How to Change the vRack of a Nutanix Cluster

View as Markdown

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

  • A Nutanix cluster in your OVHcloud account
  • An additional vRack service activated in your account
  • Access to the OVHcloud Control Panel

Instructions

Step 1: Removing services

Log in to the OVHcloud Control Panel.

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

Change vRack Nutanix cluster - step 1

Warning

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

Warning

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

 

Step 2: Adding services

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

Warning

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

Warning

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

 

Troubleshooting

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
