Deployment Success

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 co

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 virtual 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 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. 

Hi,I am exploring is there any Nutanix solution can like-for-like replace Riverbed Steelfusion solution?

We have multiple clusters in our nutanix environment and where is NCC upgrade is required. Is there a way to automate this or use API to update NCC? We are on version 3.9.5 and want to upgrade it to 3.10.0.1

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...

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 ? Thanks in advance.

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.

Have you ever wanted to view or change the network configuration of an AHV host but thought that working directly with Open vSwitch seemed daunting or overwhelming? Don’t worry! Nutanix developers have produced an AHV-specific tool that allows for the management of Open vSwitch via a simple interface called “manage_ovs”. This interface has the following features (among others) and even maintains a built-in help system:Viewing current network interfaces statuses Viewing/changing the uplink interfaces configuration Viewing/changing the uplinks bonding configurationThe “manage_ovs” interface is available (as a command) while connected to any of the CVMs of an AHV cluster via CLI. You can find more information about the “manage_ovs” interface as per the AHV NETWO

Nutanix Flow is a security feature which allows for firewall-type protection at the VM layer. However, flow goes another step further in allowing the configuration of “Security Policies” which can govern individual VMs or “Categories” of VMs or (grouped into convenient application-specific domains).Flow is a function of Prism Central and is disabled by default. To enable it, simply access the “Microsegmentation” option from within the “Prism Central Settings” options, tick the “Enable Microsegmentation” check box and click “OK”. To note, you may first want to review the capability checks that Prism Central automatically performs on all registered clusters prior to enablement, which is also possible right from within the “Enable Microsegmentation” dialog box.You can find more information regarding Nutanix Flow as per the

Recently we have introduced a couple of changes in LCM.  HTTPS is a requirement for many enterprise customers. Many of our customers employ strict firewalls, Deep Packet filtering algorithms that only let certain HTTPS traffic through the external gateway. And so today we allow LCM to access the Nutanix portal over HTTPS. (The URL accessed when performing inventory is https://download.nutanix.com/lcm/2.0/)   Nutanix is transitioning from delivering LCM modules as a payload that is associated with an LCM release to delivering them as release-independent repository image module

Do I need to arrange for a downtime for an upgrade? How long does the process takes? If you are planning for an upcoming upgrade and have these questions, look no more:At Nutanix, upgrades are always designed to be done without needing any downtime for User VMs. Before every upgraded it is recommended to go through the Prerequisitesto avoid any issues in upgrades. This document is intended to explain a bit about how each upgrade work and to share some useful best practices for administrators.Is downtime required?

Hi allI use the v2 Prism Elements API to clone a VM from a Protection Domain Snapshot.It seems to work and the VM is created (cloned) correctly.However: The new VM always has the Prefix “Nutanix-Clone-”.The values i pass via vg_name_prefix and vm_name_prefix are simply ignored. In the Web UI (using the v1 API internally) it works fine.Please see the attached screenshots of the Web UI and the API call. Thanks in advance!

In Nutanix Hardware, the IPMI (BMC) keeps track of hardware-related events using the Event Log/System Management Feature. If there is a hardware event that needs to be dealt with, Prism will create an alert and send you an email if Alert Email Configuration is set up. However, there are still other events in IPMI that can be useful.For example, a power button assertion, a chassis intrusion, shutdown related events, or session audits (failed login attempts) will be logged by the IPMI events logs and can be forwarded via email using SMTP.If you may be interested in this functionality, check out KB 2581 to find more information on configuring SMTP in the Nutanix IPMI.

I find that the simplest things in life are the most complicated. Snapshot is one of those things, I believe. It is something we, administrators, do not hesitate to use and yet, not many undersand what it is or how it works. Below are a few things out of many. What is a snapshot? A snapshot is a difference. When a snapshot is created its initial size is zero. That is because initially there is no change to capture. Original data is locked. It can be read but it can’t be altered. All the changes are written to the snapshot. That is why and how you can recover the data before the snapshot - because it is still there and is still intact. What is a VM snapshot for? It is a recovery point that is meant to be kept for a brief period of time as opposed to backups that can be stored for months, years or even decades. Why does a VM snapshot file grow in size?

Hello team, I hope that someone can explain to me why, looking to sizer’s recommandations about hybrid configuations, SSD/HDD ratio is not size dependent but form factor dependent. Basically if you select 2 SSD and 3.5”HDD then a minimum 1:1 ratio is possible (SSDx2 + HDDx2) but if you have have SSDx2 and 2.5” HDD then the minimum ratio is 1:2 (SSDx2 + HDDx4). Is it because 3.5” HDD SAS or SATA are usually faster than 2.5”? It’s not about size or hardware vendor, recommandations seems to changes according to the disks form factor only

Hello,   Is it possible to provide for a group of VMs a Metro-Availability (stretched cluster) solution using ESXi (since this feature for AHV isn’t available yet) to obtain 24x7 availability and downtime+disaster avoidance capabilities for certain services) and also provide for the VMs in the stretched cluster or a subset of those VMs async replication to a 3rd site (DR site)?   Understanding that the stretched containers are sync replicated at the container level, would that 3rd site async replication be based at the container or VM level?   Thanks!
