Deployment Success

Hi AllDoes anyone know what causes the data in the picture to be lost(CPU&MMemory)? 

I may be having a case of the stupids, but I am trying to find the PowerShell cmdlet that will let you pull information of categories assigned to a VM. I’m running the Get-NTNXVM cmdlet but I do not see the category listed for the VM. Additionally, when I run a Get-NTNXTag it returns “No data found”. Does anyone know how I can pull category info for VMs via PowerShell?

Hi!We have two Nutanix clusters running ESXi v6.7.0 with a Horizon 7 VDI environment on each.  We needed to be able to sync Horizon AppVolumes between the clusters via some common storage.The solution we were set up with was a FreeNAS VM on one cluster publishing an NFS share which was then attached to the hosts in both clusters.  We weren’t bothered about high availability as it’s not an issue if the replication of the appvolumes goes down sometimes as it’s only needed if appvolumes are being changed or their assignments to users is changing.After an NCC upgrade, Prism Element now flags up this external datastore as unsupported.  I’m struggling to find out from Support what the actual magnitude of risk is here to the stability of the clusters (especially when it comes to upgrading firmwares, AOS etc).Does anyone here have any thoughts on this situation please?Thanks for reading!

During VM creation  in nutanix ESXI, if we select the thin provisioning and submit the operation once , it shows thick provisioning if we see the disk settings. what will be the issue ?

When no DHCP server is available, or where creating a scope large enough for X-Ray VMs is not possible, use zero-configuration for self-assigned IP addressing. Zero-configuration networking is a standard for IP addressing where a host self-assigns an IP address. X-Ray uses IPv4. which uses the reserved addresses 169.254.0.0/16. This feature eliminates the need for manual IP address configuration or DHCP.  To use zero-configuration networking, configure the workload VMs and the second NIC of the deployed X-Ray VM to use the same layer-2 network. For ESXi, the .ova adds the second NIC automatically. For AHV, add the second NIC manually. The second NIC automatically picks up the zero-configuration settings when you add it, so no extra configuration is necessary. Enabling IPMI Discovery on ESXi Enable web-based enterprise management (WBEM) for IPMI discovery on ESXi  On ESXi 6.5, the IPMI discovery process is disabled by default, which results in unsuccessful connections during target crea

You can monitor the Mine cluster health and activity through Prism. To determine the AOS version of your Mine the cluster is running, go to About Nutanix option under user_name drop-down list in Prism main menu. Mine with Veeam DashboardThe Prism web console includes a custom Mine with Veeam dashboard specific to a Mine™ cluster, which appears by default when you first log on to Prism. To view this custom dashboard at any time, select Mine with Veeam from the pull-down list on the far left of the main menu.The custom dashboard displays the following eight information tiles (widgets): Cluster. The cluster tile provides quick visual indicators for the following components: cluster health (overall), Veeam implementation, Mine™ components, and storage capacity (available). Green indicates a healthy component, yellow indicates a warning condition, and red indicates a critical condition. Click the Launch Console link to open a Veeam console. Click the Mine Platform link to open the Mi

Hi guys,I want to run some tests on a local system, so I created two VMs that are isolated from my production network.So, I created a network in the cluster just to be used by these two VMs. This network does not exist in production, only within the cluster.I added the NIC for this network on both VMs. But even so VMs do not communicate, I cannot ping or access via SSH from one VM to another.This type of configuration, just for testing, is not possible with AHV \ AOS?     

So my 1st dive into Nutanix and I’m stuck at the first hurdle. I’ve setup a 1 node cluster to start with on a supermicro server with a decent enough spec and am just getting it ready to start experimenting but I can’t get the File Server updated. Everything else is running current versions but I have the below. I’ve had a quick look for some CLI guides but can’t see how to get more info on why this would be stuck. Very odd considering everything else updated without issue. Rules out the normal access, DNS issues etc. Any idea how I can clear these jobs? Rebooting etc does not clear them.I was just able to update NCC from 4.2.0.2 to 4.3 via the same method without issue. Thanks!Mark  

Whenever I export the vm list, I never see the creation date of each vm.How can I see the creation date of each vm, without using PrismCentral?Is there a tool, or script to see the creation date of each vm?Please help

 If you are unable to add hosts and storage to SCVMM by using the utility provided by Nutanix, you can add the hosts and storage to SCVMM by using the SCVMM user interface. Procedure: Login to the SCVMM user interface and click VMs and Services.

 Nutanix clusters running Hyper-V have the following limitations. Certain limitations might be attributable to other software or hardware vendors: Guidelines: Hyper-V 2016 clusters and support for Windows Server 2016.  VHD Set files (.vhds) are a new shared Virtual Disk model for guest clusters in Microsoft Server 2016 and are not supported. You can import existing shared .vhdx disks to Windows Server 2016 clusters. New VHDX format sharing is supported. Only fixed-size VHDX sharing is supported. Use the PowerShellAdd-VMHardDiskDrive command to attach any existing or new VHDX file in shared mode to VMs.  For example: Add-VMHardDiskDrive -VMName Node1 -Path \\gogo\smbcontainer\TestDisk\Shared.vhdx -SupportPersistentReservations. Upgrading Hyper-V Hypervisor Hosts  When upgrading hosts to Hyper-V 2016, 2019 and later versions, the local administrator user name and password is reset to the default administrator name Administrator and password nutanix/4u.

For a node to join a Nutanix cluster, it must have a hypervisor and AOS combination that Nutanix supports. AOS is the operating system of the Nutanix Controller VM, which is a VM that must be running in the hypervisor to provide Nutanix-specific functionality. Find the complete list of supported hypervisor/AOS combinations at https://portal.nutanix.com/page/documents/compatibility-matrixFoundation is the official deployment software of Nutanix. Foundation allows you to configure a pre-imaged node, or image a node with a hypervisor and an AOS of your choice. Foundation also allows you to form a cluster out of nodes whose hypervisor and AOS versions are the same, with or without re-imaging. Foundation is available for download at https://portal.nutanix.com/#/page/Foundation.If you already have a running cluster and want to add nodes to it, you must use the Expand Cluster option in Prism, instead of using FoundationNetwork requirementsWhen configuring a Nutanix block a set of IP addresses

HyperVisor - ESXi 6.7U3Mostly Windows VMsI’m sure there’s good reason for this and it's probably to do with the way SQL handles memory but when I check the memory usage from Prism or Prism Central for a VM that’s running SQL it’s not accurately reflecting what the VM is actually using.  For example, from within the VM if I fire up task manager or even perfmon it will report the memory usage at say 95% whereas from Prism it reports the VM as using 25%.I need to generate a report for a collection of SQL VMs and application servers but I think for the SQL VMs I'm going to have to provide perfmon screenshots or something.Can anyone explain to me in simple terms why this is happening?

With AHV-20190916.189, Nutanix supports Directly Attached Volume Groups in a Guest VM Cluster. On AHV clusters, you can create a guest VM cluster by directly attaching a volume group to guest VMs.After you attach a volume group to guest VMs, vDisks appear as SCSI devices to the guest operating system and you do not need to set up any in-guest connections when you are creating a guest cluster. If you directly attach volume groups to guest VMs, you can seamlessly share vDisks across VMs in the guest cluster.You can directly attach a volume group to guest VMs to create the following guest clusters:1. Microsoft Failover Cluster (MSFT)2. Red Hat Enterprise Linux (RHEL) Cluster For more details, refer to following:Guest VM Cluster Configuration (AHV Only)Create Guest VM Clusters by using iSCSIAcropolis Release Notes
