172.16.0.21`. - Server 2: VM address **CVM** `172.16.0.2`, hypervisor IP address **AHV** `172.16.0.22`. - Server 3: VM **CVM** `address 172.16.0.3`, hypervisor IP address **AHV** `172.16.0.23`. - Server 4: VM **CVM** `address 172.16.0.4`, hypervisor IP address **AHV** `172.16.0.24`. - **Prism Element** virtual address: `172.16.0.111`. - **Prism Central** IP address: `172.16.0.222`. - VM Prism Central: `172.16.0.223 to 172.16.0.225`. - The load balancer: `172.16.0.128 to 172.16.0.159`. - Gateway: `172.16.0.254`. ## Instructions We will redeploy a cluster with three nodes, as in Example 1 (above), either from the OVHcloud Control Panel or from the OVHcloud API. **Warning:** **NOTE:** The Cluster redeployment operation cannot be undone. All data in the Cluster will be deleted, and a new admin account password will be generated and sent by email to the OVHcloud customer account holder. ### Redeploy the cluster from the OVHcloud Control Panel In the OVHcloud Control Panel, click on the `Hosted Private Cloud` tab, select your cluster below the `Nutanix` category on the left-hand side, then click on `Redeploy cluster`.   When the pop-up appears, click `Next`.   Click `Customize the Configuration` and click `Next`. Enter the information for each of your nodes, which are: - the private IP address of your AHV hypervisor. - the private IP address of the CVM virtual machine. Then scroll through the window. Leave these default settings : - **Replication Factor:** RF2. - **Erasure Coding feature:** Erasure Coding disabled. - **Prism Type:** Alone. Modify these values: - **Prism Central VIP:** Prism Central private IP address. - **Prism Element Virtual IP(VIP):** Prism Element private IP address. - **CIDR Gateway:** Private IP address of the gateway followed by the subnet mask, in the following form XX.XX.XX.XX/XX. - **AOS Version:** Version of AOS chosen during redeployment. Then click `Redeploy`.   Enter `REDEPLOY` and click `Confirm`.   **Warning:** **NOTE:** The Cluster redeployment takes a minimum of two hours. Wait until the OVHcloud account holder receives an email **before** using the Cluster again. The **Load Balancer** is reconfigured during redeployment and points the FQDN address of the Cluster to the private address of **Prism Central**.   ### ### Redeploy the cluster through the OVHcloud API Log in to the [OVHcloud API](https://api.us.ovhcloud.com/). For more details on how the OVHcloud API works, please refer to our guide, [First Steps with the OVHcloud API](https://docs.us.ovhcloud.com/en/manage-and-operate/api/first-steps.md). Use the following API call: [PUT /nutanix/{serviceName}](https://api.us.ovhcloud.com/console/?section=/nutanix&branch=v1#put-/nutanix/-serviceName-) Enter this data: - **ServiceName:** `FQDN name of your Nutanix Cluster`. - **redeploycluster:** `Check the box`. - **gatewayCidr:** `The gateway IP address followed by the subnet mask`. Enter the following information below **nodes:** - **ahvip:** `IP address of the hypervisor of the first node`. - **clip:** `IP address of the first node's CVM`. Then click the `+` button. Add the information for the second node: - **ahvip:** `IP address of the hypervisor of the second node`. - **cvmip:** `IP address of the second node's CVM`. Click the `+` button again. Then add the information for the last node: - **ahvip:** `IP address of the hypervisor of the last node`. - **cvmip:** `IP address of the last node's CVM`. Then scroll through the browser window with the scroll bar. In the **Prism Central Configuration** section: - Check `Define property` and `Empty array`. - Choose `alone` from the **type** drop-down menu. - Enter `the IP address of Prism Central` in the **vip** drop-down menu. Then enter: - `The IP address of Prism Element` in the **prismElementVip** drop-down menu. - The `number of the redundancy factor` in the **redundancyFactor** drop-down menu. - The `version number of the cluster` in the **version** dropdown menu. Click `Execute` to start the cluster redeployment. **Warning:** **NOTE:** The Cluster redeployment takes a minimum of two hours. Wait until the OVHcloud account holder receives an email **before** using the Cluster again. The **Load Balancer** is reconfigured during redeployment and points the FQDN address of the Cluster to the private address of **Prism Central**.   ## Go further Browse all the [Nutanix guides](https://docs.us.ovhcloud.com/en/hosted-private-cloud/nutanix-on-ovhcloud/landing-page-nutanix-on-ovhcloud.md).
