Deployment Success

 Hello All, I was trying to deploy Nutanix AOS 5.15.1 and HyperV2016 on 03 Lenovo HX-2321 nodes using Foundation 4.5.4.At the first time, the deployment failed with this message : "Fatal running pre-install sanity tests" for each of the 03 nodes. Please see below all the related log messages :==================================================================2020-08-18 17:02:12,832Z DEBUG Setting state of <ImagingStepValidation(<NodeConfig(10.105.254.200) @b390>) @be70> from PENDING to RUNNING2020-08-18 17:02:12,838Z INFO Running <ImagingStepValidation(<NodeConfig(10.105.254.200) @b390>) @be70>2020-08-18 17:02:12,845Z DEBUG Cache MISS: key(<function common_validations at 0x0399D2B0>_()_{'global_config': <foundation.config_manager.GlobalConfig object at 0x0518B890>})2020-08-18 17:02:12,845Z INFO Validating parameters.

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

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

What is Fault Tolerance (FT)?FT is how the system ensures that both user VM data and cluster infrastructure data is protected from failure. What are Fault Domains?Failure scenarios can be thought of in terms of fault domains.  There are four fault domains in a Nutanix cluster:Disk Node Block RackThis article focusses on Rack Awareness. Rack failure can occur in the following situations:All power

NCC alert showed following issue and followed KB 2050 Detailed information for cvm_startup_dependency_check:Node 192.168.x.x:FAIL: Failed to open vmx fileRefer to KB 2050 (http://portal.nutanix.com/kb/2050) for details on cvm_startup_dependency_check Based on observation the datastore name used by node had pre-fix which caused the NCC alert to failsChanged NTNX-local-ds-17FM37420063-B (1) to NTNX-local-ds-17FM37420063-BThis helped to resolve the NCC alert message. 

Is there a way with NTNX Powershell cmdlets to collect software inventory data for all registered clusters? Something like;Cluster Name AOS version Foundation version NCC version Hypervisor versionThanks!

Hello all,I have managed to configure the 3 node cluster with AHV and all of the were working at first but after 2 days one cvm has been down can’t communicate with others.i have tryied to fix it but i couldn’t.both the AHV and host ip does reply for ping but the CVM dosen’t.i have run the NCC and got the log but it only says there is a duplicate ip but when i check for duplicate ip there is no duplicate ip in the configuaration. i have attached the NCC report incase you want to see it. Any help will be greatly appretiated.

Hello, i have a running nutanix 3 node cluster in my environment all is good. the problem is when i create a VM and launch it i the OS starts with without the network adapter i have added 1 Disk and also 1 virtio and also the OS in separate disk configuration. i have the screenshot of the configuration please tell what did i do wrong. 

What are the commands to shutdown and delete guest VMs?

Hello all,Is it possible to install the french version of Windows server 2016 using nutanix foundation ?I wonder this because in the iso whitelist, I only see english versions of windows server 2016 as supported versions.Thanks.

Good afternoon, all!I’m setting up a Move project to migrate some VMs from Hyper-V to AHV. In the 3.6 Move user guide, it says “You need PowerShell version 4.0 or later.” Do we need it on each source VM, on the HV hosts, on the management workstation, or all three?Thanks to all for looking! Gregg

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?

Do you want to import Third Party Appliances on AHV and wondering about following questions?Is my Third-Party Appliance compatible with AHV? What is supported and un-supported? How will I migrate my Appliance to AHV?We have multiple options that can be used to deploy Third Party Appliances on AHV. Third-party application vendors provide different applications or appliances that are certified to run on AHV.Here is the full current list of such applications: Compatibility MatrixNote:

Hello!We have 5 node RF3 cluster. I tried shutting down 2 of 5 node at a time. Cluster stays online, but rebuild never happens. Is it normal? Should 5 node RF3 cluster rebuild after loosing 2 nodes? Can it survive loosing 1 more node after already loosing 2 (only 2 of 5 stays online)? 

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?

What is Nutanix Collector ?It is a desktop application that collects cluster statistics from your VMware or Prism cluster. This output can then be viewed in Nutanix collector or can be downloaded as an Excel file. You can then upload these Excel files into Nutanix Sizer to size and predict future workloads or just to collect statistics on current usage.Nutanix collector enables you to collect data in following methods: You can choose between: Data center/Cluster or All entities registered to vCenter Single Cluster or all entities registered to Prism Ce

Hi All, Wondering if anyone has scripted the addition and configuration of nic’s for VM’s that have failed over in a PD? Noticed a few posts from a few years ago but seeing if approach has changed at all. My approach (no script yet): Check which PD’s have become active at remote site to get list of vm’s grab mac and ip info from a mainted csv (plan to use dhcp reservations on dhcp server) Add nic’s with info grabbed from csv Perform some DNS updates Power on Interested to know what others are doing and any feedback on my approach would be appreciated. Thanks! -PeteP

By default, the Prism Central login page includes background animation, and users are logged out automatically after being idle for 15 minutes. You can disable the background animation, change the session timeout for users, and override the session timeout completely.Some points to note:1. This setting is not persistent. In other words, if the Prism service restarts, this setting is lost and must be disabled again.2. Disabling or enabling this setting in Prism Web Console does not propagate to Prism Central or vice versa. The setting must be disabled in Prism Web Console and Prism Central UI separately.3. The timeout interval for an administrator cannot be set for longer than 1 hour. For more information on the details and steps, click here. 

I wonder if there is any limit on the number of NICs (VLANs) in a guest VM using AHV \ AOS?As well as, what would be the implications of a VM with multiple NICs, for example, over 20 NICs.

Hi All An oddity going on here I have upgraded but I still get an alert say the upgrade is available Info : Bundle el6.nutanix.20170830.395 is available for AHV upgrade. My Cluster Version : el7.3-release-euphrates-5.15-stable-4fbdd4d9de331230bb468b3549f530e80ab53bb9 Any ideas how I can correct (if there is a problem) or check what is going on? Thanks Eric
