Do you know you can run a individual log collector just for LCM logs if you are having any troubles running updates from LCM?LCM (Life Cycle Manager) Log Collection Utility provides an independent script designed to collect all the important log files necessary to debug any LCM issue.The utility is available in LCM version 2.2 or later by default. It could also be used on earlier versions of LCM.Functionality:Collects LCM log files. Detects if the node is stuck in Phoenix and collects kernel logs. Collects logs for the services with which LCM interacts (Example: Foundat

Are you someone with the following condition? Your Nutanix Cluster has grown so much that it needs to be moved to a different (bigger) network segment (VLAN).  You are daunted by the amount of changes that moving a cluster to a different network space could result in. Have no fear!The procedures are documented as per the CLUSTER IP ADDRESS CONFIGURATION section of the

Nutanix customers using AHV as their Hypervisor often need to evaluate resources being used/consumed on their infrastructure.  One of those factors involved is in calculating how much space has been consumed by one or more Virtual Machines.  It is possible to get granular in this scenario and be able to calculate the amount of space taken up by a VM.  Depending on their environment, it should be possible or feasible for one to print out the space usage in terms of Bytes, KiloBytes, MegaBytes or GigaBytes.I have developed the following string manipulation to be able to get those numbers.  Here is a sample from one of the checks I performed:nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$ acli vm.list | grep 120-Windows-Invent120-Windows-Invent

Hi ,We have Hyper-V running on UCS, Need to expand Storage piece of it , so Can I build Storage Only AHV cluster with 3 nodes and provide ABS volume as datastore ?Please guide other options.

Do you know you can expand Prism central VM from one to three instances to support moreworkloads?If Prism Central is running on a single VM currently, you can expand it to three VMs. This increases both capacity and resiliency of Prism Central (at the cost of maintaining two additional VMs).  To scale-out Prism Central instance across multiple VMs, we can follow steps below: Click Gear icon and then select Prism Central Management from Settings menu Manage Prism Central page appears which provides information about Prism Central Instance.  To expand Prism Central instance from one to three VMs, click the Scale Out PC button to display the Scale Out PC page and do the following:

Hello,i have three nodes configured with nutanix AHV and in the storage container i am seeing 3 containers but one of the containers is not working i can’t even update the setting for it please it has over 21 tb space and i couldn’t use it so what do i have to do to make it available. 

Hi everyone, I need some help.I'd like to see the output of several Prism Element API calls in the Nutanix/ESXi hypervizor environment.curl -ks -u 'user:pass' -X GET 'https://<prism_element_ip>:9440/PrismGateway/services/rest/v2.0/cluster'curl -ks -u 'user:pass' -X GET 'https://<prism_element_ip>:9440/PrismGateway/services/rest/v2.0/hosts'curl -ks -u 'user:pass' -X GET 'https://<prism_element_ip>:9440/PrismGateway/services/rest/v2.0/vms?include_vm_disk_config=true&include_vm_nic_config=true'We are developing a monitoring/reporting tool for multiple platforms. We have recently added support for Nutanix as well. It works fine with AHV but we don't have access to a Nutanix/ESXi config.Thanks and regards,P.

Hi guys, a non technical question about a customization option that I can’t find anywhere. I have two Prism Central used for Synchronous replication. To Identify them at first sight I have customized title and colors of the login page. It was a bit disappointing to not find the customized name on the browser tab or at least on the menu bar title. Even after editing the cluster params to give a name to the PC cluster (only one VM as for now) the name stick on “Prism Central” on the tab and “Prism” on the menu bar.Considering I’m working on a Synchronous replication and that all the objects involved have the same name (Protection Policies, Recovery plans, categories), sometimes i found myself working on the wrong Prism Central. It would be easier to have the PC name always visibile. Any idea? Thanks in advanceil_gianK’ 

Upgraded PC to 2020.7 and ncc to 3.10.1.  Now getting the warning:Possible CauseThe current feature capabilities of Prism Central require resource on the Prism Central VM to be increased for optimum performance. RecommendationIncrease the resource of the Prism Central VM. Please refer KB-8932 for guidance. I am at 6 vCPU and 32 GB RAM for PC VM.  Not getting too far with support.  I was wondering if others have seen this issue.The KB article mentions “large” and “small”.  I don’t remember setting PC size.  How does it know if it is large or small?  Mine thinks it is large, but I only have around 200 VMs in 3 Clusters.  Only using a single PC, not scaled.

Hello,How many ssl certificate we can use in nutanix cluster. (1, 256, ...)Thank you.

Hello, i have deployed a banch of VM’s on nutanix AHV nodes and now i wanted to access those VMS with my laptop using remote desktop connection but after i have allowed the remote access on the VMs it keep showing me this error. 

Dear Team,We purchased NX-1265-G6-4114-CM (3 Node)  but customer refuse to take and this node register with this customer. we want to sell this node to my other customer.I want to know how we can change the customer name,basically how to change ownership one customer to another customer.really appreciate if someone  help us.

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.

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.
