Cluster Shutdown, Node Maintenance Mode and VM export Automation

Hello Sirs! I just want to inquire and ask if anybody has an idea if Nutanix has a plan to automate the processes of doing a shutdown of the cluster, entering a Node to Maintenance Mode and exporting VM that resides to a nutanix cluster and integrate this basic operation to their Prism Element or Prism Central GUI just as what the other HCI vendors? currently I belive these things is done via CLI only. I know this is a easy task for a technical people and admin but I think it defies the "one click simplicity / one click operation" that is shown on presentation decks. It would be great and probably an additional edge if processes like this is automated. thanks 🙂

Powershell Script of detailed Protection Domain configuration

I have lots of Protection Domains. I need to keep their schedules straight, prevent overlap, and report the schedules to management. I am not the only admin, so I cannot track the configuration manually. Is there a powershell cmdlet that presents this information? I cannot find it. I want to know the schedule and the replication information(sites and how many to retain). I'm not using protection policies, just old school PD. Thanks, Bill Beavis

Script for Last Logon of Windows 7 VM?

Hi, I'm relatively new to Nutanix, so I'm still learning the concepts and terms. But I was wondering if it was possible to develop a Powershell script, for the purpose of getting the last logon of Windows 7 workstations running as VM's in our environment. The script would run from a central location on our network, so it would have to access AHV and then somehow be able to grab the last logon time in the guest OS by the user who "owns" the workstation. We determine who owns the virtual workstation, by determining the sole user listed in the Remote Desktop group. We can do this, in VMWware for Windows 10 workstations; but I've been told that it's a little more tricky to develop such a script for Windows 7 running on Nutanix. Any help or guidance would be greatly appreciated, so that I could get a starting point. Thanks.

a simple LCM question

I'm new to Nutanix, and have a basic question pertaining to keeping drivers and firmware in the server up to date with LCM. We have Dell XC640 servers running VMware ESXi. Am I too assume the LCM is going to provide all the drivers and firmware required for the stack? Documentation states that Dell provides the payload, LCM installs it. I want to validate after updating the hosts with LCM if that's all that I need to do. Does this also update the VMware Ethernet driver? It seems to good to be true that LCM would actually do that as well. Looking for some guidance on this so that I have a solid game plan that I can document moving forward.

VM's uptime get reset in vCenter after migrating the VM when we put host into maintenance mode from CVM's Putty Session

Recently i have upgraded some Firmware for one of the cluster. Firmware upgrade has migrated all VMs to other host and put the host into maintenance mode. i was cross checking the behavior on vcenter and found in tune as per process but after migrating all VMs to other host it reset the uptime for all migrated VMs in vcenter logs/view. but when checked guest os uptime then it was older than vcenter info. (VMs were not rebooted). i am unable to understand that, is it a bug or do i have an issue with Nutanix cluster.

Nutanix AsyncDR supports OEM hardware?

As the title stated, does someone know whether I can run AsynDR on OEM hardware just as Dell, Lenovo... or not? I have a customer wanting to create a AsyncDR session to backup files from a Nutanix cluster to a Nutanix on Dell servers. Is there any limitation so far? Thanks.

Create managed network with PowerShell

Hi All I've rather large number of non-managed and managed networks to create on multiple clusters and really am not willing to be creating them manually. I've created PowerShell script to create non managed networks, that was pretty easy. However, I'm finding it a bit more challenging to create managed networks using PowerShell commandlets. I understand that the command should look something like New-NTNXNetwork -Name "vLAN_Name" -VlanId "vLAN_ID" -ipconfig "IpConfigDTO" I can not find any samples of IpConfigDTO format. I understand that IPv4 default gateway address and subnet in CIDR notation should be provided as values but I can't work it out how. Any assistance would be much appreciated. Cheers

Nutanix Storage capacity and resiliency(three questions)

I have three questions. Please answer. 1.For example, we are using three nodes. There's a resiliency warning for prism because of the high utilization of storage. Then there was a problem in use and one node failed. I wonder what happens in this case. What kind of error is caused? Can we keep the service? 2.What's the maximum storage utilization that Nutanix can continue with its services? 3.What happens when storage utilization is 100%?

script to update categories and projects

I have a bunch of VM (>300) converted from vmware, and I have to classify them with categories and projects. I tried in powershell with the rest API, but when I GET the VM characteristics and use ConvertTo-Json to build new json file, it does not "expand" embedded arrays like disk_list, nic_list... so cannot send the PUT request correctly Does someone have an example to set/update categories and project for a VM ?

CVM Overheads

Could some one help me to understand how to calculate CVM overheads? I mean witout using the Sizer. I'm prety sure that some time before I have seen something about that in the documentation but now is removed. Nutanix bible sows some infor Drive Breakdown section but I'm not sure that it is up to date. So my question is how I can calculate overheads for the below: SSD: Nutanix Home Ext4 Formatting Genesis Cassandra OpLog Content Cache HDD Ext4 Formatting Genesis Curator

Running SSH commands on CVM via Ansible

Hello, Just wondering if there is anything special about running CVM commands via ansible or other non-interactive session tools? The ansible ping module works just fine but when I start using Nutanix specific commands i get errors telling me that "no such file exists." The commands i'm running are "cluster status" and "ncli rsyslog-config get-status" These obviously work in a regular interactive session but not with ansible. Am i missing a path variable declaration or something? Are the commands only available via interactive sessions(if that is even a thing)? Thanks Update: a coworker who is better at linux than I am said that the profile probably isn't loaded the same so I need to fully source all the commands. So right now I'm doing my best to find them and running them that way. So far so good. /home/nutanix/cluster/bin/cluster status

A dumb Question.. STS vs LTS

Besides the fact that LTS is Long Term Release and STS is Short Term Release, Is there any reason that STS shouldn't be used for production purposes over LTS ?I want to switch to 5.9 for the ESXi 6.7 compatibility.

[AHV] Nutanix cluster inventory and vm's , like RVtools , Portable no installation needed

I compile my code, now the user should not install anything .. just run and choose graphically where you want to record the report and the information looks much more orderly and complete. It is an extensive summary. 1) You just need to unzip the .zip and run the executable named NUTANIX_TOOLS_FOR_AHV_v1.7.9_PORTABLE.exe 2) A window opens where you must select where to save the report. 3) Once selected the software generates the report in the indicated place. If you want see a report example.

Getting started with Nutanix

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.

SR-IOV & Nutanix

Hi, I am currently working with a customer who is looking into Nutanix and we are planning a POC. They have large VMWARE environment running 6.7. They have some applications that require SR-IOV. If we decide to go to Acropolis, is SR-IOV supported in Acropolis or is there a feature similar to that available natively on Nutanix? Many thanks.

Redundancy Factor 3 and Replication Factor 2

Hi Together, How does the nutanix cluster handle failures with following settings: Cluster Redundancy Factor -> 3 Container Replication Factor -> 2 1) How many disks or nodes can fail? 2) Does this settings make sense or should the Container RF always set to 3 when Cluster RF is 3? Thanks for clarification! Kind Regard Steve
