Deployment Success

Hi there, I am new with Nutanix and I have a doubt about Acropolis licensing. We have 3 nutanix nodes with Acropolis Start Edition installed. Yesterday, my PRISM console report a License Feature Violation. Looking at https://www.nutanix.com/products/software-options , the only thing that I saw that could be wrong in my configuration was a Volume Group created for a test. Just to be sure, in an Acropolis Start Edition can we create volume groups or this option should only be used in PRO and ULTIMATE editions? The alert don’t give me more information about which feature is violating the license. Thanks in advance for the help! BR, Thelmo    

Let's say that you have purchased a new node and you wish to make it part of your existing cluster, how would you do that?   A cluster is a collection of nodes. You can add new nodes to a cluster at any time after physically installing and connecting them to the network on the same subnet as the cluster. The cluster expansion process compares the AOS version on the existing and new nodes and performs any upgrades necessary for all nodes to have the same AOS version.   The process for adding a node varies depending on the AOS version, hypervisor type (AHV, ESXi, Hyper-V, or Citrix Hypervisor), data-at-rest encryption status, and certain hardware configuration factors.   Here is the guide to expand a cluster that explains the expansion process and the pre & post checks:

Let’s say you run the NCC health check in your cluster from a cvm and it's clean, other than this one INFO check regarding default_password_check.  Running : health_checks system_checks default_password_check[==================================================] 100%/health_checks/system_checks/default_password_check [ INFO ]------------------------------------------------------------------------+Detailed information for default_password_check:Node x.x.x.x:INFO: One or more IPMI devices are still using the default passwordRefer to KB 6153 (http://portal.nutanix.com/kb/6153) for details on default_password_check or Recheck with: ncc health_checks system_checks default_password_check+-----------------------+| State | Count |+-----------------------+| Info | 1 || Total Plugins | 1 |+-----------------------+

Let’s take a moment here to accept that we all have had questions regarding the AOS or Hypervisor versions in the cluster and the node to be added during Cluster expansion. These questions arise if the new node is imaged before adding it to the cluster.   For us, we can say, “With great expansions, comes not so great dependencies”   There can be 3 common scenarios:- Same AOS and Hypervisor version:- All good, no action required... The node is just a click away from the cluster. AOS is same, Hypervisor is different:-

Hello everyone, I'm having problems with the cd-rom assembly in all my VMs, I can't add it with an * .ISO image, and I can't remove or disassemble the existing cd-rom, can someone help.

We are about to buy and 4 node box with 8*16 core processors.  On top we are going to utilize AHV Here we are going to run 2 or 3 Microsoft Operating system only Now what version of microsoft license we need to buy?

In our environment we are currently hosting 2 HP Gen9 ESXi servers. Our plan is to purchase a single HP Gen 10 and having a 3 node cluster made out of it. To start with I want to create a single node (Gen 10) and slowly start moving VM’s from the esx host to that Nutanix host without interrupting the 2 esx servers. So my question here is, How is it possible for me to start with a Single host and start adding hosts to make up a cluster of 3 nodes (1 → Gen10, 2-Gen9)?

Let's say that you decided to adopt the Container Deployment approach by deploying a Kubernetes cluster, here is a brief explanation about Kubernetes and it's integration with Nutanix. Karbon orchestrates Kubernetes clusters to simplify the provisioning and management of containerized applications. Kubernetes packages applications in their own dedicated containers together with all of the required operational components for running the application. Containers , which run inside of pods on top of nodes, are the core building block of Kubernetes architecture. Containerized applications are simple to manage, easy to deploy, and portable as they are abstracted from the OS of the host. Since different containers share an operational kernel, they do not require as much compute capacity as a VM, making them "lightweight". Usin

Let’s say you need to increase the CVM memory depending on the workload or to enable certain AOS features. You can increase memory reserved for each Controller VM in your cluster by using the 1-click Controller VM Memory Upgrade available from the Prism web console.   To increase the memory, follow these steps:- Login into the Prism console. Click on the gear icon. Select “Configure CVM”. Select

Hello, I am looking for a link to find all versions of Nutanix products. Thanks for your help

What if one day you wake up and decided to give AHV a shot? But wait… you are running ESXi.  Hmm… If only there was a way to convert ESXi to AHV. Well… there is a feature called “In-place hypervisor conversion” to save the day.   But what about the VMs?  All the VMs that are running in the ESXi cluster are converted so that they can run on the AHV cluster.    Following are the enhancements to this feature are:- Decreased VM downtime. The state of the VM is preserved and the VM is brought

Receiving emails about EOL, but no clue what it means? Once a product is EOL (end of life), then there will be no further upgrades/updates released for it and will no longer be supported by Nutanix.   This may include the AOS version, Prism central, Nutanix files or Supported hardware platforms.   To view the EOL information, navigate as follows:-   Login into Nutanix Support Portal. Menu > Documentation. EOL Information

So you are planning to configure VM-VM anti-affinity policy in your AHV environment to ensure critical VMs run on different hosts. That’s thoughtful thinking right there and it makes sense.   Now if you create this policy when the VMs are off... when you power them on, you’ll see the policy kick in and the VMs will be running on different hosts.   But… what if the VMs were powered on when you applied the policy? Do you have to restart the VMs?   The answer is No.   After the policy is created, Acropolis Dynamic Scheduling  (ADS) will migrate the VMs running on the same hosts to dif

Working using CLI is easy, simple, elegant and fast. Every administrator loves scripting and automating tasks using the command line. Nutanix makes Management tasks related to virtual disks easy, simple and efficient using CLI. So, what are the situations in which you might need to perform VM Disk management actions if you’re an administrator? You created a VM with a disk of 250GiB and now you need to increase it to 500GiB What if you need to increase the size of a VM Disk? Created a Disk but now need to clone it to different VMs! Need to create an image from a VM disk?

Hi Guys,   i have some questions, first, can we enable flow on ESX hypervisor on nutanix? i have same question with calm on esxi and i get the answer we can enable calm on esx based on nutanix KB, but how about flow? can we enable/using flow on top esx hypervisor?  and just courious, anyone have table comparation about feature nutanix running on ahv, esx, hyperv?

Hi, NCC is reporting that I’m missing the cpupower command. Seems strange. I’m using a i7-2600k processor in each node. Should I install the package using yum repositories?  Where does it run, host or CVM?   Detailed information for host_cpu_frequency_check: Node 192.168.0.127: ERR : Error while getting host CPU frequency range. bash: cpupower: command not found   Node 192.168.0.121: ERR : Error while getting host CPU frequency range. bash: cpupower: command not found   Node 192.168.0.125: ERR : Error while getting host CPU frequency range. bash: cpupower: command not found   Node 192.168.0.123: ERR : Error while getting host CPU frequency range. bash: cpupower: command not found

Let's say that you upgraded your cluster and noticed that the timezone of your AHV has changed, why and what is the recommended practice?  When running a health check, you will see a warning stating that "The AHV host's time zone was changed/set to something other than UTC." Nutanix recommends against making any configuration changes on the AHV hosts which includes changing timezone, from AHV version 20170830.58, the default timezone on AHV hosts is set to UTC upon upgrade or installation, for more information check out KB-6834 In this case, no further action is required from your side. To edit the timezone of a user VM, check out KB-3134 To edit the timezone of a CVM, check out 

Ever thought a lot about advantages of UEFI over legacy BIOS? No? Who does that anyway?   To start with, UEFI firmware is a successor to legacy BIOS firmware that supports larger hard drives, faster boot time and provides more security features. Creating and starting VMs with UEFI firmware provides the following advantages. Faster boot time Avoid legacy option ROM address constraints Include robust reliability and fault management Use UEFI drivers

Howdy,   I’ve searched through all corners of the web, but still didn’t find a clear answer to this question: can Nutanix prioritize packets and/or traffic in OVS? And, if yes, is there some online how-to that I can refer to to learn how to do that?   Thanks in advance,

Howdy, I already know that Debian is an unsupported Linux distribution for using NGT on. But I still *must* try NGT on it... how can I force the instalation of NGT on Debian?

Let's say that you are monitoring your cluster's performance or you received alerts regarding high CPU on a CVM.  Why high CPU utilisation on a CVM is a critical alert?  The CVMs are one of the most important components in a Nutanix cluster. It is crucial that CVMs are healthy and perform their tasks properly as they run Nutanix software and serve all of the I/O operations to the hypervisor and all VMs running on that host. To understand the reason behind the high utilization, begin by identifying patterns of the performance:  Is the high CPU constant or periodic?  How long has the high CPU been occurring?  Is there a similar behaviour on other CVMs?  Certain patterns may point towards a cause. For example, a periodic spike may be attributed to antivirus, backup or a similar scheduled task being run in the background. T

Can someone help me with a power shell script which can help us to build multiple VMs by using a Win10 template we have. The environment that I am trying to build the VDIs have Nutanix as the Hardware and ESX 6.5 as the Hypervisor. The script should able to build the machines with sequential number and put them under a specif folder in Hypervisor. I can get the different templates for different containers and with proper Vlan.
