Rubrik : How to add Nutanix Cluster

Background

Rubrik can connect to Nutanix clusters running AHV since August 2017. This is a perfect fit mixing simplicity and efficiency from both worlds. To have secured communications between the two platforms, there are some mandatory steps that needs to be done.


Let's add Nutanix AHV

First, we need to extract the SSL key from the Nutanix cluster. Before going further, you need the following information :
  • Cluster IP;
  • Cluster UUID;
  • Service account with admin credentials on the Nutanix Cluster;
  • Nutanix CA certificate
Furthermore, there are some requirements : 
  • Rubrik v 4.0.3 or greater;
  • Nutanix AOS 5.1.x with REST API v3
To extract the Nutanix CA Certificate, connect with ssh to any of the CVMs and issue the following commands :

nutanix@NTNX-15SM15100xxx-B-CVM:192.168.8.184:~$ python
>>>> import ssl
>>> print ssl.get_server_certificate (('192.168.8.189', 9440),ssl_version=ssl.PROTOCOL_TLSv1_2)

If you are running Nutanix AOS 5.5 : contact support before adding your cluster, there is something support has to do before being able to add it. This is related to nutanixAosVersionRegexCheck. In my case the value is "^(5\\.(5|1\\.[1-5])(\\..*)?|2017\\..*|2018\\.0[1-4]\\.[0-9]{2})$".
Note : Starting with Atlas v4.1, the parameter changed from nutanixAosVersionRegexCheck to nutanixOsVersionRegexCheck. However, the content remains the same.

From the Rubrik UI, in the gear menu, chose Manage Nutanix Clusters, then Add Nutanix Cluster.




To get the Nutanix Cluster UUID you can have a look at the Prism interface clicking on the cluster name (top left) or using the command ncli cluster info from one of the CVM.

Once your Nutanix Cluster has been added into Rubrik, you will be able to see the VMs and start protecting them by applying the relevant SLA.
