How It works

Raghavan Kollivakkam (Director of Engineering) recently put up a post on our developer blog titled - REST API Versioning – A Misunderstood Soul - It's a good read. Have any comments? reply to this post and lets have a conversation.

I'm starting to explore the foundation API for potential to automate the imaging process of new Nutanix clusters. Do I need to have the Foundation VM running and connect to TCP/8000 on that? Can I leverage Portable Foundation?

We are looking to make a hardware purchase in the near-term and have a question: Is there a necessity to go with SAS versions of SSD's? Or, are SATA versions sufficient? Also, we are weighing the options of the all-flash and hybrid (SSD & HDD) storage models. Please provide your experience with either. Thank you in advance for your response, -Tom

Please help on where are the created snapshots stored in Nutanix

Hi, I am currently working with a customer who is looking into Nutanix and we are planning a POC. They have large VMWARE environment running 6.7. They have some applications that require SR-IOV. If we decide to go to Acropolis, is SR-IOV supported in Acropolis or is there a feature similar to that available natively on Nutanix? Many thanks.

Hello All, I can not list the VMs with the v3 version, I have the same error with the API explorer, I have an error 403, my cluster is in version 5.5.3.1 can you help me?

Hello Experts, I am new to Nutanix world and in middle of acquiring basic knowledge. In Prism console under software upgrade, i can see that there are components like AOS , Foundation and Hypervisor. My understanding is that the Acropolis ( AOS ) software is installed in CVM and CVM is called as Foundation. Hypervisor is either AHV or Vmware or HyperV. Is my understanding is correct ? Please clarrify Thanks Sam.

Hi, Is there a way to see/export the Hostname and IP of the VMs with the API via cURL? Anybody have an example o extract this information? Thanks Regards

Hi Together, How does the nutanix cluster handle failures with following settings: Cluster Redundancy Factor -> 3 Container Replication Factor -> 2 1) How many disks or nodes can fail? 2) Does this settings make sense or should the Container RF always set to 3 when Cluster RF is 3? Thanks for clarification! Kind Regard Steve

Dear All, Currently my Nutanix cluster consist of 3 Nutanix block, 5 node running on AHV 20170830.171 1 block of 3 NX-1065-G5 node 1 block of 1 NX6035-G5 1 block of 1 NX6035-G5 Recently, one of the NX6035-G5 is down due to hardware issue. Somehow, all the VMs hosted on this node not able to auto failover to the others node. Upon checking with Nutanix, we were informed that the failover failed as we don't have sufficient available memory. We were told that AHV will perform the failover for all the fail VMs to one particular node which have sufficient resources to accommodate it; like moving the whole load from the fail node to another node. Previously we are using VMware where it will failover VM by VM to all the available nodes. Anyone encounter similar issue with AHV?

Hi, I am actually doing my end of study internship, My subject is " implementation of hyperconverged infrastructure" I want to know how to migrate VMs from a legacy infrastructure with vmware Vsphere 5.6 to Nutanix hyperconverged infrastructure with VMware vsphere thank you.

Does anyone have a working example?

Please let me know if there is any reason as why VirtIO is shipped separately?

Hi folks, I would like share with us the powershell script that use here in my company, this script do inventory of vms that run in nutanix environment AHV and collect the information like : name,servicevmexternalip,hypervisorFullName,blockModelName,cpuModel,numCpuSockets,numCpuCores, after collect we can export in csv and HTML to send by email Link to script: https://github.com/joaocsjr/powercli/blob/master/ntx-invetory1.ps1 Regards, Joao Castro

Please help: When we have couple of vdisks in Volume Group can we delete that Volume Group? If yes, what happens to the vdisks which are already in that deleted volume group?

While creating the VM, is there a way to change the boot sequence? If no, how does Nutanix boot up the loaded image iso?

If we use the ESXi/Hyper-v as the Hypervisor, does the Satadom will be formatted(Removing AHV) and then install ESXi? What happens to CVM in this case? Any manual operation is required?

I'm having an issue disabling client authentication via REST API. Here is my code: code:$disableauth = @{ value='false'}$disableauth = $disableauth | CovertTo-Jsontry { $r = Invoke-RestMethod -Method Post -Uri https://clusterip:9440/PrismGateway/services/rest/v2.0/authconfig/client_auth -Headers $head -ContentType $content -Body $disableauth } catch { $_.Exception.Message; } When I run this command, it gives me an error of "request aborted: could not create SSL/TLS secure channel". I have a similar call I use to enable authentication, which works without issue.

Please help me with the following: Where do the AOS sit? Is it inside the CVM or on the SATA DOM? Is AHV created when the AOS is installed or vice versa

Hi all. I have read the document about the different failure scenarios. For me it is still not clear, what really happens, if the data resiliency status is still critical and another node fails. In the doc I read this: With two sets of physical disks that are inaccessible, there would be a chance that some VM data extents are missing completely. In our starting time when using Nutanix (version 3.x) I remember our Nutanix partner was telling me, in such a case the cluster stops to make sure data keeps consistent. Do I have some UVMs that are not working any more correctly or is cluster stopping and all UVMs are stopped? Thank you very much. Kind regards, Stefan

Hi, I've been trying to get access to PE Health Status (e.g. Failed, Warning, etc) via CmdLets or REST API with no much luck. Any ideas? Cheers, Manuel

Hi, I am not able to get Data Resiliency status using Rest api version v2.0. I see for v1 it is https://server_ip:9440/PrismGateway/services/rest/v1/cluster/domain_fault_tolerance_status Using v1 as well I am not able to get this metrics value. Please help us in getting Data Resiliency status using Rest api version v2.0. Regards, mallikarjuna

Hi. We have a large grouping of VM's that are not always required to be running and would like to find a way to shutdown these particular VM's on a sunday night. Now anyone know how to find a group of VM's (either via label, project, category etc) and pass a shutdown command. Ideally I would like to do this via PowerShell but I will take anything.

Hi Team, Previously we are using apiversion v1 and getting metrics using /vms https://hostname4:9440/PrismGateway/services/rest/v1/vms/ Now with api version v2 we are not able to get below mentioned metrics hypervisor_cpu_usage_ppm not able to find this with both urls(vms,virtual disks) hypervisor_memory_usage_ppm not found memoryCapacityInBytes not found ipaddresses not found but found requested_ip_address are both same?? controllerVm not found Able to get few metrics using virtual_disks and above mentioned metrics we are not able to get, Are these not available in v2 or modified to anyother url. Please let us know how to get these values using v2 apiversion.

I've written a PoSH script which does the following. Authenticates to Prism Central V3 API Calls /category/query API to get a list of VM uuid's that are members of the PROD category. Write this list of uuid's to a string Connect to the NTNX cluster using Nutanix PowerShell cmdlets. Iterate through the above string and execute Set-NTNXVMPowerState against the uuid's. Steps 1 - 4 work as expected. Step 5 seems to iterate through the list as it should but when I put in the Set-NTNXVMPowerState command to be executed, it throws an access denied error. Once the script gives the error, the powershell connection looks like it locks the account and you cannot execute any commands. If I comment out the foreach loop, and just execute a normal PoSH cmdlet (after the Connect-NTNXCluster) such as Get-NTNXClusterInfo, it works fine. I have tried both my account (which has Prism admin rights) and the Pris
