Deployment Success

Hi, I'm planning a 3 node Lenovo 2320-E node. The most it will ever grow, is to a 4 node. Each node has a 4 x 1/10Gb BaseT network card (IMM/IPMI) connection is separate. The max number of VM's will probably never exceed 16 (Windows 2008R2/Windows 2016 ) The priority of importance in this case is: Reliability Lowest Cost Performance Network Config Option 1 (1 switch 1 GB ports only): Purchase 1 switch with dual hot-swap power supplies. (Not to jinx myself, but switches have a low fail rate) Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 2 (2 switches 1GB ports only) Purchase 2 switches, each with a single power supply Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 3 (1 switch with both 1 & 10Gb BaseT) Purchase a switch that supports mixed 1 & 10Gb BaseT ports Setup each node as balance-slb and use 2 x 10Gb (of the 4 ports) My understanding of balance-slb is I will have 4Gb of throug

Hi Friends, It's nice joining you in this wonderful community. I'm Ridwan Oladipupo from Algorism Limited, Nigeria. I'm representing my company as a System Engineer saddled with the responsibility of handling the technicalities of Nutanix during POC. Please I'm absolutely new to the system, I've started with nutanix school, but I felt that is not sufficient enough to get the Job done. I need to get with the guys doing the job. I would be glad if anyone can volunteer to mentor me on this solution. Thanks in anticipation.

Hi, I want to automate the procedure of node imaging. I have exported the configuration file for foundation. Is there command line to image node with configuration file?

Remote authentication is one of those things that once set up correctly just work. We do not notice it, we simply put in our credentials and use it.It takes some understanding and a tiny bit of thinking ahead when mapping AOS roles and permissions to LDAP/AD users and user groups.So where to start?First, follow Prism Element Security Guide: Configuring Authentication to set up remote authentication.Run NCC Health Check: ldap_config_check.For any issues leverage KBs:KB-2066 Unable to Log In to the Prism web console using Group LDAP authenticationKB-3363 Prism: Troubleshooting LDAP Issues for Prism Log On For those of you PowerShell fans there is a little bit of CLI available:PowerShell Cmdlets Reference: LDAPConnection PowerShell Cmdlets Reference: Domain

Hey guys,I don't have Nutanix and I want to practice on Nutanix - is there virtual image I can use for practice?

Hello all, i'm trying to build a very simple home lab so i can get through the NCP cert, hopefully prior to our new nutanix gear arrives at my work. at home i have an i7 8700k, 16gb of ram, and several HDDs. i also have a NAS device. i run windows 10 on my one available machine. my issue is this: i can only feasibly spare 12 gb of ram, and i dont have a dedicated 200 GB SSD, but i have several terabytes of HDD storage available. is it possible for me to get a home lab up and running with this config? using VMWare Workstation or something similar? thanks, Tony

Hi, I can see both the NGT and vmware tools in a VM deployed in Nutanix Esxi cluster,when access it via prism? Which one I can able to install?Is there any difference between NGT and Vmware tools?or shall I install NGT in a VM deployed in Nutanix ESxi cluster?Please clarify Regards Jai

There appears to be an issue with the latest Powershell Cmdlets for Version 5.11 that reports itself as Version 5.1.1 (not 5.11) so there is a mismatch. This will bring up a Warning dialogue box asking you if you want to continue with this mismatch (Cluster Version 5.11 and CmdLets Version 5.1.1). This can affect any Powershell Automation Scripts you have running that will be waiting for user intervention! You can change the Nutanix Connection method to Force the Connection using the following syntax: Connect-NTNXCluster -Server "Your server here" -UserName "Your user" -Password "Your password" -AcceptInvalidSSLCerts -ForcedConnection Note: It is the ForcedConnection that enables the bypass of the mismatch for your scripts. Hopefully they will update the Version with the next iteration of the Cmdlets without the apparent typo of 5.1.1 instead of 5.11. Please feel free to "Like" to mark as "Best Answer" Kind Regards Andy @andymlloyd

Is it possible to create DMZ network VM with single physical UpLink?

Nutanix REST API gives flexibility to a developer or an administrator to create scripts which can execute administrative jobs on a Nutanix cluster. Using the API, you can request information about different entities in the cluster or even change some configuration. Everyone at the end of the day wants to make sure that their infrastructure is fully secure.  So what about Authentication? What kind of authentication does REST API require?   Nutanix support multiple authentication options. Want to know about them and how to configure and use them in your scripts? Give the following KB a readKB-2257 Want to know more about Nutanix REST API and different dev tools we provide? Log on to https://www.nutanix.dev/ Want to know more about Nutanix REST API Explorer and play around(with caution) with the APIs in your Nutanix Cluster? REST API Explorer

Hello, I will need to power off a "Metro Standby Site", which has VMs running on it. I would like to manually migrate those VMs to the primary (active) site and Shut down / Power Off the nodes in the Standby site approx. 24-36 hours. All VMs need to be running on the active side and no VMs are to be restarted (RTO + RPO =0). The steps I propose to take to achieve the goal are as follows: I have included as much environment info as possible. Any insight or corrections to this process are welcome. Thanks in Advance Phase I (Configure Standby Site) Disable/suspend the (x1) asynch PD (from Primary) Update VMware DRS Rules (Manual) (from Primary) Disable HA Manually perform vMotion of all VMs to active site. Configured VM affinities to the hosts of the primary site and set the DRS rules to Fully Automated. Create new VMGroup and Host Group if needed I do not want to disable DRS and lose my DRS Affinity Rules Disable Metro per PD (x3) (from Primary) Phase II (Power Off

Can you use a FC card in one node of a Nutanix cluster to do a storage Vmotion / migration to the New esxi Hosts in the cluster ? FC card will present the current VMFS partition to the new esxi host running in the cluster .Then storage vmotion the vm's across to the new storage( NFS partition in the nutanix cluster ) Is this possible ? Prefered option as NFS would only be on a 1 gig network and we need to do this quickly Any input will be appreciated ?

Hello, Where from i can download prism central ova (for vmware)? I used several links, but always i am redirected to support portal. But i have community account only... Regards Mindaugas

While we the topic of VirtIO drivers has already been touched in Sarab’s post on Installing Windows VM and VirtIO drivers, we would like to bring two more KBs to your attention.One is on AHV | How to install VirtIO drivers for Microsoft Windows Server 2008 (KB-5666) and the other one is AHV | Nutanix VirtIO drivers for Windows Server 2019 (KB-6495).N.B! Nutanix does not release or maintain VirtIO drivers for Microsoft Windows Server 2008. However, you can still use stable VirtIO drivers available from Fedora project website.Nutanix recommends to use the Stable VirtIO-Win drivers.

In this post we will go through the steps required to shut down and power off all hosts in a VMware vSphere cluster on AOS to perform maintenance or other tasks such as physical hardware relocation. Note: Upgrade to the most recent version of NCC before proceeding with the following steps. Points to consider before attempting to shutdown a vSphere Cluster running atop AOS:Cluster health and Resiliency (Prism Dashboard) vCenter hosted on the same AOS cluster or outside?

For a nutanix cluster to be able to install a newly released hypervisor, the information about it must be already in iso_whitelist file.  This file can be downloaded from Nutanix portal (search for ESXi 6.7 U3) and is required when installing/upgrading hyperviosr using prism one-click.ESXi 6.7 U3 (built number 14320388),  has been out as of Aug, 20, 2019. It is Nutanix policy to support newly release hypervisors within 90 days after they are release by the hyperviosr vendors.As of this writing (Nov 18, 2019), nutanix has released the iso file for this release and is supporting installation of this built on Nutanix clusters 5.10..6 and above.Below is a public KB regarding the support for this release:https://portal.nutanix.com/#/page/kbs/details?targetId=kA00e000000CsgLCAS 

Maintaining a big infrastructure requires planning and knowing your architecture inside and out.Let's say, sometimes you need to check the upgrade history of different components in your cluster.Sometimes you want to know when you last upgraded AOS or Nutanix Files.The timestamp of the upgrade.Let's say you want to plan a future upgrade and creating a time-line and want to know when you upgraded the software last and at which version.We all need this information, either to maintain a proper record of our cluster infrastructure or to plan the future upgrade.So how can we achieve this?Give the following Knowledge base article a read to find out the upgrade history of different components in your cluster and plan your future upgrades accordingly.KB-1151 Want to know how upgrades work in Nutanix? Try going through the following Knowledge Base to understand how upgrades work in Nutanix architecture.KB-6945 Have a question regarding upgrade workflow? Drop a comment and let’s start a conversa

Could we get some more documentation on this command?Clone-NTNXVirtualMachineOne of the required parameters is -SpecListI would like some clarification on this parameter and how to use it. Is this an array of values? Am I linking to a csv or json file?An example would be nice.Using the UI, I currently clone a reference image to create vm’s and I would love to get a PS script to work to do the same. I can get it to work with the ACLI commands but PS is a bit more versatile and I believe I could get it to do more if I understood this command and specifically this parameter better.

Security is the backbone of any infrastructure, so it is always recommended to set a strong industry-standard password for different components in your environment.Let’s say you want to implement a strong security password policy and have a need to modify the CVM and IPMI password in your environment but confused from where to start.Let us break the components for you: Modifying the CVM PasswordLogin in to the CVM.Change the admin password using the commandadmin@cvm$ passwd After you have successfully changed the password, the new password is synchronized across all Controller VMs in the cluster so you only need to follow the steps on just one CVM. Want to know more about the Nutanix password policy guidelines and steps for the above procedure Modify the CVM password. Modifying the IPMI passwordLogin to the IPMI Web Interface Click Configuration -> Users -> Administrative UserClick Modify and modify the password by entering the new password. What if you don’t have access to IPMI

At the end of guest OS installation the VM is rebooted but it doesn't automatically boot to the vHDD. How can I set it to boot automatically from the disk with installed guest OS? By default, AHV uses CD-ROM as the first boot device for VMs, followed by hard disk, then NIC. Please follow steps described below to override this behavior and choose a specific boot device. Things to consider:CD-ROM or hard disk can be selected as boot device in Prism UI. Network adapter can only be configured as boot device via acli. Selecting NIC as boot device may be required to boot VM from PXE server. Power cycle is required to apply boot device change. Resetting or rebooting VM is not enough. If boot device not explicitly selected, then all VMs will try to boot from all CD-ROM devices. If all CD-ROMs are empty or do not contain bootable image, then VM will only try to boot from hard disk with lowest index. If VM is configured to boot from network and there is no PXE server available, VM will not try t

I am having an issue adding a share to a new AFS instance where it reports “iSCSI discovery of targets failed to iSCSI portal xxx.xxx.10.5. Ensure that the stargate external data services IP and the CVM IPs are reachable from FSVM.” I have confirmed the CVM IP’s and FSVM IP’s are all bound to the eth0 interface of there respective devices and are all in the same xxx.xxx.10.xxx network segment.  All devices can ping all IP’s in the range so at least basic comms are working. I am sure I am missing something obvious but not sure where to go from here.  Suggestions please!

I just deployed a Witness VM (ESXi) for our first 2 node cluster and after setting the IP and reboot it gets the host name NTNX-<IP NUMBER>-A-CVM.Since it seems the witness VM is a kind of CVM I assume it wants to use the NTNX-<NAME>-CVM naming convention or it is OK to set the host name to whatever?Worked fine using  “sudo /usr/local/nutanix/cluster/bin/change_cvm_hostname <hostname>” to set the host name. 

For Files Analytics, are the ports required TCP or UDP?  I know that the ports to open are 7, 3000, 29092 but just wanted to be clear on tcp or udp. Thanks
