How to Change the vRack of a Nutanix Cluster – Support Guides

A Nutanix cluster is delivered with its own vRack. To interconnect with other OVHcloud services, you can attach your cluster to a different vRack.

This guide explains how to add a Nutanix cluster to another vRack.

Requirements

Open the Nutanix cluster vRack configuration page, select all the services (e.g. dedicated server, IP, load balancer), and click on Remove.

NOTE: Before removing services, make sure to save their references, especially if you have many servers, IPs, load balancers, etc.

NOTE: Removing services from the vRack is not immediately effective. Please allow some time for the process to complete.

Once the process is finished, go to the desired vRack and add all the previously removed services with the Add button.

NOTE: Adding services to the vRack is not immediately effective. Please allow some time for the process to complete.

NOTE: Accessing Prism Central is not instantaneous; the VM must restart to make the access effective again.

If Prism Central stays inaccessible after 30 minutes, create a front-end on the load balancer to reach a CVM with SSH.

When logged in, check if the Prism Central VM is on.

acli vm.get prism-central |grep state

If the answer is state: "kOff" then start the VM:

acli vm.on prism-central

You can also restart the VM with the following command:

acli vm.guest_reboot

Alternatively, do a hard reboot (if the previous attempts failed):

acli vm.reset
