Can Nutanix configure IPv6 addresses?
Hi, I have questions.We are considering whether it can be operated with IPv6 in our IT infrastructure.So,I found that the prism element can be configured with an IPv6 address. However, I didn't know if components such as Prism central support it. Can Nutanix configure IPv6 addresses? Does Nutanix support IPv6?
Phoenix failed to run on G3 platform
I have an old G3 block that need to be installed for a demo.And after lots of failed tries from Foundation installation, I ended up installing the node manually. But unluckily after creating phoenix iso file for AOS installation and mounting it to the node, an error occurred with message below:“Unable to match system information to layout module”Has someone seen this happened before?
CCTV onto SSD instead of HDD
Hello Nutanix CommunityI have a VM that is running CCTV operations. I record multiple video streams in a high resolution and frame rate. Old files get deleted when the space is used up. How can I make sure that the SSDs are not being used for the recording to avoid them to get too many write cycles too fast?Kind regards,Ibinema

Ubuntu Cloud on AHV
Ubuntu Cloud Images are pre-installed disk images that are customized by Ubuntu engineering to provide Ubuntu Certified Images, Openstack, LXD, and other features in public cloud environments.Due to the pre-built image and customization the OS requires specific virtual hardware such as a serial port that AHV does not include by default. When trying to boot a VM on AHV from any of the Ubuntu Cloud images, the boot process stalls after loading the Btrfs module as the hardware is not there.This can be helped by customizing the VM manually using a combination of Prism and aCLI commands or by leveraging API calls.Download Ubuntu cloud image in .img format Upload as Disk to Prism Image Services Create a new VM and attach the disk created in step 2 as Type: "Disk", Operation: "Clone from Image Service", Bus: "SCSI" and for Image select the name of the uploaded image and then click "Add" Select "Custom Script" at bottom of the window (AOS 5.10.6 and later) and in "Type Or Paste Script" paste t

assign gpu on vm
When you open the console window after assigning the GPU to the vm as Passthrough and turning it on, "guest has not initialized the display" appears.When changing to uefi -> bios legacy, the console screen is displayed. What is the difference and is there a way to do it in uefi environment?
vCenter 7 U1 support
We are currently on vCenter 6.7U3j and looking on my possible upgrade path to vCenter 7 I need to go straight to 7 U1.https://kb.vmware.com/s/article/67077#vCenterServer6.7to7.0Should I wait for 7 U1 support or can I expect Prism/Nutanix and Nutanix Move to play nice with vCenter 7 U1?Looking at release notes for Nutanix Move I see only vCenter 7 for example.https://portal.nutanix.com/page/documents/details?targetId=Release-Notes-Nutanix-Move-v3_6_2:Release-Notes-Nutanix-Move-v3_6_2
Scheduling NCC Health Checks
Many users try to periodically execute the NCC health checks as a good offensive tactic against any issues that might appear within their cluster, which is a great idea! However, rather than writing that down as a reminder somewhere or simply trying to remember to do so, many do not realize that this task can be scheduled right from within Prism.The task can be configured to execute as per the following schedules: Every 4 hours Every Day Every Week When choosing the every day or week options, you are also presented options to configure the execution according to a specific time of the day and specific days of the week respectively.What happens with the results when the scheduled NCC checks are executed? An email is sent to the email recipients configured within the Alert Email Configuration settings of the cluster.For more information, including the specific procedures for configuring this feature, please refer to the Scheduling and Automatically Emailing NCC Results section of the

Prism Central Focus
Hello All,I have successfully installed Prism Central and it has been working well. I have configured a “view” under the focus button in the vm’s menu; however, this setting will not stay once I log out and back in. Currently the process is once I log back in I need to click on focus and pick my view. Is there a way to make that my default view? Maybe tie the view to my user account? I have included and image below to help. Thanks,Scott
Two Subnets in the same native vLAN
I have a setup with two subnets in the (same) native vLAN. The first subnet is (kind of) forced on me by Unifi (router, switch, APs in in the native vLAN) and I created the second subnet for Nutanix (recommendation ist only Nutanix devices/VMs in the same subnet). Now I need a router or routes configuration in the Nutanix subnet to get access to the other subnet and the internet. What do you suggest to achieve this in a simple way or what is the recommended way of doing that?

Manual cluster create fails after host remove.
Hello, All.Good day!! I have an issue and need your help and advice. 1. using 10 nodes, but I want to configure 2 clusters with 5 nodes each. (Composed of RF3) 2.

Is there a script or tool for clearing down the home directory?
Hi, I often get the error of: Warning : Disk space usage for /home on Controller VM... Does anyone have a definitive list of what needs to be deleted beyond the installation files? or a script that deletes the un-needed files? Surely it is something Nutanix should be building in to the system, I never have problems with VMware running out of installation space! Thanks Eric
Is there a detailed HCL?
Hi all!I’m looking for a HCL that details the exact firmware versions of specific components of a server to make sure that we are in the clear before we install or upgrade Nutanix.As far as I can tell there isn’t anyone to be found, at least not for someone who doesn’t have an account for the support portal (and I find it pretty odd to “hide” the HCL).I know there are HCL’s to be found outside of the support portal but those are extremely generic.Is there an HCL that is this detailed or is it only through trial and error we can figure out if we have the correct firmware?Thanks.
Generate Crash Dump Files for Linux Guest VMs
There are times when working with your environment that one of the Linux guest servers will go unresponsive. Nutanix Support may ask for crash dump files from the Linux VM to further analyze the cause.One such method is to use “sysrq”. This utility found on the Linux Guest OS allows access to several essential kernel commands and allow Nutanix Support to take a more holistic approach in trying to find a root cause.NOTE: If the VM is hung/inaccessible and "sysrq" has not already been activated, you may not be able to generate a core dump with the following method. You can configure the "sysrq" when VM is up and running and wait for the future occurrence.For more information on how to activate this feature, take a look at the KB 9066 on the Support Portal
