AHV hosts in cluster running AOS 5.18 or newer may become non-schedulable if bridge configuration across cluster nodes is not consistent. What is a non-schedulable node?A non-schedulable node is used to increase data storage on your Nutanix cluster and does not run any guest VMs on that node.To check if this situation exists on your cluster and to fix the issue, check KB-10217. 

Hi teams, can i create 3 node cluster with 2 different FC SFP+ switch 10gb because my port is limited? between switch i using FC SFP+ 10gb link. i think the first impact is latency between node, please give me suggestion using this topology  

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

Hi there.  I’m trying to plan an upgrade on our nutanix clusters from VMWare 6.5 to either 6.7 or 7.0 and I’m having a bit of a struggle figuring out the compatibility of the different VMWare versions along with our Nutanix clusters. We have two Nutanix clusters, our main site is a 7-node cluster with 5 Gen5 nodes and 2 Gen7 nodes.  Our remote data center is a 6 node cluster with all Gen 6 hardware.Our main site is running AOS 5.10.5 LTS and our remote datacenter was just recently upgraded to 5.15.2 LTS in preparation for the vmware upgrade.  I plan on upgrading our main site to the same AOS version of 5.15.2 LTS.Where I have an issue is that when running the VMWare Assessment Tool (VSAT) I keep seeing notifications on each cluster that certain nodes may not be compatible with VMWare 6.7 or 7.0 because of various devices that “May not be supported” yet say things like “is certified but current driver (ixgbe) is not supported”.  In some cases the same exact nodes in the same cluster wit

Manual license selection allows the customer to select specific licenses available in the customer account and apply the selected licenses to the cluster. This feature can be used when: Mixing license types (e.g., Life-of-Device and Capacity Based Licensing) in a single cluster Selecting term licenses with specific expiration dates Selecting licenses tagged for specific use cases (e.g., owned by a particular organization) Manual license selection is available as an option to license products on Prism Element and Prism Central.  Where is the Manual License selection option?You see it on the portal’s ‘Manage licenses’ page displayed after .csf file from Prism (PC or PE appropriately) is uploaded. When ‘Select License’  is selected on each card, The pop-up has a ‘manually manage licenses’ option.How to access ‘manually manage licenses’ option on licensing workflow on portal:In the support portal navigate to Products--->Licenses--->manage licenses Manage licenses page: Here ‘Choo

Hello All,I have recently deployed Prism Central and I am trying to give team members access via their AD accounts. I have went through the roles and discovered I cannot add new members to the predefined roles; however, if I duplicate the roles I can add AD users and groups to the new roles. This works for me however when I duplicate a role such as the “Super Admin” role I am warned that not all permissions are going to apply to the new role and I would need to create the new role via CLI to get these permissions. Ok fine that makes some sense. But where is the documentation on how to do that? Can someone point me to the documentation to perform these role creation tasks via CLI?Thanks, Scott

Hi all,Running AOS 5.10.5, i have changed my cluster from RF2 to RF3, including my main container and the “SelfServiceContainer”,however a week after the change I’m still seeing this error regarding extent groups,I believe that this is due to NutanixManagementShare still being RF2 (with no ability to change it, since its a systemmanaged container), or is there some other reason?

Nutanix provides a suite of utilities for cluster maintenance, including tools and scripts that help you use CVM and Prism resources more efficiently.Latest Version of Cluster Maintenance Utilities is CMU 2.0.3Procedural Notes:Update CMU with the Life Cycle Manager, starting with LCM version 2.3.4. Nutanix supports CMU with AOS 5.10 and later, and with both Prism Central and Prism Element.New Features:Beginning of update Support for CMU Scavenger tool for Cluster Cleanup (Scavenger is not a cluster-level service. It operates per VM)CMU 2.0.3 Release Notes

In VMware vCenter, when a new cluster created, the default  HA configuration is disabled: When opening the HA configuration for this cluster (Select cluster in inventory -> "Configure" tab -> vSphere Availability section -> "Edit" button for vSphere HA) we can see that HA is disabled and the response for "Datastore with PDL" and "Datastore with APD" is pre-defined as "Power off and restart VMs".  While this new cluster is still empty, if vShere HA is turned on from this configuration window, it unlocksconfiguration sections for PDL/APD response: If the response under "Datastore with APD" was not changed to "Disabled" before adding host(s) to the cluster then, later when freshly imaged ESXi host(s) (with Misc.APDhandlingEnable = 0 set by foundation process) are added to cluster, the APD response configuration section is locked and cannot be changed to "Disabled" according our recommendations for standalone clusters. As a result, attempting to enable HA on this cluster fails wit

Nutanix presents us with many management interfaces like HTML5(Prism), REST API, acli and ncli for managing and troubleshooting and maintaining work infrastructure.  We will look into how to access the Nutanix Command line Interface and what the capabilities and purpose of acli and ncli command-lets areaCLI: Acropolis Command Line Interface  Utility to create, modify and manage VMs in AHV. Provides extra abilities(commands) to manage AHV host networking, manual snapshot etc Cannot manage Nutanix Cluster and so we have ncli nCLI:  Nutanix Command Line Interface Utility to manage the entire Nutanix cluster operations. Ncli is more extensive and complex command set To access the CLI, You can install it on your local machine Check out how to install ncli on your local machine here. From any Controller VM SSH to any CVM as a nutanix user and type ncli and hit return to enter the ncli command shell and will be the same process for acli.Once inside the shell, you can view the list o

What is vNUMA?vNUMA (virtual non-uniform memory access) is a memory-access optimization method for VMware virtual machines (VMs) that helps prevent memory-bandwidth bottlenecks.The primary purpose of vNUMA is to give large virtual machines (or wide VMs) the best possible performance. vNUMA helps the wide VMs create multiple vNUMA nodes. Each vNUMA node has virtual CPUs and virtual RAM. Pinning a vNUMA node to a physical NUMA node ensures that virtual CPUs accessing virtual memory can get the expected NUMA behaviorBefore enabling vNUMA on Virtual Machines, see AHV Best Practices Guide.To enable vNUMA on your Virtual Machines, check this guide.

Many users are unaware that there are additional (beyond what is displayed through the Prism web user-interface) configurable security-related options which can be used to increase the security settings of the controller VMs (CVMs) themselves. These options are modified using the Nutanix Command Line Interface (nCLI) of the CVMs and include some of the following items: Enablement of an Advanced Intrusion Detection Environment (AIDE) Enforcement of a strong password policy Enablement of a defense knowledge consent banner Restriction to allow only SNMP version 3 You can find more information regarding these options, including the procedures to enable/disable them, within the Hardening Controller VM section of the AOS Security Guide. Also to note, there are similar options available for Acropolis Hypervisor (AHV) hosts which are configured using the same procedures. You can find more information regarding those options within the Hardening AHV section of this same guide.

Hi there!I’ve installed NutanixCE (twice!) on my existing hardware (custom SuperMicro servers, not Nutanix hardware, though they meet the required specs).  We found it useful, and decided to spring for Ultimate Licenses for the non-Community Edition.So I’ve got those licenses, but now I’m having a heck of a time figuring out what to download and install!  For CE, there was a nice procedure to create an install image on a thumb drive, but I’m not seeing the same thing for non-CE.Can anyone point me to documentation that spells out what needs to be downloaded and how to install it?I’ve already found the AHV admin guide, but that doesn't have installation instructions.I’ve found the “Field Installation Guide - Foundation 4.5.x”, but the “https://portal.nutanix.com/#/page/docs/details?targetId=Field-Installation-Guide-v4_5:Prepare%20Bare-Metal%20Nodes%20for%20Imaging” section seems impossibly complicated; do I really need to install and configure a VM on virtual box on a laptop in order to

Here are simple steps in order to license the newly added node/nodes to the existing cluster:1. Generate a new cluster summary file from Prism element (cluster)2. Upload this file in the support portal under “manage licenses”.{Menu-->Licenses-->manage licenses}3. Next click on “manually manage licenses” option in blue.4. You will see your previously used up licenses , now you need to select licenses for the new node (click on dropdowns and put a check mark)5. Once you have selected all licenses you will get an option “save” and then “Next” on the bottom right.6. Next page will show you list of licenses which would be consumed, click on “confirm”.7. License file is generated , apply this file to the cluster. All nodes should be licensed now.  

https://next.nutanix.com/how-it-works-22/network-segmentation-basics-38414It seems the network segmentation 2.1 doesn’t support the isolation physically between the backplane and management. So, it tries to isolate logically following this procedure.ISOLATING THE BACKPLANE TRAFFIC LOGICALLY ON AN EXISTING CLUSTER (VLAN-BASED SEGMENTATION ONLY)https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v5_15:wc-network-segment-on-existing-cluster-wc-t.htmlAOS5.15.1 / ESXi 6.7u3 Standard vSwitch, vSwitch0 Port Gourp: Backplane Network, CVM Backplane Network (for CVM)it doesn’t recognize any port groups.The procedure doesn’t mention about the vSwitch0 or port group condition. Is there any information of this?Thx,

Are there plans to validate a version of VMware’s ESXi hypervisor that addresses recent vulnerabilities outlined here; https://www.vmware.com/security/advisories/VMSA-2020-0023.html The proposed version to address this threat is ESXi670-202010401-SG for existing 6.5 hosts or ESXi675-202010401-SG for existing 6.7 hosts. It appears that the latest json version for download from My Nutanix is 6.7.0 U3 - which is slightly older than the version being proposed to resolve the vulnerability. Thanks!

Hi!While reading the documentation for storage QoS the following is mentioned as a limitation:Storage QoS is not supported for Metro Availability, synchronous replication, and AFS virtual machines.What will the actual result be if I apply storage QoS to a VM that I also replicate synchronously? Can I even do this? Or vice versa, what happens if I start replication of a VM with storage QoS?In what way does storage QoS conflict with Metro functionality?Thanks.

We have a couple of 2 node cluster with a Witness VM on a separate host but I can not seem to find any documentation on how to enable SNMP on it.Using the “ncli snmp add-user” command that works for normal CVM’s just throw me the error:“Error: Cannot connect to Prism Gateway”Any ideas?

Hi,Do PD snapshots eventually all expire on my DR site if I lose the primary site (no communication between)?For instance I have a PD with 5 hourly replication snapshots retained locally and remotely. If I lose the primary site but can’t get to the DR site for say 6 hours, will I still be able to recover the PD?Thanks!

Is there a way using PowerShell to assign a large list of VMs to run from only specific hosts within an AHV cluster?  Basically is there a way to assign host affinity to a list of VMs?  I found commands for anti-affinity using the CLI but could not find anything related to setting affinity.  

Did partners lose the ability to manually configure nodes?  I need to see available procs for a model and all of a sudden I don’t see a way to look at any manual configuration options.  This isn’t good.
