Hello - We created a custom DISK Image and need to automate the upload to Nutanix. Is there a way for us to programatically upload an image using powershell?

Phoenix is an ISO-based installer that you can use to perform the following installation tasks on bare-metal hardware one node at a time: Configuring hypervisor settings, virtual switches, and so on after you install a hypervisor on a replacement host boot disk. This option does not require you to include AOS and hypervisor installers in the Phoenix ISO image. Installing the Controller VM, which runs AOS. This option requires you to include the AOS installer in the Phoenix ISO image. Installing the hypervisor on a new or replacement node. This is an alternative to installing the hypervisor by the use of the hypervisor manufacturer's ISO and reduces the two-step procedure—that of first

While maintaining your Nutanix environment, there is a need to apply patches to keep everything running smoothly. Some of these patches require reboot of the CVM or Hosts to take effect.For example, rebooting all hosts in a cluster means manually putting the host in maintenance mode, evacuating the VMs, turning off the CVM, rebooting the host, waiting for the CVM and host to boot up, and confirming the cluster data resiliency is OK before proceeding to the next host. As you can see, there is a lot of manual work involved.However, there is a simpler solution: leveraging the rolling reboot script. The script utilizes our shutdown token feature to ensure that the node is up and running before proceeding to the next node. If you are using AHV, the script will be available in Prism. For ESXi hypervisors and for more robust options (even for AHV), there is a command line option found in KB 4723More information about the prerequisites (please read this before using) an

I need to upgrade vcenter to 7.0 in my lab, but I can find confirmation that will work with AOS, version 5.15.1.1 LTS.Actual 6.7U3 is installed, and AOS is on ESXI 6.7U3, i can move the hosts later, when will published in the compatibility matrix (dell R640), but I have to upgrade ASAP the vcenter, thanks for the support!

Hi,I am trying to monitor the CPU ready time (hypervisor.cpu_ready_time_ppm) for the VMs on AHV but the metrics available via the API does not provide this particular metric.The host metrics available via the API areHost_hypervisor_avg_io_latency_usecsHost_hypervisor_avg_read_io_latency_usecsHost_hypervisor_avg_write_io_latency_usecsHost_hypervisor_cpu_usage_ppmHost_hypervisor_io_bandwidth_kbpsHost_hypervisor_memory_usage_ppmHost_hypervisor_num_ioHost_hypervisor_num_iopsHost_hypervisor_num_read_ioHost_hypervisor_num_read_iopsHost_hypervisor_num_received_bytesHost_hypervisor_num_transmitted_bytesHost_hypervisor_num_write_ioHost_hypervisor_num_write_iopsHost_hypervisor_read_io_bandwidth_kbpsHost_hypervisor_timespan_usecsHost_hypervisor_total_io_size_kbytesHost_hypervisor_total_io_time_usecsHost_hypervisor_total_read_io_size_kbytesHost_hypervisor_total_

 key-based SSH access to a cluster is supported. Adding a key through the Prism web console provides key-based access to the cluster, Controller VM, and hypervisor host. Each node employs a public/private key pair, and the cluster is made secure by distributing and using these keys. Users can create a key pair (or multiple key pairs) and add the public keys to enable key-based SSH access. However, when site security requirements do not allow such access, you can remove all public keys to prevent SSH access. To control key-based SSH access to the cluster, do the following: Steps:Click the gear icon in the main menu and then select Cluster Lockdown in the Settings page.The Cluster Lockdown dialog box appears. Enabled public keys (if any) are listed in this window. To disable (or enable) remote login access, uncheck (check) theEnable Remote Login with Password box. Remote login access is enabled by default. To add a ne

With the introduction of download pages on the Nutanix Support Portal, The download bundle links now come with an expiry time set to them.wget command-line utility to download the bundles directly on to your CVM however chops down the signature files on the download links, this is due to the Download links being too long for wget command line utility.There is method to wget a release bundle from the Nutanix Support Portal directly to a CVM. In order to wget a release bundle on to a CVM/Host

The Nutanix platform and all products leverage the Security Configuration Management Automation (SCMA) framework to ensure that services are constantly inspected for variance to the security policy. Nutanix has implemented security configuration management automation (SCMA) to check multiple security entities for both Nutanix storage and AHV.  It continuously assesses and heals Nutanix clusters to ensure that it meets or exceeds all regulatory requirements. In this process over 1,700 security entities are analyzed and self-corrected across storage and hypervisor (AHV only) layers. Nutanix automatically reports log inconsistencies and reverts them to the baseline.With SCMA, you can schedule the Security Technical Implementation Guides (STIG) to run hourly, daily, weekly, or monthly. STIG has the lowest system priority within the virtual storage

 Networking on a Hyper-V host is very similar to networking on an AHV host and an ESXi host.  Naming of objects is again different, but functionality is the same: Just like with AHV and ESXi, the hypervisor has a connection to both the InternalSwitch and the ExternalSwitch.  The name of the hypervisor on a Hyper-V host is confusingly also Hyper-V, and this hypervisor attaches to virtual switches by way of a vEthernet port.  All virtual network adapte

I’m working on building a SQL Cluster on Nutanix using shared storage. Having issues on some of the steps in the ‘Creating a Windows Guest VM Failover Cluster’ walkthrough. (https://portal.nutanix.com/page/documents/details/?targetId=Advanced-Admin-AOS-v510:vmm-failover-cluster-create-t.html)   Have (not real values, used for example): SQL01A - 10.100.1.20 SQL01B - 10.100.1.21 Cluster Virtual IP - 10.100.1.10 iSCSI Data Services IP - Not set (blank) SQL01VGroup - Target IQN Prefix here   Status/Completed: I’ve already created a volume group with a few disks for testing. I have NOT attached it to the VMs yet. I’ve enabled MPIO on each of the 2 servers I’ve enabled iSCSI Devices in the Multipaths tab

So I recently asked this question…  https://next.nutanix.com/api-31/playbook-rest-api-post-teams-37756?postid=51764#post51764 I saw support for slack but no teams… I got to looking and sure enough API’s are available to call from within playbooks yipee!    Youll need to create an incoming web-hook in teams (google this if you dont have it setup).  open up a team channel, click connectors  select configure

We are looking to combine our two nutanix blocks together.we currently have the NX-3360-G6 and the NX-1365-G6. if this possible to achieve, do we have have to double up on the redundant connections per node? this would mean it would be occupying 12 sfp+ connections all together. can anybody shed some light or experience on this?

Dear Team, I purchased 3 node IBM Power node running with AOS.Once i am trying to create ticket with Nutanix they said raise ticket with IBM vendor but i couldn’t understand if the Issue with AHV then why i should log ticket with IBM?IBM vendor Only responsible for hardware issue.Please suggest anyone how to register the ticket IN kuwait region if customer having IBM power Node with nutanix native AHV.

Hi team,We have a 5 node SSD+NVMe cluster with RF3 and are considering adding 2 all-SSD nodes to that cluster.Are there any drawbacks/risks/restrictions to having only 2 nodes of all-SSD type in this RF3 cluster?SSD+NVMe nodes:  G7, 6256 CPU, 1TB RAM, 4x1,92TB SSD, 4x3,84TB NVMeAll-SSD nodes: G6, 6128 CPU, 768GB RAM, , 6x3,84TB SSD

Continuing on the previous post on all things snapshot. A few more questions today:What happens when I delete a snapshot? Do I loose data? R. You loose a recovery point but not the data, regardless, if it is the first snapshot, the snapshot in the middle or the last one in the snapshot tree. Let’s take a look at a few examples: A. You take a snapshot, create a file within the guest OS, take another snapshot and remove that file. Then you delete that snapshot. Whether that snapshot was in the middle of the chain or the first/last one, that file is no longer recoverable. B. You take a snapshot, create a file A, take another snapshot, create file B. You remove the first snapshot. File A is till there. You can no longer recover to the point in time where file had not existed yet however.If I recover a VM from a snapshot what happens if I then delete the snapshot?

​​​​​​Cluster lockdown is the ability to disable password based CVM access and/or only allow key based access to users.Nutanix recommends that access including SSH directly to CVM and hypervisor should be restricted to as few entities as possible. In high security settings, Cluster lockdown can be very appropriate and should be implemented Cluster Lockdown does not effect any cluster communication between its components. Cluster will function as normal.

Hi,Ｉ plan expanding cluster to add 3 nodes that model are XC640 and hypervisor is ESXi 6.7 U2.Cluster’s AOS versio is 5.10.6 LTS but additional node’s 5.16STS.I cannot add nodes...Can I anything to do additional nodes?And Do you know how to recreate CVM on new nodes?

 Ever wondered what are some of the main services/components that make up Nutanix?The following is a simplified view of the main Nutanix cluster components.All components run on multiple nodes in the cluster and depend on connectivity between their peers that also run the same component. Cluster components ZeusKey Role

We notice that after deleting VMs or Files the free space on Nutanix cluster doesn’t  increase instantly and may only reflect after a few hours.  This behavior of free space being slowly presented back to the cluster is expected behavior for Nutanix. The reason for this is because of the service responsible for cleaning up space, Curator. Curator takes time to perform scans on the cluster and spreads the storage across the disks and carefully removes the correct files (egroups) while maintaining redundancy for any data you want to keep. It takes a few curator scans before all expected free space is available again. Each curator scan is scheduled to be performed once per hour. To remove more da

Hello Community,Just, I want to know how can I setup a Solaris 11.4 or Solaris 11.3 VM on Nutanix, any guide or walkthrough?. Please, let us know how can we have this OS running on AHV. We have AOS 5.15 LTS.

Nutanix Move (Move) is a cross-hypervisor mobility solution to move VMs with minimal downtime. Move supports migration from the following sources to targets, where first platform being the source and second platform being the target.Starting with version 3.0 Move supports Hyper-V which means that you can now migrate consolidate your workloads from ESXi, AWS EC2 and Hyper-V on Nutanix and perform reverse migration in some cases. For a list of supported OS versions, Hyper-V versions, port requirements, useful commands and caveats be sure to check KB-6667 Hyper-V: Move | Basic understanding and troubleshooting.For all things Nutanix Move there is Move User Guid

If your cluster has no direct access to the internet, you can use the Dark Site LCM bundle, which you can put on a local web server and use it as a source for the LCM downloads.The web server can be a machine on the same Nutanix cluster that you want to upgrade or any other machine that the cluster will have access to. In this topic we will be creating a web server on a Linux machine and we will be using Apache Web Server. Note that this guide is for absolute beginners, so you will not need any prior experience. For this example, I have selected CentOS 7 as Linux distribution. If you want to use another distribution, the commands can be slightly different, so you will have to co

If your cluster has no direct access to the internet, you can use the Dark Site LCM bundle, which you can put on a local web server and use it as a source for the LCM downloads.The web server can be a virtual machine on the same Nutanix cluster that you want to upgrade or any other machine that the cluster will have access to. In this topic we will be creating a web server on a Windows machine and we will be using Microsoft IIS (Internet Information Services), so you will not need to download and install any third party software. Note that this guide is for absolute beginners, so you will not need any prior experience with this technology. 

Hi,I am exploring is there any Nutanix solution can like-for-like replace Riverbed Steelfusion solution?
