Deployment Success

Dear all We run 2 Clusters with each 3 ESXi and 2 AHV Storage-only Nodes successfully.  Now I want to get rid of VMWare, but all vms were built with vmware, of course I see them in prism. Did anyone ever just deinstall ESXi and replaced it with AHV in a running environment? Alternatively I could move all urgent vms to one Cluster and than install Nutanix from scratch and afterwards migrate the vms to the Nutanix only Cluster. thanks and best regards, Claudia

Can any one list out how many types of Foundation are there eg Foundation Pro, bare metal ..etc. 

What are the 3rd party snapshots? Third-Party snapshots are generated by a third-party backup tool over API calls to our storage. The Nutanix system does not manage this type of snapshots and will keep the snapshots until it receives a deletion instruction from the third-party tool.   The NCC health check aged_third_party_backup_snapshot_check checks the cluster for dangling third-party backup snapshots that may be present for a protection domain. If a third-party backup snapshot has existed in the system for longer than the specified period, this check will raise an alert. These backup snapshots are snapshots that are generated from 3rd party backups (Veeam, Commvault, Rubrik, HYCU, etc.).    The check passes if third-party backup snapshots are not present in the cluster longer than the configured threshold. The default threshold is 7 days, but this threshold value can be modified. The threshold can range from 1 day to 365 days. For more information, examples and solution check out K

Hi Folks,   I have a few machines I would like to convert from IDE to SCSI.   I understand this can be done with acli. The procedure is to clone the ide disk and replace it for the VM.   nutanix@cvm$ acli vm.disk_create <vm_name> clone_from_vmdisk=<vmdisk_UUID> bus=scsi   However, I’d like to do this in PowerShell given I’ve already started developing down that track. I have PowerShell cmdlets to snapshot and shutdown the VM which are recommended steps before performing this task.   I didn’t see a cmdlet to perform the clone and replacement, so I turned to the REST API. I am fairly new to Nutanix to I wanted to get some feedback on whether this is the right approach or at least that its not going to break anything other than my test VM. $uri = "https://$ntxCluster/api/nutanix/v2.0/vms/$($vm.vmid)/disks/attach"$body = '{"uuid":"abcdefg-08h3-4i44-95j0-kl44m82no758","vm_disks":[{"vm_disk_clone":{"disk_address":{"device_bus":"SCSI","device_index":123}}}]}'$headers=@{}$headers.A

As the title said, does anyone know about this interface is used for?

I am struggling to get my VM to unmount the ISO via the PC v3 API.  I’m performing a GET, to get the VM Info, I’ve attempted to update the vm with data_source_reference removed, PC updates, but the iso is still attached.  I see different references with V1 on PE, but can’t seem to do it via v3.  anyone had any luck?

Hi all I have a 3 nodes cluster with RF2. I keep getting the following critical alert: Cluster can not tolerate 1 node failure(s) and guarantee available rebuild capacity Cluster cannot tolerate 1 node failure. Current usage of 6552243087527 bytes exceeds max limit of 9010877278002 bytes. I’m not sure which storage this error is about, the numbers in the error is way to big to what the cluster actually has. I’ve attached screenshot of the storage of the cluster. Any help will be much appreciated.  

I have exported list of all snapshots running on AHV in our environment. On a few snapshots, VM name is empty. I suspect, this is because VM has been deleted without deleting snapshot. Now how to delete such snapshots? Below is example: Snapshot name is “removing ngt” VM-Name Snapshot-Name Creation-Time   servername Test Snapshot 3/19/2019 11:00     removing ngt 2/6/2020 1:00    

We are planning to connect 2 stacked Catalyst 9300 to a Nutanix Cluster. While doing research I found a document recommending the Nexus 9300 and specifying that the Catalyst 9300 wouldn't meet requirements for the Data Center. There was no reasoning for this and I would like to know why the Catalyst 9300 switches are not recommended. Thanks in advance, Ingrid

I share my software to collect information associated with a Nutanix cluster with AHV hypervisor. Link to download NIACtool v2.1

Hi, I am trying to attach a vdisk to a VM. So far I have found that the only way to create and attach a new vdisk to VM is via this API  POST /vms/{uuid}/disks/attach I am trying using this curl expression: curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{  "uuid": "IDEMPOTENT_UUID",  "vm_disks": [    {      "is_cdrom": false,      "is_empty": false,      "is_scsi_pass_through": false,      "is_thin_provisioned": false,      "vm_disk_create": {        "size": 1,        "storage_container_uuid": "CONTAINER_UUID"      }    }  ]}' 'https://10.10.10.10:9440/api/nutanix/v2.0/vms/VM_UUID/disks/attach' \--insecure --basic --user obfuscated_username:obfuscated_password The task fails and error is: “InvalidArgument: Invalid disk size 0”.

I have read that it is only supported using ESXI. If so, what are the other ways to automate the failover.

We are excited to announce the release of Nutanix Move 3.5.0 Adopting new infrastructure platforms often requires a migration of pre-existing systems. Nutanix Move simplifies bulk migration of existing VMs to Nutanix, eliminating the friction associated with onboarding new IT infrastructure. Businesses can quickly leverage the full potential of Nutanix Enterprise Cloud with near-zero VM downtime during the migration from vSphere ESXi, Hyper-V and Amazon AWS to Nutanix AHV and vSphere ESXi to ESXi on Nutanix. Move also support migration of VMs from Nutanix AHV to Amazon AWS. Nutanix Move 3.5.0 is released and the bits are available on the Portal for Download. Move 3.5.0 Release Notes User Guide New features included in this release; Introduced Migration from AWS to ESXi - You can now migrate VMs from AWS to ESXi on Nutanix appliances. Introduced Test Migration - You can now perform a test migration of the VMs on the target environment before the final cutover. Enhanced Move User Interfa

This article describes how to rename the CVM entity in Prism within the AHV environment. This does not change the hostname of the CVM displayed in a console/SSH session as the hostname is a value configured within the CMV OS and is independent of the Controller VM name entity recorded in the Prism entity DB (Insights Data Fabric). It is the same name as in CVM’s XML definition on the AHV host. It can be checked by listing VMs on the host. The name displayed is the name that is shown in the Prism Wen console. Starting from AOS 5.10.10, 5.15 and 5.16, change_cvm_display_name script is available on CVM that can be used to change the display name.   Following is the overview of the rename procedure: Complete the pre-checks:  Name must start with NTNX- and end with -CVM. Only letters, numbers and "-" are supported in the name. CVM should be able to receive a shutdown token. Once CVM has shutdown token it will be turned off.  The script does not put the CVM or the host into mainten
