Application consistent VM snapshots in Windows Client VMs not possible
Hello everybody, I noticed that application consistent VM snapshots of e.g. Windows 10 Pro VMs with NGT enabled and installed in the VM and verified with ‘ncli ngt list’ doesn’t work and results in the following alert… VSS snapshot is not supported for the VM 'TEST-VM', because VSS software is not installed. and … VSS is enabled but VSS software or pre_freeze/post_thaw scripts are not installed on the guest VM(s) TEST-VM protected by TEST-VM. Using a Windows Server 2016 VM with the respective Protection Domain generates application consistent Nutanix VM snapshots. With Windows 10 VMs it won’t work. Verified in 2 different Nutanix clusters. Clusters are equipped with AOS 5.15.4 LTS version. Nowhere I could find a hint, that Windows 10 VMs are not supported. Regards,Didi7
'Stop Update' feature in LCM
There could be scenarios where LCM (Life Cycle Management) update operation was initiated, and then we need to cancel it in between due to any of the following reasons: 1) LCM operation takes more time than the scheduled maintenance window2) LCM operation was initiated by mistake, and so we want to cancel it soon Starting LCM 220.127.116.11 and later versions, we can now cancel or abort an ongoing LCM update operation using the "Stop Update" feature available on the LCM page via Prism. Whenever this feature is used in LCM, it sets a cancel intent in the Nutanix cluster, which tells LCM to stop the update at the next safe point. The important point is that the update may not be canceled immediately after the cancel intent is invoked since LCM stops it at the next safe point. Hence, we will have to wait until the update reaches the next safe point. This safe point is determined by the LCM framework, which depends on the phase at which the cancel intent was set. Kindly refer to KB-4872 to know m
Offline foundation applet not detecting nodes (Lenovo)
hi Friends, We have a 3-node Lenovo SR530 with IPMI IPs set. We are trying to install and Setup the Cluster remotely (vpn). Below are the details of IPs,XCC IPs - 172.31.199.x (all 3 nodes of same subnet)AHV IPs - 172.31.199.x (all 3 AHVs IPs of same subnet as XCC)CVM IPs - 192.168.5.x (All CVM IPs with thier default IPs) Problem:I have installed Foundation Applet 5.1 and while running on my laptop, its not able to detect the nodes. Any idea on what to check? The other way suggested in one of the forums was execute the cluster create command in one of CVMs. But all the CVMs have same IPs (192.168.5.2). Should I change the IPs of all CVMs with unique IPs matching with AHV and XCC Subnet IPs and then execute cluster create command? How can I know the CVM IP address from the AHV cliFoundation Applet error messageJava Web Start 11.311.2.11Using JRE version 1.8.0_311-b11 Java HotSpot(TM) Client VMJRE expiration date: 19/2/22 12:00 AMconsole.user.home = C:\Users\KishoreSalipalli-------------
License Manager Guide
Welcome to License ManagerThe Nutanix corporate web site includes up-to-date information about AOS software editions.License Manager provides Licensing as a Service (LaaS) by integrating the Nutanix Support portal Licensing page with licensing management and agent software residing on Prism Element and Prism Central clusters. Unlike previous license schemes and work flows that were dependent on specific Nutanix software releases, License Manager is an independent software service residing in your cluster software. You can update it independently from Nutanix software such as AOS, Prism Central, Nutanix Cluster Check, and so on.License Manager provides these features and benefits. Simplified upgrade path. Upgradeable through Life Cycle Manager (LCM), which enables Nutanix to regularly introduce licensing features, functions, and fixes. Upgrades through LCM help ensure your cluster is running the latest licensing agent logic. Streamlined web console interface for Prism Element and Pris
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!
VPC and Flow policy
Hi Team,In the latest release notes I see:Flow Security Policies are not supported for VMs that are on advanced networking stack. An alert is raised for VMs that are part of both VPC and Flow policy, and Flow policies are not enforced for VMs on VPCs.Is there a time frame that this will be resolved? Like this VPC is not ‘really usable’. What is the work around to have some sort of micro segmentation inside VPC? Different vlan inside VPC with an 3th party firewall? Thanks and regards,Peter

Limitations and Guidelines for running Hyper-V on Nutanix clusters
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. Any previous changes to the admin

Karbon 2.3 DVP deployment issues (centralised Prism VPN SIte2Site)
Hi there,We are currently deploying (and testing) Karbon as K8 orchestration platform for all our Nutanix platforms (worldwide). I have failed installation attempts from Prism Central.As a side note, we are using VPN Site2Site from centralised Prism Control and I can reach remote K8 VLAN from distant Nutanix deployment. The reachout tests were done with small VM belonging the the K8 VLAN testing node and via private CIDR (bidirectional tests), but utilizing the same encrypted VPN channel.This is what I’m having from karbon_core.out (PCVM):2021-10-13T21:17:12.687Z ssh.go:153: [DEBUG] [k8s_cluster=RGS-PA-K8-STAGING] On 10.20.25.130:22 executing: docker plugin inspect nutanix2021-10-13T21:17:12.825Z ssh.go:166: [WARN] [k8s_cluster=RGS-PA-K8-STAGING] Run cmd failed: Failed to run command: on host(10.20.25.130:22) cmd(docker plugin inspect nutanix) error: "Process exited with status 1", output: "Error: No such plugin: nutanix\n\n"2021-10-13T21:17:12.825Z sshutils.go:44: [ERROR] [k8s_clust
Enable RDMA on new nodes
Hey everyone - we have 2 brand new nodes that need to be added to an existing cluster. We enabled RDMA when we ran Foundation on that cluster and now need to add 2 additional nodes. Do we run the script to choose which card to enable RDMA on before we add to the cluster? Just looking for guidance on the correct way to ensure it is enabled on the new nodes as well. Thanks!

Changing iLo password via command line
I know this can be done with the NX hardware using the IPMITOOL utility pre-installed, but we’re starting to use HPE hardware and I wondered if anyone knew how to change the iLo administrator login password via cmdlet? We’ve scripted this for NX line and looking to do the same with HPE’s as a part of our deployment scripting.
Enabling and Accessing Calm
Calm is integrated into Prism Central and does not require you to deploy any additional VMs. To start using Calm, you just have to enable Calm from Prism Central. Please ensure, you have met the prerequisites to enable Calm. If the Prism web console is not registered from a Prism Central and the application blueprints have subnet, image or VMs on the Prism web console, the Calm functionality is impacted. Procedure: Log on to Prism Central with your local ADMIN account. For detailed information on how to install and login to Prism Central, see the Prism Central Guide. From the Prism Central UI, click Services ->Calm Click Enable Note that the Enable option appears only if you have logged on to the Prism Central with the local ADMIN account. When Calm is enabled, an extra 8 GiB RAM for large Prism Central and 4 GiB for small Prism Central is allocated automatically to maintain the performance of the infrastructure. To access Calm, click Services → Calm from the entities menu.
