Issues with installing Nutanix Community Edition on a Bare metal HP server for a LAB

I would like to ask for some help on identifying why I receive below error prior to installing Nutanix Community Edition on a HPE Gen9 Server. We want to install Nutanix Community v2.0 for some LAB testing on a single 1U server.Steps we have taken for the install.1. I have created a bootable disk on a USB with version: phoenix-ce2.0-fraser-6.5.2-stable-fnd-5.3.4-x86_642. After boot all looks OK and we are configuring the disks as below: Attached is "Disk_config.PNG" - This is what we have as a Disk. Only C is SSD. The 16GB is the Install Media.3. I accept the EULA and scroll to the bottom4. Here is where the issue appears. We receive an ERROR Please supply 'Serial Number'. I have checked in NEXT and online but no luck..5. When I hit Enter it goes back to EULA.I was able to install the same way when I do it on ESXI, but on bare metal it looks like we are failing some king of S/N check..

Networking issues - trying to add in a second switch

Hi AllHavoc struck this morning when I tried to move my AHV cluster from old switch stack to new switch stack - the hosts, I think went into panic mode and started to restart various VMs.The background to this is: I have 2 x Dell X4012 core switches and 2 x Dell N3024 ToR switches, currently due to moving VMware environment to Nutanix only 1 x X4012 is connected to NIC 1 on each of the 3 hosts. From the X4012 there is a cross connect into the old VMware network Core blade switches (Dell 8024 x 2) which are connected to the old ToR N3048 switch stack, these are then connected to the router for VPLS and DMZ. So to move the connectivity, I thought I could add the second NICs of the hosts to the second X4012 and disconect the crossconnect and the first NICs thus using the newer switches, albeit on the opposite NICs. I planned to reconfigure and update the first X4012 and add back into the stack with a LAG to the N3024 stack and no crossconnect. I moved the NIC connections and lost all

Turning off deduplication

Hello,We used compression and deduplication for a while but now it is not necessary.I disabled these functions in the storage settings but the cluster is still showing the dedup space savings with no changes. This is after a week or so of turning dedupe off.I can’t find any documentation around disabling dedupe and what is required to ‘unoptimize’ the data.I’m using AOS 5:15.5.1 LTS and this is an old NX-1050 3 node system.TIA

AOS (ESXi) and ROBO licensing model

Dear All,I’ve have a question about a licensing of the AOS (ROBO per per VM).Environment: vSphere7 (vCenter7 + 2-node ESXi clusters). Basically, fresh Nutanix cluster with HA feature enabled is hosting x4 “service” Virtual Machine:* x2 CVMs, x2 vCLS ( https://kb.vmware.com/s/article/80472 )As far I understand CVMs don’t need to be covered by the ROBO license, but what about a vCLS? How AOS is qualifies vCLS: as a service or a “standard” VM?Also, do I need ROBO license for the powered-off VMs?Regards,Dominik

Build new cluster vs. expand existing cluster

Hi All,We currently have an 1 Block, 3-node cluster (NX-1065-G5) with approximately 50 VMs on it. It is approaching end of life, and we are replacing it with another 1 Block, 3-node unit (NX-1065N-G8). At end-state all of the VMs will be on the new hardware, and the old hardware will be powered down.Would we be better to…Build the new unit as a brand new cluster, and move all the VMs to it using Nutanix Move. Expand the existing cluster by adding the new hardware to it, and then remove the old hardware from the cluster. Has anyone gone through either of these processes?Thank you for your suggestions.Marlon M.

How to restart a hypervisor upgrade after aborting

Can someone let me know how I restart the upgrade on the failed host? I cannot seem to find any restart/retry button.The host failed to go into maintenance mode and now upgrade says aborted on this one host.I have fixed the cause of maintenance mode now so it will be fine.

What's the performance impact if we change RF from 2 to 3?

Dears:We have a 3 node pure NVME SSD clusters with RF 2. Now we plan to expand more 5 nodes and change the RF from 2 to 3. We have a little worried about the performance on :(1). During conversion phase from 2 copies to 3 copies.(2). For BAU usage, if RF3 performance will slower than RF2 because every write need do 3 times compared of 2 times. I got the question 1 answer from Nutanix Resiliency – Part 2 – Converting from RF2 to RF3 | CloudXC (joshodgers.com) and want to see any more experience. For question 2, any experiences could be shared? Thank you very much! P.S. We have enabled compression feature.

CE-2020.09.16 Kernel Version

I have figured out that the version of the kernel is 4.19.100. I have also figured out that this version is not working with my NUC11 and the i225-V NIC. I would like to replace that kernel with the 5.15 kernel as the 5.15 kernel works with the i225-V NIC. Does anyone have a procedure on how to replace the kernel in the ISO? Any help would be greatly appreciated. Thanks,Steve

How configure vLAN native on vLAN10?

Hello everyone,I have to install the first Nutanix cluster from a customer but I can't figure out how to setup the network.All customer switches (Aruba 2930, 2920) have the native vLAN (vLan1) dedicated to workstations and servers, while the management network is vLan ID 10 where the ESX, storage controllers, backup NAS and the Veeam server backing up the current infrastructure.This is the situation of all my customers, vLAN10 is completely isolated and unreachable from the native vLAN1, this was done to prevent any ransomware from affecting the backups as well.Now, Nutanix recommends configuring the CVM and hypervisor host VLAN as the native, or untagged, VLAN on the connected switch ports.I'm sure it would be nice to have all of the management in the native, adding a node would be much easier and I think the simpler things are kept the better.Furthermore, vLAN10 is propagated on many remote racks because obviously the backup NAS do not reside in the same racks as the servers, how can

Automatically power on VMs at cluster startup

In VMware, there’s the option to automatically power on VMs as the cluster is started. Is there such an option in Prism or do you have to rely on a script?

Accounts for security scans

Hi, I’m new to Nutanix, coming from the vSphere world.I am working on getting our new Nutanix infrastructure set up to run Qualys scans for security. I have been looking at the following document:https://portal.nutanix.com/page/documents/kbs/details?targetId=kA07V000000LXYqSAOI am getting stuck at determining which accounts to use to set up authentication, so that Qualys can run its scans on the Hypervisors, CVMs, and Prism Central appliances. My research shows that adding new accounts via the OS to these components is not supported. Does that mean that Qualys then has to log in as root, nutanix, and admin respectively, to scan these components? Or am I looking in the wrong place for the Qualys account to be set up, to scan for vulnerabilities and compliance? I feel like I'm missing something here. Thanks!

Can't install NX G6 AOS 5.10 version?

The NX G6 demo equipment is currently updated with the latest firmware. If you try to install version 5.10 to test the AOS upgrade with the latest version of the foundation, the 4. foundation version will not mount, and the 5. latest foundation version will not configure CVM after rebooting after installation and installation will fail. Is it like this originally?

Can't install the lower version of AOS?

There are still many places where the old version is being used.Even if you try to install it with the previous version (AOS 5.10 or lower version) of the foundation on the G6 device to test the upgrade, it cannot be installed.Is it because all the firmware is up to date? It was the version that was originally installed. AOS 5.10 versions are not installed now?In foundation the log is "Device 2 :The Length of Name is not correct" The phrase continues to print. Please reply from those with experience.

Replacing upcoming EOL hardware process

My 3 node cluster consiting of 1065-G5 nodes is coming EOL this year. I will be replacing the hardware with a NX-3360N-G8 cluster. What is the recommended workflow for replacing the hardware? One thing to note is the current cluster is licensed with Prism Pro and the new one will be licensed with Starter as I’m not using all the features in Prism Pro.Is the replacement as easy as expanding the cluster one node at a time, migrating the workloads and then removing the old cluster? Will there be any hiccups with difference in licensing?
