Quick fix: Nutanix. Restore admin password

It’s not a common situation, but it does happen sometimes, especially in test clusters.

To change the admin password we need to connect to the CVM, for example, using the nutanix user, and reset the password:

$ ncli user reset-password user-name=admin password=MyStrong@Passw0rd
Password of user 'admin' reset successfully
Please login again with new credentials.

The password should be strong and between 8 and 255 characters. It should differ by at least 4 characters from previous password and it should not be from last 5 passwords.

Now you can connect to Prism and use the password you just set.

Veeam Backup & Replication Instant Recovery to Nutanix AHV

I have previously written about how to connect VBR to a Nutanix cluster, as well as how to create backup tasks and restore.

In this article, we will talk about a very important VBR functionality – Instant Recovery, support for which was added with the release of Nutanix AOS 6.0 STS and AOS 6.5 LTS.

What’s new at Nutanix University?

Good news for Nutanix Cloud Clusters (NC2) users – two new courses and certification tracks have been announced.

Two free online courses:
Nutanix Cloud Clusters on AWS Administration (NC2A-AWS) – Configuring and administrating NC2 in the AWS environment;
Nutanix Cloud Clusters on Azure Administration (NC2A-Azure) – Configuring and administrating NC2 in the Microsoft Azure environment.

Both courses include a theoretical part and Hands-on Labs as well.

And there are new certifications – Nutanix Certified Professional – Cloud Integration for AWS and Azure.

NCP-CI-AWS 6.7;
NCP-CI-Azure 6.7.

As usual, both exams are in beta state, and you can take them for free. Use discount code NCPCIAWS67BETA for NCP-CI-AWS 6.7 exam and NCPCIAZURE67BETA for NCP-CI-Azure 6.7. This offer is only available to the first 250 participants, and the last day to test is March 10, 2024.

Using SSH key-based authentication and Lockdown mode in Nutanix clusters

Last year, a new check added to the NCC module may require your attention:

“Password-based remote login is enabled on the cluster. It is recommended to use key-based SSH access instead of password-based SSH access for better security.”

Although this check has a severity level of “Info”, if you dig a little bit deeper, you can find, that password-based authentication will be a deprecated authentication method since 2024. And we can only guess when key-based authentication will be not a recommendation, but a requirement.

In this article, we will look at Cluster Lockdown Mode and how to enable key-based access to the cluster.

How to backup Nutanix AHV using Veeam Backup and Replication 12.1 and Veeam Plug-In for Nutanix AHV v5

In this article, we will look at backing up Nutanix AHV virtual machines using VBR 12.1 and Nutanix AHV Plug-In v5.

The main difference between the v4 plugin and v5 is the possibility of creating backup jobs related to Nutanix AHV VMs right in the VBR console. You don’t need to connect to the backup appliance deployed in a Nutanix cluster to create a backup job.

Also, please make sure, that you’re using version 5.1 of the plugin or higher because of the critical bug found in v5.0.

What’s new at Nutanix University?

Nutanix has updated the Nutanix End User Computing Administration (NEUCA) course, which focuses on managing virtual desktop infrastructure, to version 6.5.

Following the course, according to tradition, the Nutanix Certified Professional – End User Computing (NCP-EUC) v6.5 exam has been updated.

The exam is currently available to take free of charge. You must register by December 28, 2023. When registering for the exam, you must use the code NXFREUC65.

Deploying Nutanix Community Edition 2.0 on VMware vSphere 8

This year Nutanix Community Edition 2.0 (CE 2.0) was released, based on Nutanix AOS 6.5 – the most actual LTS version at the time of writing.

In this article, we’ll take a closer look at how to deploy a three-node Nutanix CE 2.0 cluster on a VMware vSphere 8 infrastructure.

Preparing for the Nutanix Certified Master – Multicloud Infrastructure 6.5 Exam

Nutanix Certified Master – Multicloud Infrastructure 6.5 is the next certification level after NCP-MCI 6.5, and successful completion of this certification provides access to the NCX and NPX expert-level exams.

If we draw a parallel with the certifications of other vendors, this certification belongs to the Advanced Professional category and, for quite a long time, was called Nutanix Certified Advanced Professional (NCAP).

Since version 6.5, this exam has changed its format, and now it is not a familiar test, but a laboratory work with a certain number of scenarios and tasks that need to be performed on real clusters. Again, the closest analogies are VMware Certified Advanced Professional – Deploy or any of the Red Hat exams.

Next, we will look in more detail at what the exam is, the list of topics, as well as the preparation procedure.

Preparing for the Nutanix Certified Professional – Multicloud Infrastructure 6.5 Exam

Nutanix Certified Professional is the second stage in the Nutanix certification track. This certification requires the candidate to have good theoretical and practical knowledge of working with Nutanix solutions and is divided into several tracks:
Nutanix Certified Professional – Multicloud Infrastructure (NCP-MCI) v6.5
Nutanix Certified Professional – Database Automation (NCP-DB) v6.5
Nutanix Certified Professional – Unified Storage (NCP-US) v6.5
Nutanix Certified Professional – Multicloud Automation (NCP-MCA) v6.5
Nutanix Certified Professional – End User Computing (NCP-EUC) v6

Update: I have a new guide based on version 6.10.

In this article we will look at the main topics from the Nutanix Certified Professional – Multicloud Infrastructure (NCP-MCI) exam version 6.5, and I will also share materials, that you can use to prepare yourself.

Preparing for the Nutanix Certified Associate 6.5 Exam

Nutanix Certified Associate is the first step in the Nutanix certification track. This is an entry-level exam that tests knowledge of general Nutanix theory, basic cluster management skills, and an understanding of the Prism interface.

In this article I will share my experience of passing the Nutanix Certified Associate exam version 6.5, and also leave some tips for self-preparation.

Update: I have a new guide based on version 6.10.
