Nutanix Cloud Infrastructure

Good afternoon, all!I’m setting up a new PKI infrastructure in a Nutanix cluster and I want to shut down the root CA for safekeeping. Is there a way to add some safeguards so that the VM can’t be started inadvertently?

I know there’s another topic like this but, it is 3 years old. Is there an easy way to put a single ESX host into maintenance mode?Not to compare products but with Cisco Hyperflex, you right-click on the host and there’s a “Hyperflex maintenance mode” option.  This does what needs to be done to the CV without having to SSH into anything.I was just wondering if the process has improved in 3 years.

Hi,I cannot expand the cluster when Pre expand-cluster tests were failed and error message was "Failure in pre expand-clustrer tests.Errors:Failed to get vlan tag of node:XXXXX" on Prism Element.CVM and HyperVisor Network use Tagged VLAN and PortChannel in L2 switch ports.Ping to HyperVisor’sManagement IP from other NW segment is OK.Of course, CVM and HyperVisor’sManagement IP are same segment.Should  I do any other? As below, each of versions.・DELL XC640・AOS：5.10.6・ESXi：6.7 Update 2 (Build 13006603)

Hi, We have deployed couple of guest VMs on Windows 2019 Standard Edition OS on our 6 node cluster. Both the guests are configured with 1 VCPU with 2 cores along with 16 & 32 memory respectively. We have procured standard paper license of the OS. The hypervisors are running on AHV version 20170830.337 & AOS - 5.10.8.1 LTS. Is there any specific licensing model for Windows Server OS to run on AHV? How are the Windows licenses determined? Kindly help.

Hi, I’m new on the Data protection feature. I’ve done the a test VM migration to another nutanix cluster. The thing is after the migration, the VM on the source will be destroyed. I’m planning to use the Data protection to migrate the VM from the source cluster to the target cluster. I would need to failback the VM to the source VM. Am I able to restore the VM on the source site? 

Hi All,Does anyone know that veeam can directly add prism central(AHV) for backup?

We are currently evaluating Nutanix and also HYCU for backup. So far HYCU looks really good running on my CE lab server but there is one issue that they cannot answer to. For file restores on older recovery points (past the "Fast Restore" point), HYCU must copy the entire VM from the storage target and mount it to even start the search for a file. While for small VM's this my not be a big deal, larger VM's would cause a wait time based on your network connection to the storage target. For anyone using HYCU is this a concern to you? I'm very interested in hearing real world feed back here. Thanks!

Hi Everyone,I want to know what nutanix version can do replication or leap recovery plan with volume group (iscsi)? I currently use the CE version for testing ,my Nutanix CE and PC version are NUTANIX 20190916.276.I'm testing the iSCSI space of volume group mounted on Windows Server,then execute the plan of leap failure. However, after my windows server fails to DR, there is no iSCSI space on the windows server, and I do not see that the volume group is sync to DR.Is there a problem with my configuration, or is the CE version not supported at present?Has anyone ever done this test?Thanks.

Hi! have a Project in Prism Central that's acting wierd.When i try to update the Project trough GUI i get this error message:Edit conflict: please retry change.Notification { "api_version": "3.1", "code": 409, "kind": "project_internal", "message_list": [ { "message": "Edit conflict: please retry change.", "reason": "CONCURRENT_REQUESTS_NOT_ALLOWED" } ], "state": "ERROR" }So i connect with SSH to a PC CVM, and try to delete the project trough nuclei,<nuclei> project.delete Project \Name confirm=trueConfirm deletion of project? (yes/no) yes{ "message":{ "kind": "project","code": 409,"message_list":[ { "message": "Edit conflict: please retry change.", "reason": "CONCURRENT_REQUESTS_NOT_ALLOWED" } ],"state": "ERROR", "api_version": "3.1" } }It is only the specific project that has this problem, other projects works just fine. I have searched KBs but cant find anything. The ncc health_checks run_all are not showing up anything suspicious.  I have also opened a case on this error!

Nutanix offers a variety of DR solutions. The flowchart provides a detailed representation of disaster recovery solutions.  Leap with two Prism Centrals: Asynchronous replication: it enables you to protect your data with an RPO of 1 hour or beyond.The policy creates a recovery point of the VMs in every 1 hour (or in the hourly time interval that you specify in the RPO) and replicates it to the recovery site NearSync replication: It enables you to protect your data with an RPO of as low as 1 minute.The policy creates a recovery point of the VMs in minutes (1–15 minutes) and replicates it to the recovery site. You can configure disaster recovery with NearSync replication between two AHV or ESXi clusters at the same or different on-prem sites Synchronous replication: It enables you to protect your data with a zero recovery point objective (0 RPO).You can configure a protection policy with Synchronous replication by defining the VMs or VM categories that replicate all the writes on the pro

Why a Grizzly bear? Why not? Awhile ago I created a video showing how you could easily save lots of money by saving dollars on the EC2 costs by using hibernate. Nutanix Clusters is the only on-prem vendor offering this  for customers that want to lift and shift to the public cloud or use the public cloud for DR. I want to share the code snippet and how to create an API user in the Clusters portal.You can first get familiar with hibernate here:  To create an API user to make the call:Go to the Clusters portal  Under Organization go to usersGo to the user optionCreate an API userAdd an API user   You can limit the scope of the user to a single cluster. Once you have a API user you can use the below script to make an API call or add a script to a VM.#!/usr/local/bin/pythonimport hashlibimport hmacimport timeimport requestsimport base64# Client credentials#client_id from the user from the clusters portalclient_id = "*********.img.cloud-internal.nutanix.com" #client_secret password from the

Hi , Could you advice me  ?Now, Hypervisor and CVM is NOT syncronized from NTP Server.I use CloudConnect everyday , but that was failed.Is CloudConnect faiure reason relevent to NTP Server unsyncronization? TestConnect is OK from Onpresmiss Cluster to AWS.I read this;https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_17:wc-cloud-connect-wc-c.htmlSincerely, 

Just curious how other users running AHV plan their ad disaster recovery?  AHV does not support VM-Generation ID so it looks like the most straight forward method not including additional software would be to use the builtin server backup to backup and restore at least the server with the fsmo role.  I wonder what happens in a protection domain scenario especially if there are multiple servers.  Seems like there could be usn rollbacks issues.  Any input on how others are doing it would be appreciated since the documentation seems to be scarce for AHV.

Hi, I am always taken care. I use CloudConnect by VPN connection to AWS and enable NW compression.Everyday repeat that.Since 1 year ago, All PDs are failed. below the message on Prism ;---Replication was skipped for protection domain XXXX of snapshot (X,X,X) to remote site XXX. Replication was skipped as a newer snapshot was available.---I executed cli on CVM, replication statuses are “Sending” .---$ncli pd list-replication-status Replication Operation     : Sending And I did “Test Connection” on Prism was “OK”. What do you think this reason? Sincerely,

Hi,I am always taken care.I'll upgrade Hyper-V 2012R2 to 2016 on XC630 so I have some questions.・metadata(json) download from Nutanix Portal. Can I do that Hypervisor ISO file there ?・What difference are metadata(json)  each ? ・Use Hypervisor ISO file of Evaluation version, is it OK?・ISO's language adapt any languages? or English only? Sincerely,

Hi,I use vSphere6.0 U3 on NX series and set AsyncDR replication to AWS.Some protection domain’s AsyncDR are errorred after VCSA has broken and re-deploy.Are AsyncDR and vCenter  depend on each ?Sincerely,

Setup4 host cluster Every host has: 1 SDD, 1 HDDProblem1 HDD died, CVM doesn’t start: "virsh start" shows: "Failed to start domain" and "Cannot access storage file". HDD is already replaced. QuestionHow do I recreate the CVM as part of the existing cluster?

Hi, I’m tryning to wrap my head arout the differences between Snapshot and recovery point on a functional perspective. My target is to take vmware like snapshot of my vm. For that i saw 2 possibilities :the recovery point, which are managed by PC and allow for easy replication The snapshot which, correct me of i’m wrong) can only be created in PC My issue is that the recvery point cannot be restored “in place”, I mean in the vm object itself, but only by creating a clone of the vm, this create a extra administrative burden if i have to restore a vm from a recent recovery point as i have to :restore/clone the recovery point into a new VM delete the old one update the clone with the previous name, categories, etc ….In addition the newly restored/cloned vm has lost all the previous recovery point However the snapshot can be restored in place, but they are not managed by PC and replicated to the backup cluster … TL;DR ; Is there a way to either create a snapshot via PC or restore in place

When performing a restoration of a VM with a volume group on a different cluster, changes are made to the guest OS in order to connect to the restored volume group.Since the primary site’s data services IP address will no longer be valid, the guest OS will connect to the volume groups using the secondary site’s data services IP address. Also, all other SCSI target IP addresses on the guest OS will be removed.Another change that occurs is the IQN of the VM. When the volume group is restored, the IQN is updated with the timestamp of when the volume group was recovered. This allows for multiple restorations of the volume group if necessary. Therefore, the IQN needs to be changed in the guest OS iSCSI configuration as well. The Nutanix Guest Tools (NGT) CD is mounted on the VM to facilitate this iSCSI configuration change so that no manual changes are required.More information about the above restoration process can be found in the Support Portal here.

Hi,Our 3rd party backup software does a poor job of cleaning up vdisks off of a proxy after it does its backups.  Many times, it will leave the vdisk from a snapshot mounted to its proxy server and not delete it.  This is a known issue that has been brought up with the vendor (Quest NetVault).  Our question is, what is the easy way to see what disks are owned by the proxy VM and what disks are owned by a snapshot image?  We want to be sure we don’t remove a disk that is owned by the proxy server.Thanks,

i have two quetion for our scenario : we have to AHV clusters production and  DR.in our scenario we need to stop the main be active after powered on when resolve the issue becouse if the main server goes down the DR will be active and after resolve the issue the two cluster will be active active?Q2: How to stop auto power on for VMs on AHV ?that means when the main site be on after solve the issue I do not need the VM powered on automaticlly.. I need to power it manually.

Hello, I am an engineer with a security software vendor. We have a mutual customer that seems be experiencing system hangs on their vms in use on their Nutanix Acropolis platform. Admittedly I am not very familar with Nutanix as I mostly work with Vmware. These hangs are reportedly occurring after they upgraded our security product. Vmware has a process where we can create snapshot files and convert them into a memory dump file. This is helpful for our troubleshooting effort when normally you cannot take any action within the vm image to force a dump. I am trying to find out if the Nutanix Acropolis infrastraucture has any comparable capability. I will be suggesting that our mutual customer reach out to you as well, but am trying to inverstigate capability in parallel. Your assistance and advisement is welcome. David Alexander

We’re standing up some docker-based Nvidia GPU compute workloads for the rapids.ai ecosystem for replacing/accelerating Spark & friends. However, we’re lost in Nutanix GPU virtualization docs, so curious if folks have ideas on the pieces for nutanix to work here. Right now, we’re thinking P100/V100 GPU → ahv / esxi → rhel 8.x → docker, and as an optional reach target, see if we can guest multiple host OS’s to share the same GPU(s). We’ve successfully done GPU → Ubuntu+RHEL → docker, but without ahv/esxi in the mix.  Most ahv+esxi gpu articles seem more about VDI than compute, so we’re uncertain. Experiences? Ideas? Tips?

We have the following senario at one of our customersIn the core there are 4 VSP8400 connected in a square. Two of the devices are in a Geo Redundant Datacenter.Between the links is an Extreme L2 SPBm fabric.Between the data centers the connections run over active DWDM devices.A measurement showed that if I deactivate a DC connection in the core, it takes about 400ms until the opposite interface reacts over the DWDM connection and also goes down.In the 400ms, however, traffic will still run over the link to nothing.Now my question:Do you see a problem on the Nutanix side if the switching time is 400ms or are there possibilities to adjust the sensitivity (buffer) of the Nutanix Datastore synchronization to the circumstances?
