Nutanix Cloud Infrastructure

Can we change the CVM password to something else, and will it affect the Nutanix services if we do so?Thanks in advance :)

I have a problem about Recover VM in Rubric. I have made several attempts to recover the vm.As additional info:1. The VM is in Nutanix, previously the SATA storage bus and has been converted to a SCSI storage bus2. Nutanix has been upgraded AOS version 5.20.1.1 LTS                                               NCC version 4.2.0.2                                               Foundation version 5.0.4-ed564a883. RUBRIK has been upgraded to version 5.3.3-19316 

I want to backup the Nutanix AHV VMs, ，but I dont’t kown how to get the list of changed data blocks.In this article (Nutanix 5.0 Features Overview (Beyond Marketing) – Part 2), I see the following:Nutanix CBT utilizes the new REST 3.0 API that can be used to query for the changed meta-data regions given any two snapshots of a virtual disk or virtual machine. The approach is valuable for taking incremental and differential backups; and even useful while taking full backups because the API identifies regions that are spare (zeroed), therefore saving on read operations. I read the api documentations (PRISM v2.0 and PRISM v3) carefully, But I don’t see find a useful api.Does anyone tell me which API to use how to use it?Thank you.

Hi, I just deployed my 2 clusters on separated Data Center. Right now i have no Link between them besides Internet (No VPN). Can i use NAT Destination of IP Public of each Data Center for the target of Remote Sites Configuration?Example:Data Center A : 123.234.123.234:2020 > NAT Destination to > 250.250.123.123:2020Data Center B : 234.123.234.123:2020 > NAT Destination to > 200.200.123.123:2020Can we configure like that in order to Remote Sites Configuration to work?

I have a problem with a CVM that won’t boot. This is on a semi-retired production cluster (not CE) that has no workloads running on it.I found the console output in /tmp/NTNX.serial.out.0 and I can see it trying to enable RAID devices, scan for a uuid marker and find 2 of them, then abort and unload the mpt3sas kernel module before trying again in 5 seconds. This repeats a few times before the hypervisor resets it and it starts booting again.The most relevant sections of the log (copious kernel taint messages removed) are [ 9.543553] sd 2:0:3:0: [sdd] Attached SCSI disksvmboot: === SVMBOOTmdadm main: failed to get exclusive lock on mapfile[ 9.790075] md: md127 stopped.mdadm: ignoring /dev/sdb3 as it reports /dev/sda3 as failed[ 9.794087] md/raid1:md127: active with 1 out of 2 mirrors[ 9.796034] md127: detected capacity change from 0 to 42915069952mdadm: /dev/md/phoenix:2 has been started with 1 drive (out of 2).[ 9.808602] md: md126 stopped.[ 9.813330] md/raid1:md126:

We would like to upgrade the hypervisor on our Nutanix cluster from Windows server 2012R2 to windows server 2016.Kindly could you please advice the steps to do that and avoid any issues in upgrading.

Since its inception; the Nutanix platform has offered customers a robust set of data protection technologies.  Many of our customers leverage these capabilities as a part of their DR strategy.Now, with the advent of Nutanix Clusters (on AWS bare metal today) extending the capabilities enabled by the data protection suite to the public cloud is now a reality.  Nutanix Clusters on AWS deploys the Nutanix HCI stack onto AWS bare metal instances.  Provisioned via a customer portal customers can have a public cloud resident Nutanix Cluster operational in very short order.At which point they’re ready to leverage the public cloud as a part of their DR strategy; while maintaining a familiar operator experience: 

I make no bones about it, bare-metal nodes in AWS is pricey. The questions becomes if we want to save money and have DR with AWS, how do keep the number of nodes small until we failover?In AWS all the Nutanix rules still apply. We need a minimum of a three-node cluster to get started. If we have enough storage capacity, we can keep accepting replications from an on-prem cluster and not worry about CPU and memory constraints. You could also use your on-prem AHV supported backup software to backup directly to S3. Then when you have an outage, you could quickly build a Nutanix Cluster in AWS and start restoring the data to that cluster.DR on the skinnyI was a asked to automate the process of adding nodes to a small Nutanix Cluster in AWS and then start a failover using Leap (DR runbooks) and X-play(automates actions based of events and alerts) in Prism Central (PC).  The below video is what I came up with.  The code to add a node via API from the Cluster portal is listed here:https://gith

Hi Folks,I have some SQL servers running on Nutanix without using ‘Flash’ mode for those. I am facing disk latency alerts for vmdisks on those SQL server VMs. Is there any way to identify if the VM disks are on HDD or SSD?

Hi Folks,I want to virtualise 2 SQL servers on Cisco UCS hardware to Nutanix. I found references for Xtract for DB, however it seems it is a legacy tool as I am not able to get much information on it. Nutanix ‘Move’ seems to be used for VM migration.On Nutanix I have ESXi, so i know we can use ‘Vmware Converter’, but I would like to know if there is any solution from Nutanix for this.Can some one please guide me about the ways I can achieve this P2V of SQL servers?

How do I copy a snapshot configuration to a CD disk or laptop HD? Worse case scenario I lose the NTNX configuration so, I’ll need to reimage my NTNX from last good configuration. Please help...

I will looking to migrate from VMware to AHV in the next few weeks. As I understand it, it is not possible to schedule the state of a VM say for Shutdown or Power On, as you can do in VMware. Is there a workaround and is this on the roadmap?

When I searched the documentation, it was said that scsi-3 pr3 is supported when attaching volume from AOS 5.17.my curiosity1. In versions prior to 5.17, when allocating a shared volume for vm redundancy configuration, if you use Attach instead of using iscsi-initiator, does it not work?2. Considering I/O speed and stability, which do you think is better, mounting a volume through iscsi-initiator or connecting to a VM as a direct attach?

Hi, AHV is based on KVM, but I can't find any documentation that states that you actuelly can run/move KVM VMs on AHV. Can anyone confirm this? We have a customer who wishes to move their KVM VMs to our AHV environment. :) So we want to confirm that it is possible. Best regards Peter

We are running our data center on AHV and would like to store backups in the cloud. (preferably archive tier). What options do we have?  From my understanding, we can leverage the use of VTL’s in the form of AWS storage gateway or Starwind VTL to push our backups to the cloud, but since my knowledge of VTLs and cloud are minimal, I’m struggling to find how to accomplish this. Can someone point me towards articles that will guide me through this? Specifically, I’m not sure how to make that connection from Nutanix to a VTL or storage gateway. Would iSCSI be involved? Any help would be much appreciated! 

Hi, we are a IP Telephony company and we are looking for an option to have a better backup system on our servers.We currently have 2 servers running ESXi. One live server with all our VM for our clients and one backup server. Nutanix seems like a good option for us to be able to have a backup system always live and not having to boot up any VM manually.If I wanted to start using Nutanix what would you recommend as best practice for a switch from ESXi to Nutanix?I just started looking into Nutanix and it seems like a great option with all the redundancy and self healing feature. I was wondering where I can find prices for the OS or access to the technical support. I can’t find any option list of subscription or price range for their OS.

Hi - I’m having an issue with a new installation of Nutanix on AHV (single node cluster) that I’m hoping someone hear can help with.Basically, using Prism, when I attempt to create a new VM the process fails with the error “VM with ID ‘*********’ was not found”. However, if I attempt to add a VM without a new disk, it successfully creates the VM but I can’t add a disk to it, error “Operation Failed: InternalException”.I’ve been able to upload my ISOs for installation etc. and of course the CVM is seemingly working fine. Any ideas what could be wrong? Many thanks.

I have question about remote site's snapshot.When we restore the VM by snapshot from origal siteI have question about remote site's snapshot.When we restore the VM by snapshot from origal siteWhen we restore VM, it will probably be a clone of the original site's VM, so I can understand NIC MAC Address can be changed.However, I hope to know does IP addresses also be change or not. 

Nutanix recommends the following best practices for implementing disaster recovery using Leap. Along with these recommendations, there are specific recommendations for data protection with Synchronous replication (0 RPO).For data protection with Synchronous replication recommendations, see Recommendations for Synchronous Replication.General Recommendations Create all Leap entities (protection policies, recovery plans, and VM categories) at the primary site, where the VMs exist. Upgrade the Prism Central before upgrading the Prism Element running on the clusters registered to Prism Central. Disable Synchronous replication before unpairing the sites.If you unpair the sites while the guest VMs in the Nutanix clusters are still in synchronization, the Nutanix cluster becomes unstable. For more information about disabling Synchronous replication, see Disabling the Synchronous Replication (from 5.12 to 5.17 only). Recommendation for Virtual NetworksDo not create virtual networks that hav

Is there the possibility of using the microVM concept in Nutanix? Are solutions like firecracker (https://firecracker-microvm.github.io/) possible with Nutanix?As I understand it is not possible to nested virtualization with Nutanix (https://next.nutanix.com/server-virtualization-27/nested-virtualization-33423), so is there any provision for a feature that enables the use of microVMs with Nutanix?

Virtual Machine High Availability (VMHA) ensures that VMs restart on another AHV host in the cluster if a host fails. VMHA considers RAM when calculating available resources throughout the cluster for starting VMs. VMHA respects affinity and anti-affinity rules. For example, with VM-host affinity rules, VMHA does not start a VM pinned to AHV host 1 and host 2 on another host when those two are down unless the affinity rule specifies an alternate host. There are two VM high availability modes:  Default: This mode requires no configuration and is included by default when installing an AHV-based Nutanix cluster. When an AHV host becomes unavailable, the VMs that were running on the failed AHV host restart on the remaining hosts, depending on the available resources. If the remaining hosts do not have sufficient resources, some of the failed VMs may not restart.  Guarantee This non-default configuration reserves space throughout the AHV hosts in the cluster to guarantee that all VMs can re

Since a week, a virtual Windows Server is unreachable after a backup is created with Rubrik.In the Windows Event log, the following error is raised.(Event ID 129) Reset to device, \Device\RaidPort0, was issued.We are using VirtIo drivers 1.1.6.18 on this Server 2019 instance?Anyone familiar with this error message?regards,Bart

We have Nutanix 3 Node Cluster with ESXI 7 , I am planing for DR with Nutanix.What are the DR option available in Nutanix? Is it using VMWare SRM or Nutanix Protection Domain? what is the minimal RPO and RTO? is it possible realtime replication ?

Anyone running Traditional SQL Clusters on a Nutanix / HyperV implementation?
