Adding a G6 node to existing G5 block

Hi All, Is it possible that we add a G6 node to an existing Nutanix Block running 3 1065-G5 nodes? or we will have to add another Nutanix block containing a single G6 node and make it part of the existing cluster?

SSH access to CVM and AHV to check on the security settings enforcement

Dear contributors, We have purchased Nutanix appliances and I am working as part of the IT Security team. We have enforced the security settings on CVM and AHV (STIG, banner, ...) and, as part of our duties, we carry out regular checks to make sure that the security settings have not been altered. For this, we would like to have nominative accounts which are able to connect through SSH and be able to check on the settings of the components. Is it possible to do? If yes, how can we proceed? Thank you in advance for your assistance.

Is different Hypervisor support Nutanix cluster?

Hello All, I’m quite new to nutanix, I have a question: Can we add three different hypervisor nodes in a single Nutanix cluster. ex:- if we have three nodes with below hypervisor Node 1 - Esxi Node 2 - AHV Node 3 - Hyper-v So can we add these three servers in nutanix cluster??

How CVM & Hypervisor get installed on a Node?

What if we are adding a new Node to our existing Cluster, how we get Hypervisor(ESXi) and CVM(AOS) get configured so that it's visible in Prism Console for expansion.

AFS - Home directory permissions allow ALL users to read ALL home folders?

We just set up AFS. On the home directories, we expected that like a Windows home directory setup, the user would be the only person able to view their home folder. (and Domain Admins of course). But, on AFS per this doc https://portal.nutanix.com/#/page/docs/details?targetId=Acropolis-File-Services-Guide-v20:Acropolis-File-Services-Guide-v20 and also per our experience it seems like ALL USERS can view everybody's folder and contents. This seems like a security problem since HOME directories are typically expected to allow only the user to view their data. Is this by design? It seems like a significant security challenge and much different from how this would typically be set up on a Windows file server.

Foundation 4.3 VM OVF/VMDK Files?

Looks like the Foundation VM OVF/VMDK files are no longer available from Portal > Downloads > Foundation. Anyone know where they are hosted now? I have a remote bare metal installation scheduled and I'm dead in the water. Even the Foundation 4.3 Field Installation Manual released less than a month ago still references downloading the VM OVF/VMDK files from the portal where they don't seem to exist anymore.

[Figured Out] sFTP Unable to connect - Access Denied. Using WinSCP & FileZilla

Hello. I am trying to connect to the /iso/ folder to clean up some of the old versions. I also connected some VMware Datastores that I should probably do some housekeeping as well. I connect to the cluster primary IP 192.168.1.100 and get access denied. It's the same nutanix username & password I use for SSH which works fine. https:// I updated firewalls to allow port 2222 (thanks @sandeepmp ) but still getting access denied which makes me think either 1) nutanix and root won't work and/or 2) the folders have different credentials than ssh. ********************************* SO after typing all that, I realized I was supposed to use the login administrator to the web nutanix portal (admin). Oh geez. Well, I'll leave this all here in case somebody wants to do a dumb like I just did.

Repost:Communication trouble of CVM when building CE on Nested ESXi

# On March 4, I posted the following but I have written the wrong answer myself, and the status of that bank has become "solved". # Actually it remains unresolved.

Containers

Would I be able to create storage containers in my cluster for the purpose of "pinning" VMs only to hosts that are assigned to the containers - restricting VMs to the hosts that belong to the container? The need is to control VM migration during Software Upgrades due to multicasting issues with the hosts.

Guidance on Sockets, Cores, Logical Processors

Hello again CE community! I'm running a Dell R730 with these specs: 2 Sockets 8 Cores Each Socket 256 GB RAM I'm running ESXi to run a 4-node cluster and want to parcel the CPU and Memory evenly among the 4 CVMs. Q1: Based on this, what should my CVM CPU/RAM settings be? Q2: When I allocate vCPU and RAM for VMs, how do I translate a bare-metal config spec e.g. 4x WS2016 8 CPU, 32 GB RAMto Nutanix VM specs, based on these constraints? I just need an example to shine light on how to break down the physical to esxi to nutanix CVM to VM specs. Thanks in advance, Brit

Layer2 Issue - AOS 5.5.8 - AHV

I have a problem with arp requests on the bridge for guest traffic In the drawing below the current architecture. If a request arrives from the outside, passing through the firewall, and the firewall is starting to communicate to a VM connected to a NIC to BR1-UP bond of BR1 bridge, the ARP request for the resolution of the VM address stops at the bridge BR1 and do not reach the VM, in this case the firewall and VM ARP tables remain unpopulated and the communications stop. On the other hand, if the communications depart from the VM to the Firewall (for example with a ping) the ARP request is processed by the firewall and the ARP tables of firewall and VM are correctly populated with the respective MAC ADDRs. Firewall IP and VM IP are in the same broadcast domain, no routing. I checked with Wireshark on the windows VM, with tcpdump and ovs-appctl fdb/show on the Nutanix host and when the communications start from the firewall the ARP request goes up to the physical card of the BR1

I've inherited a Nutanix setup. I've noticed there is 1 Storage Pool setup and 4 Storage Containers. (see screenshot).  I don't know what is the Default setup looked like so I don't know which are required. I'd like to have 1 container. Currently attached to Nutanix Host VDI_POC nutanix-peristent-pool Not attached NutanixManagementShare SelfServiceContainer All of my VMs are on the VDI_POC. Can I somehow delete the other 3 and combine them into the VDI_POC without losing data/downtime?

DR Scenario

We have a scenario in which we are running VMware vSphere environment on existing servers and planning to deploy a DR site. Is it possible that we deploy a Nutanix AHV environment at the DR site and replicate from the existing ESXi environment at the Production site to the Nutanix DR site somehow? We are currently using Veeam backup and replication for VMware for backup. What is the possibility of such a requirement?

Nutanix CE installation issue.

Hi All, I did use Nutanix CE on a standalone server before for testing and for backup recovery test. Today I was trying to install the new CE version ce-2018.05.01-Stable. The previous version I used was CE0-2017.05.22-Stable. Now the hardware is same. 1x 240 GB SSD, 2x 500 GB HDD, 3x 1TB HDD. 128 GB RAM Boot from USB. 3x 1 TB drives are in Raid0 - Storage 2x 500 GB drives are in Raid0 - ISO's 1x 240 GB drive is in Raid0 - OS - (I tried this with Raid and with out raid.) this time when it is checking the disks it says "MinimumRequirementsError: A set of disks matching the minimum requirements was not found" is there any changes to the minimum hardware requirements with new version of CE? Please help me with this. Thank you, Krishna

Prism Central monkey always happy

I just upgraded our Prism Central to version 5.7.1 and noticed that the widget with the banana-holding monkey never changes when we get an alert from one of our managed clusters. I removed and re-added the widget from the PC console but it still never updates when we receive an new alert. Grated, this is not very important but has anyone else seen this issue?

HyperV 2012 R2 Migration to AHV

Hi, We have a Windows 2012R2 HyperV host with about 8 Windows 2008R2 VMs. These VMs are Gen1 using .vhdx as the file system. I'm currently running Ntnx 4.7.4 and was wondering the following: Does the image service import .vhdx files or do I need to use qemu-image ? If I use something like Starwind V2V converter, it supports QCOW2 and RAW, is there a preferred Ntnx format ? (Image inserted below) Does the SMB version on the CVM have unique specifications ? I was trying to use Storagecraft Shadowprotect Recovery options (Linux based) but it would see the UNC?Thanks in Advance, G [img]https://uploads-us-west-2.insided.com/nutanix-us/attachment/2506iD6764FB6092E7F6F.png[/img]
