How It works

Prism Central is a centralized management tool that runs as a separate instance comprised of either a single VM or a set of VMs. This multi-cluster view, allows you to monitor and manage multiple clusters through a single web console. If you would like to deploy a Prism Central instance, you can either follow the 1-Click method or the manual method.   Do you have a Prism Central(PC) instance deployed in your environment and are planning to upgrade it? Here is the second installation of the

Starting from AOS 5.10.2 and newer, if you run the ‘cluster status’ command, you may see that there is a new service running on the cluster called Xtrim. That service was not present before 5.10.2: Xtrim is the service that is going to improve the performance of the cluster. If we look a bit deeper, it improves the write performance by periodically trimming the SSDs. In Nutanix all the disks are passed-through from the host to the CVM and the CVM is managing the disks, so the Xtrim service running on CVMs is doing the trimming of the physical SSDs.  

Hello community, Maybe one of you can assist me for a report of cluster usage. I need a report which gives me the usage of all VMs in a cluster. But I need this information for every VM separated. In the analysis page I can only create a chart for on VM and with over 600 VM this take a long time... I need for a time span of the last 3 month the following information of the VMs IOPS (min,max, avg) RAM (min,max,avg) CPU (min,max,avg) Is it possible with the analysis page or with an cli command ?

Quick tip for a hump day. Rushing in to check something quickly on the IMPI. Can’t be bothered with the Web interface. Jumping into a CVM CLI only to find out that the ipmitool isn’t working and the error isn’t helpful. Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directoryGet Device ID command failedUnable to open SDR for reading Good news is the IPMI is most likely fine. Chances are all you need to do is to use a few extra keys as part of the ipmitool command. Remember that for all calls executed from a CMV the ipmitool has to authenticate with the IPMI and the calls are traversing the network technically even if it is only a virtual switch. KB-1345 Using ipmitool on the CVM gives full command syntaxis and is rich with examples. For Dell hardware refer

Hi Expert, I would like to seek your assistance with regards to the capacity planning for Nutanix. Our prism cluster is not license so we can’t use the built in capacity planning tool. Is there any other way where i can get the historical value of CPU, memory and disk per AHV cluster? I’m a little bit new in Nutnix so I’m still curving up my skills. TIA

Hi I m working to automate the planned failover of protection domain. We are very familiar with powershell and so I m wondering what is the cmdlet to retrieve the status of protection domain (Enabled- in sync, disabled , pending ...) ? I searched on the documentation but i didn’t find it Thanks

Recently my customer is configuring snmp monitoring in their infrastructure to monitor their nutanix clusters. As their Administrators are trying to capture keywords from the snmp traps, they found that the snmp trap messages and the alerts messages found in the web console guide are different. Is there a document which can help to indicate what are the exact snmp trap messages /format for the different alerts sent?

This article covers the first component in a Generic Nutanix Environment Upgrade cycle - NCC. This is the first installation of the component-wise Upgrade guides series. Check out this article for a quick walk-through of the overview for a cluster-wide upgrade cycle.   Nutanix Cluster Check (NCC) is a framework of scripts that can help diagnose cluster health. NCC runs on clusters and on Prism central. The workings of NCC on PC and the cluster are pretty much the same except the checks involved in the respective modules are different. NCC also includes the Logbay plug-in. Logbay is the utility used to collect logs from Controller VMs and hosts that are useful for troubleshooting issues.    NCC Guide for the latest version (as of 7th of July, 2020) can be found

Hello, Very new to the Nutanix CLI and I am doing a lot of PD testing to a DR Cluster and restoring them with the default prefix. I was wandering if someone could help me with a script to shitdown all VM’s with the name starting ‘Nutanix-Clone-”. I found this : for vm_name in `acli vm.list power_state=on | grep -v ^'VM name' | awk '{print $1}'`; do acli vm.shutdown $vm_name; done which is excellent but Im not sure how to further filter it by VM name? Any help appreciated. Note: Id also appreciate any help with a script that then deletes any VM and associated snapshot starting with ‘Nutanix-Clone-’ - doing 80 or so through the web console is hard work. Thanks for you time, Aaron

hi team, i want to ask something, in my understanding nutanix can tolerates 1 node failure if I use rf 2 where the data will be replicated into 2 pieces, what happens if I have 10 nodes, how much nutanix can tolerance of node failure at the same time? it still tolerates only 1 node failure or any other mechanism? I am confuse after read this kb https://portal.nutanix.com/page/documents/details/?targetId=Web-Console-Guide-Prism-v5_17%3Aarc-host-failure-c.html

Hello guys,  I am a new Nutanix user and I wonder something about snapshots. I created two scenarios in  AHV. In the first scenario, I created a VM, created a PD with this VM and deleted the VM in Prism.I restored one of the snapshot and was able to restore the VM. Question : Will the PD be able to still work despite that the VM was restored with the same name (obviously some ID might have changed ?!).  In the second scenario, I created a VM but this time without PD. I created a snapshot using take snapshot within the VM options in Prism. Then I deleted the VM (with the option to delete snapshots not selected). I was able to see the snapshot using acli but the only way to recover this type of snap would be to specify the VM name which obviously does not exist in Prism anymore. Question : How can you recover from this situation ?  Sorry if the questions sounds stupid or if it has been answered before.

When you run ESXi hypervisor on Nutanix you may get a question: should I install VMware tools or Nutanix Guest Tools (NGT) or both? Are NGT and VMware tools compatible between each other? The answer is yes, they are compatible and can be both safely installed on the same virtual machine. If you install NGT in guest VMs, you can use the following advanced features (NGT applications): File Level Restore CLI Nutanix VM Mobility VSS requestor and hardware provider for Windows VMs Application-consistent snapshot for Linux VMs You can read in more details about the NGT here. VMware tools in turn has different features and a different purpose. Installing VMware Tools eliminates or improves t

Hi Experts, Would it be possible to do a mass migration from AHV Cluster to another AHV cluster? My objective is to free up the resources of my current AHV cluster and move other VM’s to the newly build AHV cluster. Appreciate your advice and best approach.

Hi Probably a very simply question and more of a sanity check. I have many Win 0S servers to perform OS upgrades on. Looking to do the following..   Ensure VM has ngt installed Power down VM Clone VM Power up clone, perform OS upgrade 2 weeks later delete original VM   I assume the powered down VM doesn't actively contribute to CPU usage but storage will be ring fenced. Therefore I will see storage decrease whilst I'm upgrading VMS and before I delete the original.   Any disadvantages to making the cloned VM my new production VM rather than the other way round?   Is it ok to delete the original VM which the clone is being based off?      

I’m running PC Scaleout (5.16.1.2) on ESXi and need to migrate all 3 nodes to a new datacenter cluster and datastore (same vcenter).
