Deployment Success

When you replace the NIC cards in the Nutanix AHV cluster, it is possible that the new NIC card interfaces are recognised as additional interfaces and are numbered after the existing interfaces. So, for example, in the current AHV node you have 4 interfaces - eth0, eth1, eth2 and eth3 and you replace the NIC card and you see additional interfaces - eth0, eth1, eth2, eth3, eth4 and eth5.  Also, if your host was connected earlier on the replaced NIC card, you will lose the host connectivity. We now have the script in AOS 5.10.10 and AOS 5.15 to get the NIC interfaces re-numbered correctly. If you are running older versions or unable to run the script for any reason, you can use the annual method. Please check the Nutanix portal page

How to get SATADOM firmware Version on Nutanix AHV Hosts. We are planning to upgrade Hardware Firmware and need to upgrade SATADOM firmware before that. Also, it;s not showing under LCM. We are using AOS 5.15.1 and having latest NCC, Foundation installed.

I am trying to find out the User who took the snapshot on AHV Cluster. I did not find the same in Tasks/Events in Prism or through below Command.  acli snapshot.get <SnapshotUUID>

Do you have a VM that you suspect may have been compromised or infected by malicious software (i.e. ransomware) and want to have a means to quickly remove it from your network (so as to not infect other entities)? Do you also want to be able to inspect and work on this VM from a “safe distance” using available forensic tools? Using Flow Microsegmenation, you can accomplish both of these objectives through the use of Quarantine Policies. When configuring Quarantine Policies, you can specify the “Quarantine Method” as either “Strict” or “Forensic”. The “Strict” option isolates the VM from all inbound/outbound traffic entirely. The “Forensic” option allows the limitation of inbound/outbound traffic to that which is specified from the “Add Forensic Tools” tab. For example, this could allow the infected VM to communicate only with another entity that maintains tools for further analysis of the VM. You can find more information regarding Quarantine Policies within the “

Are you still facing DIMM Errors which cause Un-Expected Node Reboots / PSOD and Degraded Node Situations ? And your answer to above question is : YES   Solution: Nutanix has further improved the ability to detect problematic DIMMs and prevent unnecessary service disruption as a result of uncorrectable memory errors (UECC).Whats are DIMM Errors ? A Memory Error is an event that leads to the logical state of one or multiple bits being read differently from how they were last writtenAll About DIMM Errors Nutanix has rolled out a Field Advisory for early detection and error handling related to memory DIMMs

I need to get the iSM and PTAgent versions from AHV clusters running on the Dell XC platform using PowerShell cmdlets. Does anyone know if this is possible? I can’t figure it out and do not think it is possible at this point.

Hi,  We purchad Huawei servers end of last year (check compatibility matrix brought by Nutinix itself https://docplayer.net/136878906-Huawei-hardware-compatibility-list.html and due to Covid19, we were not able to install them until now.  Currently we have 4 servers with part numbers from compatibility matrix 2288Hv5-12 and 2x10G switches for interconnection. Each server has M.2 SSD drives for OS installation configured in RAID 1, while the rest of the disks (SSD of 1.92TB) are in JBOD mode, since that there are 2 RAID cards, one for M.2 and the other for SSD drives respectively. Virtual drive has status OK. During installation process, we receive error message that says the following: “INFO Performing firmware checks for platform Huawei 2288HV5-12

Want to know how to change the default credentials on the cluster? On Nutanix cluster’s if you have the default credentials you will receive an INFO message (default_password_check) in NCC health check informing you the same, you can change your CVM, Hypervisor and IPMI password using the guides below, you can also use script to change it on all nodes at once.

This video demonstrate how Nutanix Calm with the help of Nutanix Move can migrate workloads from the public cloud to on-prem as day-2 operations. This custom integration uses Move APIs to automate the entire process via Calm.   Let the community know how you are using Nutanix Calm and Move. Share your thoughts in the forums.    

We are excited to announce the release of Nutanix Move 3.6.0 Adopting new infrastructure platforms often requires organizations to migrate existing workloads against tight timelines. Nutanix Move simplifies this process with infrastructure-level bulk VM migrations, removing the friction associated with onboarding new infrastructure, and enabling businesses to quickly leverage the full potential of Nutanix Enterprise Cloud, with near-zero VM or application service outage during migrations. Nutanix Move 3.6.0 is released and the bits are available on the portal for download. Release Notes User Guide

Want to check all the alerts on the cluster? Need to resolve them all at once?On the Nutanix web console, you can view a large number of alerts (up to 1000) AND resolve them by navigating to the alerts page from the drop-down on the home screen. But do you want to go the old school way?The Nutanix CLI is designed to display a max number of 100 alerts. You can modify it to show as many alerts as you like and choose how you want to resolve them. For details on how to count the total number of alerts and how to resolve them all in just one command, see KB 1402 in the

Authorization configuration is enabled in two clusters and directed to same Domain controller, which is a VM in one those clusters After that when I use prism API to get stats information of various VMs (I invoked it repeatedly for each VM) it is resulting in 100 % CPU usage in Domain Controller to confirm the same I changed the DC to another VM then the first DC device CPU usage got reduced and second DC device CPU usage raised to 100% API used : /PrismGateway/services/rest/v1/vms/<uuid>  

Hi, I have built up a Darksite LCM running in my own local network and have Internet access to download necessary Darksite bundles for upgrading. In my testing evironment, the server works flawlessly with Dell XC cluster and Nutanix cluster as well but with DX cluster, it cannot provide any firmware update at this time though currently at least 1 node in our cluster is running on an old SPP version (2019.03.01). For our DX environment: Node1: 2020.03.0 SPP Node2: unverified? (LCM cannot detect the SPP version) Node3: 2019.03.01 SPP Does anyone have any idea on this case?  

There are two ways of  checking certificate revocation in client authentication: Using OSCP (nCLI) Using CRL- Certificate revocation lists (nCLI)   OCSP is the recommended method for checking certificate revocation in client authentication. You can enable certificate revocation checking using the OSCP method through the command line interface (nCLI).   What is OCSP ? The Online Certificate Status Protocol is an Internet protocol used for obtaining the revocation status of an

It enables administrators to take inventory of the firmware and software in their Nutanix environment and perform updates in a simple, cluster-aware, fashion. LCM adds a management layer and logic that deploys firmware/software upgrades taking into account upgrade paths and potential conflicts between versions.  LCM performs two operations: Inventory: Detects what can be managed on a cluster. Update: Performs an update to a certain version. With Release of LCM 2.3.2 we have introduced a new page which shows best practices guide and redirect you to FAQ’s troubleshoot guide  

Hi,I need an older version of Foundation and AOS. Where can I find them?I can only find the latest version to download.I need ,Nutanix Acropolis Operating System (AOS) 5.5.8Nutanix Foundation 4.3.2Nutanix AHV 20170830.185 Thank you.

Nutanix cluster works with the vDS and you can use the following guidelines and recommendations to configure the vmk and VM interfaces to be part of the vDS. Nutanix recommendations for implementation Keep the vSwitchNutanix, the vmkernel port (vmk-iscsi-pg), and the Nutanix Controller VM's virtual machine port group (svm-iscsi-pg) configuration intact. It should remain as a standard vSwitch and should not be migrated over to the vDS. Migrating the vSwitchNutanix to the vDS causes issues with upgrade, and also controller VM data path communication.

Hello, guys Please, help me with these two points: I’m searching for the spec int value that the sizer uses. For example, I see that a default processor is E5 2680v2, 42.31 specInt. But I searched on the website of Spec.org and I couldn’t find that and the other serverals values that use Nutanix sizer, as is shown in the picture. Maybe I search on the incorrect section of Spec.org, 2006? 2017? Please help.   I was wondering if the applied weight value is published in any website of Intel. I figured out that it is a fix value: 7.3 per processor for Xeon Gold 6244, for example. I wrote down the applied weights for 3,4,5 and 6-node configuration (dual-processor) and the calculations works this way: Applied wieight in 3-node cluster: 43.8 (7.3x6) Applied wieight in 4-node cl

The Nutanix cluster in Vcenter must be configured according to Nutanix best practices.    A quick checklist for the recommended settings review is as follows:   vSphere HA Settings   Enable host monitoring   Enable admission control and use the percentage-based policy with a value based on the number of nodes in the cluster.

Disk structure of a CVMThe CVM is the core of the AOS clusters, but have ever wondered how disk layout exists within them?I provide a brief overview of its structure in the following post.The main thing that most of you are familiar with already, is that the LSI controller is passed directly to the CVM in order for it to have direct access to the disks in the node. When combining all the disks space from all the CVMs within the cluster it provides the unified software define storage pool used to store your data.That’s why when you run “df -h” in the CVMs you will see the data disks mounted in the following mount point:

Acropolis Operating System upgrades happen across the cluster, one CVM at a time. Here is the next installation of the Upgrade Series as promised to provide you quick tips and tricks to plan and execute your upgrade activities with ease.   In simple words, AOS is the Operating System running on the Controller VMs(CVM) in the cluster and is critical in handling the data I/O from the user VMs in the cluster. AOS can be called the core of Nutanix Hyper-converged infrastructure.   As reference documents, you can check the below Guides: AOS Advanced Administration Guide
