Quick tip of the day. Did you know that you can integrate IPMI with the Active Directory?   Note: The default timeout is set at 0, which results in an error message HTTP 500 - Internal Server Error. Make sure to update it to 10. Select the User and then select Add Role Group to configure the Role Group. (Be sure that it matches an existing AD group name.) When logging into the IPMI web console, use the following format to log in: username@domain. Should you find yourself with a task too big to be handled manually such as configuring the same but on a miriad of nodes there is some help available. SMCIPMITool is a ut

Companies merge, hosts are inherited and repurposed, administrators come and go and not necessarily leave things in order after themselves. Or what if you forgot the password and the record of it is not recoverable? Where there’s a will, there’s a way. I touched the other day on how ipmitool can be accessed from a CVM CLI but would require authentication details to pass on to the IPMI. Well, the host or rather the hypervisor installed on the host does not have to do so. Hence even when ADMIN account password (or any other account with full privileges) is lost the IPMI is still accessible from the hypervisor CLI and you can still reset the password, set up new user entirely, or set a new password for a user. The process consists of several steps: Log in to the hypervisor on the host (AHV or ESXi). List user records using ipmitool. Take note of the user ID. Set the passwo

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 All I have created a MS server 2016 VM with a view to using it as a desktop , however it does not seem to have away to add anaudio / soundcard device - is there a way to add one in Nutanix?  I have found a way in VMware but not Nutanix. Any ideas? Thanks Eric

Hi Team,I am trying to export cluster info with the below code which I got from the internet (do not remember where I got this). but the below script runs fine and able to export the data required except for Cluster name and its IP address.As per my understanding it is able to export only the content of “NTNXHost” but not the content of “NTNXClusterInfo” and “NTNXVM”$report = @()$NTNXHost = Get-NTNXHost | Select-Object name,hypervisorAddress,clusterUuid,serviceVMId,serviceVMExternalIP,ipmiAddress,serial,blockSerial,blockModel,blockModelName,cpuModel,numCpuCores,numCpuThreads,numCpuSockets,cpuFrequencyInHz,cpuCapacityInHz,memoryCapacityInBytes,hypervisorFullName,hypervisorType$report+=$NTNXHost$NTNXClusterInfo = Get-NTNXClusterInfo | Select-Object name,clusterExternalIPAddress$report+=$NTNXClusterInfo$report += "`r`n"$NTNXVM  = Get-NTNXVM -SearchString "VM is a Nuta

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

Wandering if someone could point me in the right direction as I am not overally familiar with SUSE. I am replicating from ESX to AVH and have installed NGT. The guest fires in AVH but I have no GUI - it errors that there are no drivers for X. Unfortunately it is stuck in my DR segment for which I only have the Nutanix Console access to at the moment, bets I have is:   Just wandering if anyone had any experience with SUSE / AHV and could point me in the right direction? If I run startx from the console I get no screens found:   Any assistance appreciated.

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?

In Nutanix clusters running AHV hypervisors, we can use the LLDP protocol to find more details about the directly connected switches. LLDP needs to be enabled in the switches for the details to be seen in the AHV hosts.

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.
