Hi all !I changed the format of Replication Factor 3 to 2 of my nutanix cluster, everything went well and without problems of my cluster but I have 2 doubts.I'm still seeing this error regarding extent groups and Oplogand the other doubt I have if I change my Replication Factor format from 3 to 2, my Fault Tolerance changes to 1 or is there a command to change my fault Tolerance to 2? I would greatly appreciate your help to correct errors or have more knowledge about nutanix.thanks 

Good morning, Is there any way to give specific right to a role for group of vms?? Thanks in advance

NOTE: If you are running AOS 5.11.x Please upgrade to AOS 5.11.1.2 or higher before enabling the Remote Support TunnelWhat is the Remote Support TunnelThe Remote Support Tunnel allows Nutanix SREs and Engineers to access a cluster via a Secure SSH Tunnel.We can also send a public SSH key to allow access without the need for the cluster password to be exchanged. Enable the Remote Support Tunnel In Prism, go to; Settings, by clicking the gear wheel or from the Dashboard selection Select Remote Support Enable for n hour(s) (maximum of 24 hours)After 5 - 10 minutes, go back or refresh the Remote Support setting screen to see the Status. The Connection Status should be reporting “Success”.    If the status is reported as Disabled, (as seen below), please review the following Knowledge Base Article for Troubleshooting options. Nutanix Remote Support Tunnel Troubleshooting Guide

Hello,I’m trying to implement custom monitoring with Zabbix regarding the Alerts.I’ld like to put custom alert based on Nutanix alert title such as : Cluster does not have enough free space to tolerate {num_node_failure_limit} node failure(s)snmpget -v 3 -u zabbix -l authPriv -a SHA -A ‘XXXXXXXXXXXX’' -x AES -X ‘XXXXXXXXXXXX’' 172X.X.X ntxAlertTitleBut i have the following error : NUTANIX-MIB::ntxAlertTitle = No Such Object available on this agent at this OIDThis kind of things are only based on trap message ? Regards, Damien

I noticed that this web page has changed.https://www.nutanix.dev/api-reference-v3/Old version can copy the response, like this picture.I need it in this format.How can I access the old version of the web page? Or how can i copy the response in this format?Thanks. 

If I want to call this api for a vm， I must add this vm into a protection domain, and take a snapshot for this protection domain.  Then, I can get the vm’s disks’ snapshot file path , like this :  /<storage_container_name>/.snapshot/<number>/<id>/.acropolis/vmdisk/<vm_disk_id>I can use this file path to call this api successfully.But, a protection domain maybe contain many vms, if I take a snapshot for a protection domain, all vms in it will take a snapshot,  I just want to take a snapshot for one vm of them. if I take a snapshot for a vm directly, I will get the vm’s disks’ snapshot file path, like this:  /<storage_container_name>/.acropolis/snapshot/<snapshot_id>/vmdisk/<vm_disk_id>.But this filepath is invalid for this api. like this question:https://next.nutanix.com/discussion-forum-14/get-error-code-400-when-use-v3-api-post-data-changed-regions-40363  I want to take a snapshot for one vm, and don’t affect other vms, and I can use this snap

Hello,I have 3 nodes from Fujitsu, that are preconfigured with AHV, at discovering with standalone foundation is only see nodes 2 and 3, the same on Foundation Applet.Yesterday the nodes was discoverd corectly untill the cluster formation proccess i had some other problems with the same node (the error was “Critical updating cvm memory and hostname configuration failed. Timeout waiting for the CVM to come up), after i retried the steps at the discovering the nodes step for this node i had the error “This node is not discovering. Retry discovery or convert to manual node” Now i am trying via a Standaloe Fundation that is running on Virtualbox and this node is not discovered.Can you please help me with this problem?Kind regardsOctavian

If you ever need to present storage to your Guest OS directly via ISCSI here is some useful information for you. To provide access to cluster storage, Volumes utilizes an iSCSI data services IP address to clients for target discovery which simplifies external iSCSI configuration on clients. This iSCSI data services IP address acts as an iSCSI target discovery portal and initial connection point. Nutanix does not recommend configuring iSCSI client sessions to connect directly to Controller VM IP addresses. The data services address is owned by one Controller VM at a time. If the owner Controller VM becomes unavailable, the address moves to another Controller VM, ensuring that it is always available. This IP address is also used as a cluster-wide address by clients configured as part of Nutanix Files and other products. This IP address: Should be in the same subnet as the cluster Controller VM IP eth0 network interface addresses Helps load balance storage requests Enables path optimizati

At title - I would like to see how a particular VM is performing with dedupe and compression if possible? Cheers,Steve

 By default, Life Cycle Manager (LCM) automatically fetches updates from a pre-configured URL. If LCM fails to access the configured URL to fetch updates, you can configure the LCM to fetch updates locally to upgrade Calm and Epsilon. Perform the following procedure to upgrade Calm and Epsilon at a dark site.Ensure that the LCM version is 2.3 or above.Procedure Set up a local web server that is reachable to your Calm VMs.You will use this server to host the LCM repository.   Use the following steps to set up your LCM repository: From a device that has public Internet access, go to the Nutanix portal and select Downloads > Calm. Next to the LCM Dark Site Calm on ESX Bundle entry, click Download to download the latest LCM framework tar file, lcm_dark_site_bundle_version.tgz. Transfer the framework tar file to your local web server. Extract the framework tar file into the release directory.The following files are extracted into the release directory. master_manif

Calm on ESXi 3 Tier (Calm VM) is a standalone VM that you can deploy on ESXi hypervisors and leverage calm functionality without the Nutanix infrastructure.You can deploy Calm using the image available on the Nutanix Support Portal - Downloads page and start managing your applications across a variety of cloud platforms. This eliminates the need for buying Nutanix infrastructure to use Calm. Supported ESXi versions: 6.0.0 and 6.7 (vCenter version 6.7) Scale-out of Calm VM is not supported. Calm Version is 3.0.0.1. Policy engine enablement is not supported There are two available options. Deploying Calm using vSphere web-client Deploying Calm using vSphere cli.  1.

I was able to build a Nutanix Move server on an AHV and move VMs from Hyper-V onto the AHV.I wanted to shut down the Nutanix Move server since I won't be using it for a while, so I logged in from the console(I found out when I logged in that it was Alpine Linux.) and ran the "poweroff" command, but I got an error "Operation not permitted".How can I shut it down from the console? 

Hello Team,Greetings!I am checking to see if we can access Nutanix compatibility matrix https://portal.nutanix.com/page/documents/compatibility-matrix without needing to register Nutanix Product. Like as a partner or a regular user who do not have Nutanix products but want to check compatibility, how to do it?

Hello everybody,I was unsuccessful to boot from a SATA CDROM in an AHV VM on different Nutanix-cluster with the same AOS 5.15.4 LTS version.Allthough I explicitly selected to boot from the SATA CDROM, the VM says ‘Could not read from cdrom (Code xxx) and instantly jumps into 2048 game (what the heck).As soon as I switch to an IDE CDROM, the system boots properly.Is this a bug in AOS 5.15.4 LTS ?ThanksDidi7

Hi there,I need explaination about vCPU usage :My CPU Model is Intel(R) Xeon(R) Silver 4208 CPU @ 2.10GHz (8 core, 16 thread)  I have two socket per host So 2 x 8 = 16 cores and 4200 Mhz (base freq) / 6400 Mhz (max turbo freq) So 32 vCPU (16 cores x 2 = 32 thread with Hyperthreading) A VM use 6 vCPU and 1 core Prism report for this VM, 97% of CPU usage97% of what ? Is that 6400 / 32 x 6 = 1200 Mhz ?? The half a physical CPU ?How that calculation is made ?Thanks,Jerome

I’ve been trying to download the latest version of Prism Central through Prism and consistently fails. I then downloaded the binary and metadata file but they also continue to fail to upload through Prism after various progress. I checked that there’s at least 10GB of  free space in the /home directory - are there any logs that I can look at to troubleshoot further?
