NutanixManagementShare change RF2 to RF3

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?

Enabling HA on vSphere 7.0 cluster fails to enable VMCP

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

Enabling vNUMA on your AHV cluster

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.

Additional Security Options for Controller VMs

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.

Installation basics

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

License a cluster after adding node

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.

VMware hypervisor download

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!

What are the actual limitations of storage QoS?

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.

Does my last good PD snapshot expire if I lose the primary site?

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!

Apply host affinity to list of VMs

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.

Hi.I’ve been trying to find out if I can use X-Ray to test other platforms (VMware and Hyper-V) or if I need to export the test (the “Four corners” in my case) and then use Curie to test the other platforms.There isn’t a lot of information on X-Ray and other platforms to be found though.Thanks.

Disk space taken up by every VM, and all VMs in total, in the Nutanix AHV cluster

Nutanix customers using AHV as their Hypervisor often run into disk space issues on their cluster and need to evaluate how much disk space is being consumed by each entity.  And one of the more important factors that needs to be considered is how much space is being taken up by each VM.  There needs to be an easy way of running one single command and get a listing of the space consumed by each VM, so that at one glance you can figure out which are the VMs that can be removed from the cluster right away in order to get some space reclamation.  As a bonus I have also included the command string that will add up all these numbers and give you the grand total of how much disk space has been consumed by all these VMs put together.I have come up with the following string manipulation to be able to get those numbers:nutanix@CVM:$ for Q in `acli vm.list | awk '{print $1}'`;do echo -n "$Q "; acli vm.get "$Q" | grep vmdisk_size | awk '{sum+=$2} END {print sum}' | awk '{ byte =$1 /1024/1024/10

Prism Network view anomaly?

Hi All I have something odd in my Network view in Prism - I have 3 switches ( 1 switch is a 2 switch stack) but the view shows 5 switches, 2 classified as None. The None entries have the ip addresses of one of the single recognised switches and the stack which is already identified. The other odd thing is that the Nones have ports that I would expect to see in the identified switches. Can anyone tell me how to correct this?

NIC Usage on Nutanix Servers

Hi, Im planning to add 2 more blocks NX-3060-G6 with 2 nodes on each block. Currently i have 2 Block Nutanix NX-3060-G6 with 2 Nodes on each block.Current topology is 2 Block nutanix connected to Cisco 2960X with all eth interfaces connected to it. My question is, In NX-3060-G6 there are 3 Ethernet interfaces, 1 for MGMT (IPMI) and there are other 2 eth interfaces and 2 SFP+. For networking purpose,Do we need to use those 2 eth interfaces from each node in order to work? Or do we need to use only 1 eth interface only on each node? We’re adding 1 more switch Juniper EX4600, so if we need to use those 2 eth interfaces, can we separate them? 1 Eth interface to Cisco 2960X and the other goes to EX4600? Can i have different VLAN on each interfaces (exclude MGMT) that i connect to switch?Sorry if my question isn’t clear enough. But i hope you do understand it. Thank you.NX-3060-G6Networking Topology (Just for Eth Interfaces)
