How It works

Hello,Seeking for advice, I have 3 nodes cluster having problem with node B DIMM is undetected. I’m planning to reseat my DIMM, if I will just manually move the VMs to node A and C then perform a shutdown on node B without entering maintenance mode does the VM will join back to node B?Can please also share a link to a document to refer for the procedure.

I am connecting 5 Nutanix Nodes to two Cisco Nexus 9K cores.The MGMT ports are connected to TOR FEX then 1-10 Gig Fibre to Core1 and 1-10 Gig Fibre to Core2 from each node. All 10 are VPC ports in trunk mode, switchport trunk native vlan # with spanning-tree port type edge trunk.My question is, I found a Nutanix article #000002455 for Cisco Nexus Recommended Pratices and they state you should add to the configuration spanning-tree bpduguaard enable and spanning-tree bpdufilter enable.Cisco says they dont recommend these spanning-tree settings.Who is right?

Hi everyone,If you have 5 blocks with 8 nodes installed in the same rack, will you keep using RF = 2 or 3, or will you use fault tolerance domain to block instead?

I have a Nutanix cluster with 4 hosts and 4 blocks. Is it possible to remove two nodes from Cluster ?

Dear All,I’ve got a question?I am in the process of Moving Windows machines from a VMWare infrastructure to Nutanix.1 of my machines to a USB dongle for an application license.Could you tell me if it is possible to mount a USB dongle in nutanix like in VMWare?Thank you in advance

Hi,A previous post by Jon from Nutanix stated that “Licenses are not tied to support agreements. Am I correct in assuming that support purchased/renewed for NX hardware covers both hardware and software support? Also is it safe to assume that the support level is not impacted by the license level on the node. For example, a node using AOS Pro license will NOT receive a higher level of support than a node using AOS Starter license if they both have production support. My understanding is that the only thing that impacts the support level is the type of support purchased, that is "Production Support vs "Mission Critical Support".   Thanks,--Zip

When looking through the IPMI event logs, you may come across a “General Chassis instruction” message that is asserted. This is event created when the node needs to be opened to conduct a replacement and the top cover is opened as a result.The chassis intrusion feature makes it difficult for a potential intruder to reset the sensor without authorization. Therefore, there is no physical button to reset the sensor on the node. The user has to reset this sensor in the IPMI web GUI, which is authenticated using administrator credentials.To find more information about this feature and instructions to reset the sensor, look at KB 1362 on the Support Portal.

In this Google-ready culture, many users will immediately turn to an internet search engine when seeking for information regarding a specific question or issue involving Prism. However, many users are unaware that Prism maintains an online help system which responds-to and changes depending upon which dashboard is currently being viewed within Prism.For example, a user may be interested in deploying a File Server and may have questions regarding this while reviewing the File Server dashboard within Prism. From that dashboard, simply clicking the global question mark icon from the top menu and selecting the “Help with this page” option will automatically open a new browser tab to the File Server Management section of the Prism Web Console Guide. What’s more, the specific version of the Prism Web Console Guide that is displayed corresponds to the current version of Prism from which it was launched.Further, some of the dialogue boxes within Prism also contain a question mark icon which wi

Hi,First time attempting to install Nutanix. I’m experienced with VMWare, but I wanted to try out Nutanix, mainly as I read it will allow me to create a single-node cluster, using locally attached NVMe disks without the overhead (headache) of vSAN (that doesn’t work as a single-node).Running through the installer, I see I have to specify an AHV (equivalent of ESX?) boot disk and CVM boot disk that requires a disk of at least 200GB. If I understand correctly, CVM is the equivalent of vCentre Server (VCSA).Firstly, can I install this CVM somewhere else?Secondly, I don’t have a separate disk of >=200GB that I want to waste on CVM. I have a 128GB SSD that I would have used for data, but the installer won’t let me and I can’t use it for CVM either because it’s too small. If I can’t farm off the CVM to another device, is there a way to override this limitation? Even fat old VCSA only uses 72GB across its 13 disks. What is in CVM! These are my disks. As you can see, to install CVM on its o

Does anyone knows size of VM’s snapshot file? I am concern about disk space, but I also need to back up. Is there formula for calculate snapshot file size approximately?   

Hi! I've got several questions about the usage of v2 API which I have not been able to solve by myself after looking a little while.on some endpoints, for example, GET /alerts, GET /vms and a few more things are functioning for me as expected, but on other endpoints, such as POST /vms/{uuid}/set_power_state I am receiving the following response:{ "message": "Access is denied", "detailed_message": null, "error_code": { "code": 1100, "help_url": "http://my.nutanix.com" }}any idea what's causing it? I've been searching for detailed information on your error code (such as 1100 listed above) and couldn’t find. Is there any documentation to the error codes that  you can send me a link to?Also, in a few of the API endpoints I couldn’t understand exactly what is the expected query parameter to be sent.2 examples of endpoints I felt I am lacking knowledge what exactly meant to be sentGET /vms filter: Filter criteria - semicolon for AND, comma for OR. where can I find what counts as fi

Switch engineer changed vlan (vlan id). Is it possibly auto update in nutanix arp table? if not, what kind of command require to do? 

Network visualization Is one of those underrated but extremely useful features. Network visualization is a consolidated graphical representation of the network formed by the VMs and hosts in a Nutanix cluster and first-hop switches. Nutanix network visualization allows you to group VMs by power state or by parent hosts, group hosts by parent clusters or select a particular node from the cluster. Choose your layout based on the current needs.   In Nutanix network visualization, every entity is interactive. For example, when you click on a VM you can see detailed information about its vNICs such as MAC address, IP address, VLAN ID, live statistics.   Similarly, switch port will show information about MAC address, MTU size, live statistics.     To enable Network visualization a set of requirements must be met: Configure SNMP v3 or SNMP v2c on TOR switches Enable LLDP or CDP on the first-hop switches. Network connectivity over SNMP port between CVMs and switch management IP addres

Can anyone explain the function of the command “nodetool -h 0 ring” and also the explanation of its output, because I often see nutanix support using this command, i just curious function this command :D

In some cases, you might have to permanently remove a physical node / host from a Nutanix cluster. There are two scenarios in node removal. Permanently Removing an online node Removing an offline / not-responsive node in a 4-node cluster, at least 30% free space must be available to avoid filling any disk beyond 95%. You cannot remove nodes from a 3-node cluster because a minimum of three Zeus nodes are required. Some Points to consider before initiating node removal: Sufficient Disk space available on other nodes in the cluster User Virtual Machine relocation (if required) Any software upgrade should not be running Checklist on verifying cluster health status Data resiliency is “OK” (green) in Prism Run a complete “ncc report” either from prism or CVM cli:                                 ncc health_checks run_all Depending on the size of data, node removal can be lengthy process, which involves relocating data from the node to other healthy nodes in the cluster.
