Deployment Success

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 a

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 knowledg

02/09/2021 Update: 3.10.1 has been released and contains the fix for this problemAn attempt to add a cluster with NVMe drives in the X-Ray 3.10.0 fails immediately.While checking the log on the X-Ray VM the following can be observed in the xray.log:ERROR Error occurred while performing final discovery - Invalid value for `type` (SSD-PCIe), must be one of ['HDD', 'SSD', 'Unknown'] That issue is specific to the version 3.10.0 of X-Ray and affects only the clusters with NVMe drives. It is a software bug that is going to be fixed in the upcoming release 3.10.1.The workaround is currently to use the earlier versions. X-Ray 3.8 is validated to work correctly.Earlier versions of X-Ray can be downloaded from the following page: http

Flash Mode is a great feature ensuring that VM workloads remain within the flash (SSD) tier of storage. Once flash mode is enabled for a virtual machine, all of the disks associated with that VM (including any future created disks) automatically get added to the flash tier.However, sometimes having so many disks within the flash tier can cause performance degradation for other VMs that are not configured for flash mode (but could benefit from using the flash tier of storage) or can cause the available flash tier space to be consumed too quickly. Further, it is sometimes not desirable to have all of the disks associated with a virtual machine contained within the flash tier.Accordingly and, though not available as a Prism Web user-interface (UI) modifiable option, individual VM disks c

When I try to run the Nutanix foundation applet, Java tells me that the file does not meet high or very high security requirements and that it is missing a certificate. I can’t add it to the site exception list because the file: protocol is not secure. Some guidance would be helpful. 

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.

I am facing an issue with the sizer while generating a budgetary quote.  Help please! 

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

Hi I deploy a 3 nodes cluster with ESXi 7.0 as the hypervisor successfully on AOS 5.15.3.But when I run the diagnostic.py to check the  cluster performance. It always failed to boot the diagnostic VM. I tried 3 times and all is same. from the log, seems the CVM cannot reache the diagnostic VM when check the boot status.I login to vCenter and check that there is no IP address for this VM in the summary page. And I can login the diagnostic VM from the VM console, I can check the ip address which is 192.168.5.253, but I cannot ping 192.168.5.254 and 192.168.5.1. also cannot ping 192.168.5.253 from CVM.From this information, I think the CVM cannot reache the diagnostic VM and timeout, so the diagnostic.py will fail after timeout. Is there any idear for this test? I can run thie script successfully in ESXi 6.7.

I have 20 clusters under management of our Prism Central and would like to know the versions of NCC installed in each. Is there a way to singularly collect this info across all PE clusters? Perhaps in nCLI even?

So guys I’ve got a flexlm license server running Windows Server 2019 that I am trying to use Move to migrate into my AHV cluster.  I tried migrating it once and it blew up the license server since I guess it builds a unique machine ID using a disk and perhaps CPU ID. Any idea on how to clone this in Move so when it comes across FlexLM and other license daemons are none the wiser?

This article contains IPMI commands for checking and setting interfaces to dedicated or shared mode. For example, after a BMC upgrade, the IPMI might not be accessible. So, you need to verify and change the interfaces to dedicated or shared mode. Note: To run ipmitool commands on an ESXI host, prefix all commands with a forward slash (/). Note: To run ipmitool commands from a remote system such as the CVM (Controller VM), add the "-I lanplus", "-H <IPMI IP>", "

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 Ru

Hi,I am implementing a Nutanix Cluster with Lenovo HX5520, when I register the Prism in vCenter the process appears as completed but I cannot create virtual machines by Prism Element and when running the NCC I return communication errors with the vCenter is not stabilized. I did the communication test of the CVMs with the vCenter on ports 80 and 443 and the connection worked successfully.  when checking by cli I see that the connection is ok, but it does not provide me with the settings of vcenter follows the difference from another implementation

Prism Central includes machine-learning capabilities that analyze resource usage over time and provide tools to monitor resource consumption, identify abnormal behavior, and guide resource planning. These tools include VM "right sizing" where VMs are analyzed and those that exhibit inefficient profiles are identified. Anomaly detection to record when performance or resource usage is outside an expected range based on learned VM baseline behavior. "Smart" alerts that trigger when specified anomalies are recorded. Reports that summarize cluster efficiency. VM Right Sizing
