How It works

Before you begin Before you decide to change the CVM, hypervisor host, and IPMI IP addresses, consider the possibility of incorporating the existing IP address schema into the new infrastructure by reconfiguring your routers and switches instead of Nutanix nodes and CVMs. If that is not possible and you must change the IP addresses of CVMs and hypervisor hosts, proceed with the procedure described in this document. Guest VM downtime is necessary for this change, because the Nutanix cluster must be in a stopped state. Therefore, plan the guest VM downtime accordingly. Verify if your cluster is using the network segmentation feature.nutanix@cvm$ network_segment_statusNote the following if you are using the network segmentation feature. The network segmentation feature enables the backplane network for CVMs in your cluster (eth2 interface). The backplane network is always a non-routable subnet and/or VLAN that is distinct from the one which is used by the external interfaces (eth0)

Can you imagine performing firmware upgrades manually?Checking compatibility matrix for each component, procuring ISOs and staging them, take days to perform firmware upgrade and one can only hope that the host/cluster is still functioning after everything is said and done.LCM simplifies Nutanix IT infrastructure life cycle operations by consolidating software and firmware component upgrades into a unified control plane. LCM does all the hard work of managing all the upgrade dependencies for the software and firmware components. You don't have to worry about a thing. LCM normalizes firmware upgrades across hardware platforms and provides a single unified process regardless of vendor. Based on the bundle of components -- software and firmware-- that are selected for upgrade, LCM creates a plan that ensures the updates are deployed with the minimal number of service or host restarts.Get Started: Use Prism Central or Prism Element to open LCM Perform the LCM inventory (default is set to

Did you know that many of the health checks and alerts within Prism can be configured according to alert policies?Though it is usually a good idea to leave alert configurations at their default values, some alerts (or checks) can be adjusted to accommodate particular needs through an associated alert policy. For example, if there is a known condition within an environment in which an associated alert goes purposefully and perpetually ignored or overlooked, the associated health check can simply be turned off.Alerts can also be enabled/disabled based upon a particular severity level (i.e. Info, Warning or Critical). Also, even better than outright disabling an alert or check, some alert policies can be configured for auto-resolution if the condition has not recurred within the proceeding 48 hours of its initial exhibition.More information regarding the configuration of checks and alerts can be found within the Configuring Health Checks section of the Prism Web Console Guide.

Hello everyone. I want to allocate IP to the cloned VM using sysprep through the blog address below.https://www.nutanix.dev/2020/02/06/customizing-ahv-vms/ However, the IP is not changed through the script in the blog.In addition, it was confirmed that the host name and password were changed. The versions I am testing are windows 10, windows server 2016. Please, let me know. Thanks,Regards

In AOS 5.0, you can expand the disk online. In versions older than AOS 5.0, you needed to go offline to expand the disk and then online again. But before expanding the disk you will need to increase the size of the volume group. The size the disk in a volume group can be increased using the Prism GUI or the aCLI or nCLI. This article describes the increasing the size of the volume group disk using nCLI and aCLI and also shows how to expand the disk online in Windows guest OS. Expand disk size of Volume Group through aCLI and nCLIFrom aCLI:Starting from AOS 5.x, the disk can be expanded without taking it offline.Increase the size of the disk:nutanix@cvm$ acli vg.disk_update <Volume Group name> <disk index> new_size=<size of disk>Note:  when specifying the size, uppercase G is for gibibyte, lowercase g is for gigabyte.From within aCLI, execute "help <command>" to get more information about commands, including optional arguments. From nCLI:Increase the size of the

I was writing a quick PowerShell script this morning and I wanted to get all of the VMs in Prism Central via the v3 API calls. I was struggling with the syntax until I found this post:v3 - vms/list - Host to get full list of VMs? The post lead me to this article:The Five Hundred (500+ VMs via v3 API) The article lead me to this code sample:list_vm_v3_large.py After reading those articles a few times I still didn’t understand what I needed to do...I finally figured it out. I could piece together the v3 API call, but I couldn’t get the correct number of VMs to return. After hitting the wall a few times I figured out the part I didn’t understand: the relationship between length and offset.Here is what you need to understand:The “api/nutanix/v3/vms/list” v3 API command method is POST. That means you must include “body” in your API call To get the total number of VMs you can use this JSON: {"kind":"vm"} Note: This will give you the total number of VMs in the cluster/PC. The results will loo

Do you know you can run a individual log collector just for LCM logs if you are having any troubles running updates from LCM?LCM (Life Cycle Manager) Log Collection Utility provides an independent script designed to collect all the important log files necessary to debug any LCM issue.The utility is available in LCM version 2.2 or later by default. It could also be used on earlier versions of LCM.Functionality:Collects LCM log files. Detects if the node is stuck in Phoenix and collects kernel logs. Collects logs for the services with which LCM interacts (Example: Foundation, Prism, etc.). The utility state is independent of such of the LCM hence it is capable of collecting logs even if the framework is down. Parses LCM configurations from Zookeeper nodes.Files/Info being collected:Node Level Information LCM leader Foundation version LCM version Hypervisor type/version LCM configuration /etc/nutanix/hardware_config.jsonFor LCM 2.3.1 and later (Automatic log collection)LCM 2.3.1 automatic

Nutanix customers using AHV as their Hypervisor often need to evaluate resources being used/consumed on their infrastructure.  One of those factors involved is in calculating how much space has been consumed by one or more Virtual Machines.  It is possible to get granular in this scenario and be able to calculate the amount of space taken up by a VM.  Depending on their environment, it should be possible or feasible for one to print out the space usage in terms of Bytes, KiloBytes, MegaBytes or GigaBytes.I have developed the following string manipulation to be able to get those numbers.  Here is a sample from one of the checks I performed:nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$ acli vm.list | grep 120-Windows-Invent120-Windows-Invent 99021293-4ea5-440a-a894-846ed07de132nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$ acli vm.get 120-Windows-Invent | grep vmdisk_size | awk '

What is Fault Tolerance (FT)?FT is how the system ensures that both user VM data and cluster infrastructure data is protected from failure. What are Fault Domains?Failure scenarios can be thought of in terms of fault domains.  There are four fault domains in a Nutanix cluster:Disk Node Block RackThis article focusses on Rack Awareness. Rack failure can occur in the following situations:All power supplies fail within a rack Top-of-rack (TOR) switch fails Network partition; where one of the racks becomes inaccessible from other racksWhen rack fault tolerance is enabled, the cluster has rack awareness and the guest VMs can continue to run with failure of one rack (RF2) or two racks (RF3). The redundant copies of guest VM data and metadata exist on other racks when one rack fails.Note – Rack fault tolerance has to be configured manually. Requirements and configuration of Rack Fault Tolerance can be found here.To learn more about Rack Fault tolerance on Nutanix Clusters click here.Now, Rack
