Utilizing the cvm_shutdown Script

When performing maintenance on a CVM, it is important to not treat it as a regular guest VM. This is because there are crucial services running on each CVM which need to gracefully respond when a CVM goes offline.If you need to shutdown a CVM and are running ESXi, you might otherwise think to simply go to vCenter, right-click on the CVM, and select the “Shut Down Guest OS” option. However, that procedure will not properly shut down the CVM and allow the services to gracefully respond.Instead, in using the cvm_shutdown script, it will first place a necessary HA route in the hypervisor, to redirect storage requests to another CVM, before shutting down the CVM. This will also allow the services to gracefully respond to the CVM being offline.More information and options regarding this script can be found in KB 3270

Installing Discrete Graphics Host Drivers on AHV Hosts

Did you know that AHV hosts can be accelerated by discrete graphics hardware (similar to how home gaming systems are accelerated)? This is especially useful for environments such as Virtual Desktop Infrastructure (VDI) deployments where it is desirable to accelerate individual desktops being shared out to large user communities.The host driver for the discrete graphics hardware can be easily installed on AHV hosts via a single command as executed from just a single CVM of a Nutanix cluster (executing the command from a single CVM will install it across all of the CVMs of the cluster – no need to touch each CVM/host individually). Information regarding this single-command procedure can be found from the INSTALLING NVIDIA GRID VIRTUAL GPU MANAGER (HOST DRIVER) section of the AHV ADMINISTRATION GUIDE.Also, just to note, the host driver can be installed on hosts running an ESX hypervisor using a different procedure. That procedure can be found via the knowledge base article Install NVIDIA

field installation

In the process of installing the nx-8235-g7 equipment, the foundation cannot perform IPMI MAC ADDRESS DISCOVERY.When the installation was powered on, it was booted into Phoenix.iso and the IPMI IP setting was possible, so the installation was possible with the foundation. Is there any change in IPMI MAC DISCOVERY method from G7 equipment? And when the equipment is received and powered on, it boots into Phoenix.iso. Can you know what this is?And starting from g7, is the IPMI DEFAULT PASSWORD indicated by a sticker on the back of the device where the ipmi ID/PASSWORD is not ADMIN/ADMIN?

Combining a mixed hypervisor cluster with mixed hardware

We have a 4 node cluster configured as follows:2 x Lenovo HX1320 (dual 8-core Xeon Silver 4110 CPU @ 2.10 Ghz / 192 GB RAM / 7.11 TB storage) with ESXi2 x Lenovo HX5520-C (single -core Xeon Silver 4110 CPU @ 2.10 Ghz / 64 GB RAM / 35.83 TB) with AHVWe would like to convert the ESXi nodes to AHV. Looking at the knowledge base and the community it seems like doing this would allow all 4 nodes to share the virtual machine load and because the CPUs are the same we should not have to worry about compatibility issues. Is this a correct assumption? Any issues we should watch for?

Appendix: Imaging A Node (Phoenix)

Phoenix is an ISO-based installer that you can use to perform the following installation tasks on bare-metal hardware one node at a time: Configuring hypervisor settings, virtual switches, and so on after you install a hypervisor on a replacement host boot disk. This option does not require you to include AOS and hypervisor installers in the Phoenix ISO image. Installing the Controller VM, which runs AOS. This option requires you to include the AOS installer in the Phoenix ISO image. Installing the hypervisor on a new or replacement node. This is an alternative to installing the hypervisor by the use of the hypervisor manufacturer's ISO and reduces the two-step procedure—that of first installing the hypervisor and then installing AOS (by the use of the Phoenix ISO image)—to a single-step procedure of installing both software, at once, by the use of only the Phoenix ISO image. However, this option requires you to include the hypervisor ISO image and the AOS installer files in the Ph

How to configure a web server for LCM Dark Site on a Linux machine

If your cluster has no direct access to the internet, you can use the Dark Site LCM bundle, which you can put on a local web server and use it as a source for the LCM downloads.The web server can be a machine on the same Nutanix cluster that you want to upgrade or any other machine that the cluster will have access to. In this topic we will be creating a web server on a Linux machine and we will be using Apache Web Server. Note that this guide is for absolute beginners, so you will not need any prior experience. For this example, I have selected CentOS 7 as Linux distribution. If you want to use another distribution, the commands can be slightly different, so you will have to consult the documentation of the selected distribution. However, if you use CentOS, you can simply follow this guide. So, to start, install the CentOS selecting the “minimal install” and log in as root. Also, you can select in the installer in the Software Selection the Basic Web Server option. Then, you can skip

In this topic we will be creating a web server on a Windows machine and we will be using Microsoft IIS (Internet Information Services), so you will not need to download and install any third party software. Note that this guide is for absolute beginners, so you will not need any prior experience with this technology. So, first, we need to enable the IIS. Type the “Server Manager” in the Windows search and launch it.In the Server Manager click Manage in the top right corner and select “Add Roles and Features”.

How do you remove an Objects store?

So, on a dev cluster with Prism Central I created a Proof-of-Concept Nutanix Objects "Store". I did some experimentation (spotted a few problems with the deployment) and then decided I wanted to remove the store. First off I tried to delete the bucket, and was told "You need to delete all versions first": grr! Went and deleted all objects, but this wasn't enough, as versioning was enabled. So, turned version lifespan down to 1 day, and waited 24 hours. Great, now I could delete the bucket - however, I can't find any option to delete the store. So, I'm stuck with the (in my mind, greedy) VMs the deployment created, as I can't even go behind it's back and do anything with the VMs, as they're "special", just like the hidden Calm project which is used to deploy the store. All in all, not very impressed on first experiences...

Nutanix Installation with different network ports speed

Hello Everybody,Hope you’re all doing well !I want to install Nutanix using Foundation.I have 3 Lenovo nodes and one Cisco 2960X switch that consists of 24 x 1 Gig RJ45 ports and 04 x 1 Gig SFP ports.Unlike Supermicro nodes, Lenovo nodes do not have Shared IPMI ports.So, for each Lenovo node, I have to connect 01 x 10 Gig port and 01 GbE IPMI Port to the same CISCO 2960X switch (10 Gig ports of the nodes connected to 1 Gig SFP ports of the switch and 1Gig IPMI ports to the 1 Gig RJ45 ports ).Please take a look of the picture below…Since 10 Gig ports of the nodes are connected to 1Gig ports of the switch, I wonder if this architecture can allow me to install nutanix and create the cluster without any issues ?

Upgrade AHV on AWS Cloud instance

HI We use an AWS cloud instance as a remote data protection ‘site’. The production cluster has been successfully updated to AOS 5.15.1.1 (LTS) but this needed an AHV update to keep everything compatible.. Is is possible / desirable to upgrade the AWS cloud instance AHV ? IIRC it’s not supported to do OS upgrades (MIcrosoft OS anyway) on cloud infrastructure, it’s generally a migration to a new server. Is it possible to put a new AWS remote Nutanix instance in place and connect the backup data ??? Any advice on how to keep the whole Nutanix environment up to date is appreciated.
