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
Enable or disable console support for a VM with only one vGPU configured. Enabling console support for a VM with multiple vGPUs is not supported. By default, console support for a VM with vGPUs is disabled.To enable or disable console support for each VM with vGPUs, do the following: Run the following aCLI command to check if console support is enabled or disabled for the VM with vGPUs.acli> vm.get vm-nameWhere vm-name is the name of the VM for which you want to check the console support status.The step result includes the following parameter for the specified VM:gpu_console=FalseWhere False indicates that console support is not enabled for the VM. This parameter is displayed as True when you enable console support for the VM. The default value for gpu_console= is False since console support is disabled by default.Note: The console may not display the gpu_console parameter in the output of the vm.get command if the gpu_console parameter was not previously enabled. Run the followi
AHV hosts support GPU pass-through for guest VMs, allowing applications on VMs direct access to GPU resources. The Nutanix user interfaces provide a cluster-wide view of GPUs, allowing you to allocate any available GPU to a VM. You can also allocate multiple GPUs to a VM. However, in a pass-through configuration, only one VM can use a GPU at any given time. Host Selection Criteria for VMs with GPU Pass-Through When you power on a VM with GPU pass-through, the VM is started on the host that has the specified GPU, provided that the Acropolis Dynamic Scheduler determines that the host has sufficient resources to run the VM. If the specified GPU is available on more than one host, the Acropolis Dynamic Scheduler ensures that a host with sufficient resources is selected. If sufficient resources are not available on any host with the specified GPU, the VM is not powered on.If you allocate multiple GPUs to a VM, the VM is started on a host if, in addition to satisfying Acropolis Dynamic Sche
Memory and CPUs are hot-pluggable on guest VMs running on AHV. You can increase the memory allocation and the number of CPUs on your VMs while the VMs are powered on. You can change the number of vCPUs (sockets) while the VMs are powered on. However, you cannot change the number of cores per socket while the VMs are powered on.You can change the memory and CPU configuration of your VMs by using the Acropolis CLI (aCLI), Prism Element (see Managing a VM (AHV) in the Prism Web Console Guide), or Prism Central (see Managing a VM (AHV and Self Service) in the Prism Central Guide).Memory OS Limitations On Linux operating systems, the Linux kernel might not make the hot-plugged memory online. If the memory is not online, you cannot use the new memory. Perform the following procedure to make the memory online. Identify the memory block that is offline.Display the status of all of the memory.$ cat /sys/devices/system/memory/memoryXXX/state Display the state of a specific memory block.$ g
In a traditional three-tier architecture, application and database administrators often work with storage administrators to create a custom storage design to suit their environment, which includes designating the RAID level and block size for different types of files, such as database tablespaces or log files. This process can become cumbersome to manage, especially if there are multiple databases. Nutanix eliminates the problems associated with choosing the optimal RAID and block size. Once you create a VG with the required number of vDisks for your database or application, you’re ready to deploy. The following table outlines the recommended minimum disk layout for a database such as Oracle. For other workloads please refer to the specific application’s best practices guide.There are two ways to create vDisks on Nutanix for your VMs: Nutanix native vDisks. Nutanix volume groups. Nutanix Native vDisksThe Nutanix native vDisk option simplifies VM administration because it doesn’t req
NOTE: If you are running AOS 5.11.x Please upgrade to AOS 22.214.171.124 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.

We are moving from VMware vSphere 6.0 to Nutanix Cluster AHV (Nutanix is our Hypervisor). The question is previously we could select console in VMware and make a 2nd connection to the VM (Server or workstation) with out somebody previously logged i without logging the 1st user off. Is the Nutanix Console different than the VMware Console?
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.

Use LCM to display the software and firmware versions of the entities in the cluster.ProcedureIn Prism Central, click the gearbox icon to open the Settings page and select Life Cycle Management in the sidebar. Prism Central opens the Life Cycle Manager page. Click to enlarge Click Options > Perform Inventory. If you do not have auto-update enabled, and a new version of the LCM framework is available, LCM shows a warning message: Click to enlarge Click OK. The LCM displays all discovered entities. To view the current Calm and Epsilon versions, click View All. Click to enlarge The entity shows the current version, as well as the date and time of the most recent update.

You can upgrade to newer versions of Calm without performing a VM upgrade. Upgrades to most minor releases and few major releases are done using the LCM method.LCM performs inventory and Calm/Epsilon upgrade operations fail using the default LCM URL. The workaround is to replace the LCM repository URL to http://download.nutanix.com/lcm/saas under the LCM > Settings.To upgrade Calm VM using the LCM method, do the following: Procedure Click Administration > LCM to open the LCM page. Click Perform Inventory.A confirmation window appears. Click Proceed.The Perform Inventory process can take several minutes depending on your cluster size. Once completed, you can view the available updates in the Software page. Select the check-box next to the Calm VM version that you want to upgrade. Then, click Update.Note that the Epsilon check-box also gets selected. Epsilon is the orchestration engine used by Calm. A confirmation window appears.Once the update process begins, it cannot be s

Can't we access Nutanix Compatibility Matrix / Interoperability page without registering Nutanix Product?
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?
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?
We have 3 node HPE DX380 deploy nutanix recently.After 2 - 3 days, i saw the physical disk show bad disk suddenly and no flush light in physical disk LED light. When i login iLO port, the storage is good and no error. When i login PRISM, look the disk is Red and show “The drive has failed”. When i unplug it and plug it again, and re-partition it, seems back normal, but i concern the new server have this error suddenly so want to create nutanix case, but when i create case with input HPE serial number, it is not allowed, so i would like to ask how to create Nutanix case for HPE DX380. Many thanks.
Firstly I am new to Nutanix and still have a lot (everything?) to learn on the subject. I have a single Nutanix cluster running AVH and a number of VMs in production, when the cluster was setup (by a contractor) a Prism Central trial was also setup. To be honest, with a single cluster I have not found any real need to Central so now the trial is up I was wanting to decommission it.The PC VM is also being reported as a ‘bully’ in the cluster so another reason to get rid. Obviously I could just switch it off, but I’m sure that there is more to it than that to safely and cleanly remove the PC instance. Considering my newbie status does anyone have any specific articles they know of, or even better some instructions I can follow to safely and cleanly remove PC from the environment please?

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
