Cluster creation or initialization is a process of bootstrapping the cluster by configuring the unconfigured nodes,  load some node information into Zeus configuration file and start the services.  Let's break it down.  What is an Unconfigured node? Node which are factory shipped. Node which was removed from an existing cluster. These nodes are typically Pre-installed with CVM/HypervisorN

As of Nutanix Collector release version 3.0 and later, it is now possible to collect statistics for Hyper-V clusters along with AHV and ESX clusters.From the initial home screen, simply select the “Hyper-V” option from the “Run on” drop-down, then enter the IP address or fully-qualified domain name (FQDN) of a Hyper-V host, followed by the username and password of an Windows administrator from the administrator group. Thereafter, simply select the entities from which you would like to collect statistics and click the “Collect” button.Please note that any Hyper-V hosts being connected to should be running PowerShell version 5 or later. Also, as Collector currently only collects configuration data from Hyper-V clusters, the Collector performance graphs may appear as blank following a su

We have a very long domain name and with the current config we are using the UPN (name@company.com) name to login. This is becoming very irritating for me to enter the domain name each time I login. Can we configure a default domain for all the login users to use if the user didn’t mention any domain and of course if we don’t have local user by the same name?

ESXi 7.0 requires a minimum of 4 GB of physical RAM. Provide at least 8 GB of RAM to run virtual machines in typical production environments.4GB only for the HOSTAnd about AHV?What is the minimum memory for AHV only?, without CVMs and VMs

I see that ERA 2.0 has a prerequisite of SQL Server SQLPS PowerShell module. Does anyone know what specific version is required? I ask because when trying to register a single node, I receive the following error:Operation Failed : Unable to import SQLPS module. Please make sure that SQLPS module is available to proceed with Dbserver VM registration.I suspect that the version of SQLPS PowerShell module that we have installed on our SQL servers is too new. 

Hi All, Does anyone know if it’s possible to pass variables into the ‘Custom Script’ / cloud-init section, when creating a VM in AHV via Prism Element?Ideally, I’d like to use the REST API to create (clone) a VM from a template, and pass a ‘Custom Script’ perhaps from an ADSF path, that is able to configure the guest’s Hostname / FQDN based off the VM’s name specified in the REST API call.IPAM and some basic cloud-init config is working, just trying to determine the best way to set the hostname!

We have added Dell Switches to see the Interface information and where our AHV hosts are connected through Network Tab.But, I am able to see Interface only on One Switch for one host, not on others. I see below. Is there anything we are missing.  

Customers can observe cluster issues when they use more than 90 percent of the total available storage on the cluster. This article provides general guidelines on the maximum storage utilization on a cluster. The total available storage capacity on a Nutanix cluster is the sum of all the available storage space across the nodes.Customers should not try to use all the available space in the cluster. Sufficient space should always be available in the cluster in case a failure occurs. For example, when a disk fails in the cluster, the extent groups that were present on that disk have to be copied to other disks to ensure that all the data is at the configured replication factor. If the disk space is unavailable for this activity, then there is a risk of data loss if more failures occur with t

In some scenarios, when you enable the remote support tunnel, it’ll tell you that it has been temporarily enabled but the status will show “disabled”.To troubleshoot, you can start by checking Basic IP connectivity to nsc01.nutanix.net or nsc02.nutanix.net. If that times out, then it is either a DNS resolution problem or a firewall issue.Check the firewall rules of your system to allow outbound connections to nsc.nutanix.com on port 80 or 8443.For more details on troubleshooting, check KB-1044

Hello Team, I’m running a small 3 node cluster, during an AHV upgrade to the latest version one of the servers failed to reboot so AOS started to rebuild trying to restore HA. After several hours rebuilding failed, looking at the logs I saw the message: “not enough space available”. If I’m not mistaken a 3 node cluster can tolerate only one node down, but lets say the two running nodes had enough space, is it possible to restore HA? It basically means that after some time rebuilding, if one of the 2 remaining nodes fails, cluster is still up in a single node mode.Just curious because it looked like AOS tried to rebuild HA despide only 2 nodes were up

Note -  Nutanix highly recommends using Nutanix Move to migrate VMs to AHV. See the Nutanix Move documentation at the Nutanix Support portal. This KB should only be used if Nutanix Move cannot be used or for reference only. For large scale migrations of business critical systems, Nutanix Global Services organization pr

As companies become more security aware, third party security tools are being utilized more heavily than ever before. One such tool is a security scanner which can review open network ports within an environment and report back on certain vulnerabilities (CVEs). This includes the open ports of Nutanix specific components such as the IPMI.While it is important to keep the IPMI/BMC upgraded to the latest version so as to integrate the latest security patches, there are CVEs that will still report as failed by scanners based upon the default IPMI configuration. This is due to the virtual media port (623) and the iKVM port (5900) being opened by default.The virtual media port allows the user to open a remote session to the host console and the iKVM port allows the hosts to query information from the BMC.The specific CVEs affected by these two ports being open can be found in KB

Do you already have many security policies defined within one instance of Flow and, have another instance where you need the same set of policies but do not wish to recreate them? Or, do you wish to simply have a backup of your existing security policies just in case you should ever need to restore them sometime in the future?Flow has the native ability to export (and subsequently import) security policies that have already been defined previously. Policies are exported into a single binary file, which can then be transferred to a different instance of Flow or stored-away for backup purposes.Please also note that, when importing a previously exported binary file, any existing policies which are already defined within a given Flow instance are automatically removed in-favor of the newl

Synopsis: The goal of this workflow is to walk-through troubleshooting VM to VM communication issues in a Nutanix Cluster. Most customers are very vague when they state they have a networking issue. We will go through painting a complete picture of the network topology by asking the right questions and running commands on the Hypervisors.  Initial Triage:Questions to Ask:  What hypervisor is running on the

Hi all.I’ve been trying to figure out how I can execute a PowerShell script inside a guest VM, both Linux and Microsoft, on AHV through the host but can’t find any solid information on the topic.There is a discussion called “Execute Script Inside AHV VM?” but that is only for initial configuration of the VM. I’m looking for a way to execute an arbitrary script on any running VM without having access to the VM through its default network configuration.It’s basically a hosting situation where customer VMs exist within their own isolated environments and I’m responsible for running various scripts for - among other things - joining new servers to AD, installing SQL Server, patching the OS, etc, etc.Looking at this post there seems to be a way to run scripts through NGT but when reading the Nutanix Bible that option seems to be limited to VM creati

Please consider the possibility of incorporating the existing IP scheme in the new infrastructure. If changing the IP address is the only option we can utilize a script to change the CVM IP address. You can use the external IP address reconfiguration script in the following scenarios: Change the IP addresses of the CVMs in the same subnet. Change the IP addresses of the CVMs to a new or different subnet.In this scenario, the external IP address reconfiguration script works successfully if the new subnet is configured with the required switches and the CVMs can communicate with each other in the new subnet.

We have a 15 block HPE environment built with AOS 5.15.2. we need to enable flash mode on a NVMe device (vmdk) which is presented within vSphere but cannot be seen via prism element under the VM vDisks or via ssh shell to cvm’s is this feature not currently supported? any ideas I am struggling to find much on the support portal?still unsure on this how do we pin the NVMe vmdk to the performance tier  cheers

If you have a storage container on the cluster and the name starts with a “#”, you may see this error while trying to upload an image:"Could not access the URL nfs://127.0.0.1/%23ISO_Images/.acropolis/image/106ac31b-6236-4534-a2ae-808c08bb912f: Failed to parse the file size" That happens because the URL cannot have the # in the name and it gets automatically replaced with %23. Therefore, this creates the inconsistency between the container name and the URL.To resolve the issue, rename the container and remove the # from the container name and retry the image upload.Take a look at KB-10117 for more information.Check this guide on

To verify if we have replaced DIMM on correct slot and CPU we can use the following method We can look at hardware.history file which records any replacement for example DIMM,SSD,HDD,NIC being made to that node. This file remains local to each CVM After we replace DIMM we will boot the host up Power on CVM and run following command ncc hardware_info update_hardware_info           This will update the hardware.history file present in ~/config directory and it will recognize any new replacement Open hardw

Hello,i have some questions regarding “Switch stacking”1-) Is it possible to use " 2 stacked switches " as TOR with AHV? there will be a problem if we use this configuration?2-) The best practice is to use 2 Stacked switches or 2 individual switches?We plan to use Active-Backup configuration and conect SFP to Switch1 and the other SFP to Switch2I am not a network specialist so i am not sure if both switches are stacked, and we plug 1 SFP to SW1 and the other SFP to SW2, the active passive configuration will work
