When installing ce-2020.09.16.iso, I get an error about: hdparmStandardError Failed Command [hdparm -z /dev/sda] with reason [BLKRRPART Device or resource busy]My config is as follows: - Intel PC (Optiplex 9020) - USB disk with the .iso to boot from - A single Harddisk to do the installation onThis is reproducable on an Intel-NUC, exact the same issue..Now, I add an additional Harddisk (two HDs and one USB). Note that both HD’s are not carrying any nutanix data, format or whatsoever. After the boot I get a different error:Phoenix: ISO is already mountedFATAL: Couldn’t find a hypervisor and an AOS installed, please package phoenix with a hypervisor and a AOS. Please refer to Nutanix support portal for more information about this.My questions:Why do I get an hdparm error in the first place. When adding a disk, apparently to get around the hdparm error, I suppose that the ce-2020.09.16.iso supposed to provide me the hypervisor and all this.Not sure if the hdparm error is related. Furt
Many users try to periodically execute the NCC health checks as a good offensive tactic against any issues that might appear within their cluster, which is a great idea! However, rather than writing that down as a reminder somewhere or simply trying to remember to do so, many do not realize that this task can be scheduled right from within Prism.The task can be configured to execute as per the following schedules: Every 4 hours Every Day Every Week When choosing the every day or week options, you are also presented options to configure the execution according to a specific time of the day and specific days of the week respectively.What happens with the results when the scheduled NCC checks are executed? An email is sent to the email recipients configured within the Alert Email Configuration settings of the cluster.For more information, including the specific procedures for configuring this feature, please refer to the Scheduling and Automatically Emailing NCC Results section of the
Hello All, currently i am working on this project that uses nutanix 4 nodes and commvault as a backup and recovery solution and also have tape disks for archiving, now i have already installed commvault commserv on nutanix as a virtual machine but the trouble i am having is how to configure the storage for commvault and how to integrate the tape library to the nutanix node so that commvault can access it and made archive to it. please any advice and best practice you know will be very help full i am new to this kind of configuration.
Hello All,I have successfully installed Prism Central and it has been working well. I have configured a “view” under the focus button in the vm’s menu; however, this setting will not stay once I log out and back in. Currently the process is once I log back in I need to click on focus and pick my view. Is there a way to make that my default view? Maybe tie the view to my user account? I have included and image below to help. Thanks,Scott

I have a setup with two subnets in the (same) native vLAN. The first subnet is (kind of) forced on me by Unifi (router, switch, APs in in the native vLAN) and I created the second subnet for Nutanix (recommendation ist only Nutanix devices/VMs in the same subnet). Now I need a router or routes configuration in the Nutanix subnet to get access to the other subnet and the internet. What do you suggest to achieve this in a simple way or what is the recommended way of doing that?
Hi All,Does anyone know the command ovs-appctl lacp/show br0-up it show:slave: eth3: current attached port_id: 2 port_priority: 65535 may_enable: true actor sys_id: 0c:c4:7a:1e:3e:6e actor sys_priority: 65534 actor port_id: 2 actor port_priority: 65535 actor key: 1 actor state: “activity timeout aggregation synchronized collecting distributing”I have set lact rate fast on both nexus switch and nutanix,but what it means “activity timeout aggregation synchronized collecting distributing”“activity timeout aggregation synchronized collecting distributing” Will it affect the quality of the network ? Thank you
Hello, All.Good day!! I have an issue and need your help and advice. 1. using 10 nodes, but I want to configure 2 clusters with 5 nodes each. (Composed of RF3) 2. In a cluster consisting of 10 nodes, the removal of 5 nodes was successfully completed. 3. Then, cluster creation was done manually for 5 nodes that had been removed.cluster -s 22.214.171.124,126.96.36.199,188.8.131.52,184.108.40.206,220.127.116.11 --skip_discovery create --redundancy_factor=3 4.

There are times when working with your environment that one of the Linux guest servers will go unresponsive. Nutanix Support may ask for crash dump files from the Linux VM to further analyze the cause.One such method is to use “sysrq”. This utility found on the Linux Guest OS allows access to several essential kernel commands and allow Nutanix Support to take a more holistic approach in trying to find a root cause.NOTE: If the VM is hung/inaccessible and "sysrq" has not already been activated, you may not be able to generate a core dump with the following method. You can configure the "sysrq" when VM is up and running and wait for the future occurrence.For more information on how to activate this feature, take a look at the KB 9066 on the Support Portal

Hello everyone!I‘m running the CE on an SuperMicro Server. 1 SSD, 2 HDD 4TB. Everything was working like a charm.last week one HDD was taken offline due to smart…Hades.out quoted „Disk model HGST HDN724040AL not found in hcl.json. Running the default short test“After replacing the broken Harddrive and booting the Cum is not responding anymore.ssh email@example.com causes a „no route to host“any Ideas are welcome!Thanks Mike
Executive SummaryThis document makes recommendations for designing, optimizing, and scaling Microsoft SQL Server deployments on the Nutanix enterprise cloud. Historically, it has been a challenge to virtualize SQL Server because of the high cost of traditional virtualization stacks and the impact that a SAN-based architecture can have on performance. Businesses and their IT departments have constantly fought to balance cost, operational simplicity, and consistent predictable performance.Nutanix removes many of these challenges and makes virtualizing a business-critical application such as SQL Server much easier. The Nutanix distributed storage fabric is a software-defined solution that provides all the features one typically expects in an enterprise SAN, without a SAN’s physical limitations and bottlenecks. SQL Server particularly benefits from the following storage features: Localized I/O and the use of flash for index and key database files to lower operation latency. A highly dist
I have a 3 node AHV cluster that uses 2x200GB SSD + 2x6GB HDD disks for each node. Would it be possible to add nodes to this cluster that uses 2x480GB SSD + 2x6GB HDD disks?Option is to first upgrade the 200GB SSD disks to 480GB to align all nodes to the same hardware. Maybe there is some gain in that?
Many users are unaware that network traffic can be segmented (or separated) within a Nutanix cluster for various functions or purposes. For example, backplane traffic can be separated from Management-Plane Traffic so as to allow for even greater available bandwidth for the backplane traffic. Further, as another example, DMZ related traffic could be isolated to specific host uplinks. The four primary means of network segmentation are the following:Isolating Backplane Traffic by using VLANs (Logical Segmentation) Isolating Backplane Traffic Physically (Physical Segmentation) Isolating Service-Specific Traffic Isolating Stargate-to-Stargate traffic over RDMATo note, certain means of segmentation are limited to certain hypervisor versions. For example, the segmentation of management and backplane traffic is supported across the AHV, ESX and Hyper-V (Hyper-V offering logical segmentation only) hypervisors, while service-specific segmentation is supported only by the AHV and ESX hypervisors.
Nutanix VirtIO includes device drivers specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance. This concept is very similar to VMware Tools for ESXi environments.The VirtIO bundles various drivers including:Balloon Driver Ethernet Adapter RNG Device SCSI pass-through controller Serial Driver SCSI ControllerThe VirtIO package is found on the Support Portal under AHV (please select “VirtIO” from the corresponding drop-down menu).To note, the device driver versions contained within the various available Nutanix VirtIO packages may be the same if there have been no updates for the drivers between the package releases. To correlate the driver versions associated with each VirtIO package release, please reference KB 5491 in the Support Portal.Further to note, beginning with VirtIO package release version 1.1.6 all driver versions match the VirtIO package version.
Looking at the site below, I understand that ESXi 7.0 is supported. But I'm not sure if vCenter 7.0 is supported.https://portal.nutanix.com/page/documents/compatibility-matrixIs it a problem to use vCenter 7.0 ?Also, where can I find out which vCenter versions are supported?
Nutanix AHV uses Open vSwitch(OVS) to connect to the CVM, the hypervisor and the user VMs to each other and to the physical network on each node. The CVM manages the OVS inside the AHV host. Since the OVS is an open source software switch that behaves like a layer-2 learning switch, it maintains a MAC address table. Each AHV server maintains an OVS instance, managed as a single logical switch through Prism. Bonds:When multiple uplinks are used they are added to a bond acting as a single logical interface, to which the bridge is connected. Open vSwitch (OVS) does not support bonds with single uplink and as workaround we directly connect bridge to single uplink.WARNING:Avoid the use of a single uplink configuration and do not attempt to modify a single uplink configuration using manage_ovs if the version of AOS is 5.10.x prior to 5.10.4. Warning:Updating uplinks can cause short network disconnect. It is strongly recommended performing network changes on a single node at the time after ma
I am trying to install ubuntu server 20.04 LTS but everytime I reach the point where to set the profile (name, username and password etc...), I get an error “Sorry, there was a problem completing the installation”…I have downloaded the ISO file from Ubuntu, and my VM settings are:CPU = 1Core or. CPU = 2Memory = 4Cd-rom = ide.0Disk = scsi.0 and 100 GiB Please advice how I can fix this, and install my Ubuntu server 20.04 LTS
