Deployment Success

I have read that it is only supported using ESXI. If so, what are the other ways to automate the failover.

We are excited to announce the release of Nutanix Move 3.5.0 Adopting new infrastructure platforms often requires a migration of pre-existing systems. Nutanix Move simplifies bulk migration of existing VMs to Nutanix, eliminating the friction associated with onboarding new IT infrastructure. Businesses can quickly leverage the full potential of Nutanix Enterprise Cloud with near-zero VM downtime during the migration from vSphere ESXi, Hyper-V and Amazon AWS to Nutanix AHV and vSphere ESXi to ESXi on Nutanix. Move also support migration of VMs from Nutanix AHV to Amazon AWS. Nutanix Move 3.5.0 is released and the bits are available on the Portal for Download. Move 3.5.0

This article describes how to rename the CVM entity in Prism within the AHV environment. This does not change the hostname of the CVM displayed in a console/SSH session as the hostname is a value configured within the CMV OS and is independent of the Controller VM name entity recorded in the Prism entity DB (Insights Data Fabric). It is the same name as in CVM’s XML definition on the AHV host. It can be checked by listing VMs on the host. The name displayed is the name that is shown in the Prism Wen console. Starting from AOS 5.10.10, 5.15 and 5.16, change_cvm_display_name script is available on CVM that can be used to change the di

Hey all,   At the suggestion of some people, sharing this video that I’ve created that goes through the VMware upgrade process using Nutanix 1-click functionality. Check it out if you’d like. Apologies in advance for the poor quality - it was the best way for me to hide any confidential info on screen. Cheers!

There may be instances where you'll receive the following alert in your environment      "Cassandra on CVM x.x.x.31 is now detached from the ring due to Node was down for a long time. Node detach procedure done by x.x.x.41."   Before understanding the alert, let's first understand what is Cassandra and the ring-structure?    Cassandra stores and manages all of the cluster metadata in a distributed ring-like manner based up

We make use of a lot of the FIQL filtering in our automation to pare down results from various REST calls. However, it seems that while filtering on things like category_name or category_value work just fine with an ==, they don’t seem to work with an !=. Is there a way to do an inequality filter, specifically with v3 of the Prism Central API?

Here is a tip on how to reset the password for Nutanix Prism local user. The guide applies to Nutanix Prism Central as well. There are two ways. 1. Using Prism interface Log in to Prism Element with domain user and  go to User Management Prism user management   From the user's window choos

Hi, I have a question, is it possible to exclude a timeblock from syncing? We want to migrate a machine, wich may not delay in the nigthly schedules. We are now running version 3.4.1

Nutanix Hyper-Converged Infrastructure brings together the power of compute, storage and networking in just one node.   There might be situation where you’ll get queries in regard to mixing different components in NX- Hardware   For example   Are there any NIC restrictions?   Are there any Storage restrictions?   Can I have a hybrid SSD/HDD node and all-SSD node in the same cluster?   Are there any restrictions related to the DIMM

Hi Does anywhere can be find the ESXi version and AOS version interoperaability or compatibility? I found that in the foundation iso_whitelist file, there is some ESXi version has min_nos requirements. but differnet OEM partner has different requiremnts. But from VMware compability web site. ESXi is compatibility with most of the AOS version as the link. For example: ESXi 6.5 U3 --Dell has no min_nos requirements --Lenovo min_nos is 5.10.6 --Fujitsu has no min_nos requirements --HPE min_nos is 5.10.7 So if it is old enviroment, Does the ESXi version must meet the AOS version requirement in the whitelist?

Secure Boot is specifically designed to prevent a malicious boot loader attack and has been the most widely accepted approach for both Windows and Linux. Secure Boot is supported by major hardware and hypervisor vendors.    Windows introduced a new specification called Unified Extensible Firmware Interface (UEFI) that connects the computer’s firmware to its operating system (OS). UEFI is now part of an open-source forum UEFI and is expected to eventually replace BIOS.   In order for Nutanix to fully support secure boot, Nutanix binaries are now signed with keys that the hardware trusts.   The Nutanix public keys will either be available by default in the hardware or a customer would need to manually obtain Nu

There are 3 types of Nutanix nodes:    An HCI Node is the most common kind of node. It is heavily equipped with all three components: processing capacity (CPU), memory (RAM), and data storage capacity. An HCI node can run any kind of supported hypervisor. A Storage Node only runs the Nutanix AHV hypervisor. These nodes have a bare minimum of processing and memory capacity however, as the name suggests, have plenty of storage onboard. A Compute Node only runs the Nutanix AHV hypervisor. Logically, th

All, I have a 6 Node 1065 system in 2 blocks.  Recently one of the CVMs (node 2, block A) crashed.  When rebooted it was just going in loops.  When diagnosed it seems the SSD (not the SATADOM) had failed and we replaced it.  When we try to boot the CVM, it still just loops. We were told to boot that node with Phoenix which the cluster provided me for download.  I do that and it doesn’t load Phoenix and gets errors instead.  I’m looking for a suggestion of how to get the node back to 100%.  At this point (and throughout) the ESXi on the SATADOM has booted fine and I guess if I didn’t care about the storage side I could just ignore this but I’d like the system to be fully healthy. Any suggestion about how to get the CVM working again would be appreciated. Thank you Johan

What is the difference between the Redundancy Factor and Replication Factor? Redundancy factor 3 is a configurable option that allows a Nutanix cluster to withstand the failure of two nodes or drives in different blocks. By default, Nutanix clusters have redundancy factor 2, which means they can tolerate the failure of a single node or drive. The larger the cluster, the more likely it is to experience multiple failures. Redundancy Factor 3 requirements: Min 5 nodes in the cluster. CVM with 32GB RAM configured.

VDi (Virtual Desktop Infrastructure) is one of the earliest applications that was used in hyper-convergent  systems. The closer the storage to the cpu and memory the better the performance. The plugin provides the means for getting more information on Citrix director from Citrix generated desktops running on a Nutanix cluster. Citrix also has its own plugin that can be used. This conversation is about nutanix provided plugin and how to install it. Nutanix AHV Plug-in for Citrix Director creates customized reports for the following VM-level performance statistics: VM IOPS VM I/O Bandwidth VM Average I/O Latency Nutanix AHV Plug-in for Citrix Director gets the data directly from the Nutanix AHV hosts to generate performance statistics of the virtual machines.

The NCC health check idf_db_to_db_sync_heartbeat_status_check verifies the consistency of data replicated from the Source Cluster to the Replica Cluster. IDF is Insights Data Fabric. A DB that contains data about all the entities in the cluster. And it has to be synced between PE and PC. For the purposes of the check, the source cluster is where the check is run from and the replica cluster is the DB instance that is compared against. This check returns a FAIL status when the heartbeat sync time between database on the source cluster and database on the replica cluster crosses a predefined threshold value (10 minutes, by default). 

Currently, we have two types of releases: Short Term Support (STS) releases that have new features, but also imply regular upgrades. Long Term Support (LTS) releases that are maintained for a longer duration and provide primarily bug fixes for an extended period of time on a particular release family. Depending on your choice of the type of the release i.e. LTS or STS, you can identify the type that has been currently installed using one of the following methods:  By looking for is LTS fiel

If you've set up a new Nutanix cluster, you've seen the popup during the initial login that asks if you want to disable Pulse (not recommended). Yes, that one.   So you may be wondering, what will it send and why would I want to enable this?   The purpose and scope of Pulse data is cluster health monitoring. The data sent to Nutanix includes hardware, software, and firmware version information, storage usage and configuration details, resiliency status, CVM health status information, and some limited detail about VMs on the cluster. In the Pulse settings UI in Prism you have the option to enable or disable additional support information such as entity names, so you can keep those user-friendly names private if needed.   More complete detail on what gets included in Pulse data transmissions can be found in t

I’m running into an issue with my script to deploy and setup a new VM in AHV.  The part to check for and install Windows Patches can take a while and sometimes I come out of that routine and I’m no longer connected to Prism Element. I connect with Connect-NTNXCluster… I’ve seen where you can use $TestConnect = Get-NutanixCluster and then check the .IsConnected parameter. However in my testing, I last connected yesterday and when I run that this morning it still shows .IsConnected = True so it doesn’t seem like it gets updated. I’ve also changed the Prism Element GUI settings to a 2 hour timeout but still seems like after way less than that I am no longer connected.  Does that apply to script connections as well? What is a good/reliable way to test if I'm still connected (outside of trying a command and catching the “unauthorized” error)?   Thanks!

Let's say you just upgraded your AOS to the latest version and now  you are receiving this alert in your environment.   "Disk space usage for root on Controller VM has exceeded 80%"   The Nutanix CVM is what runs the Nutanix software and serves all of the I/O operations for the hypervisor and all VMs running on that host.   Not sure how to bring the root partition on the CVM below 80% and which document to consult to?   The following knowledgebase articles might help you in resolving the alert.   KB-7604

Let's say for example we have multiple VLANs in our environment to logically segment the traffic.    We need to configure the network interface accordingly as we might need a VM to be VLAN aware.    Before understanding the method to configure this, let us understand the difference between trunk and access modes.   An access port sends and receives untagged frames (i.e. all frames are in the same VLAN)   A trunk port supports tagged frames and thus it all
