Prism Element PD: Compare VM size before/after replication between clusters

I configured domain protections between my primary and secondary site.domain protections are configured by VMs which means that I have as many domain protections as VMs.After the first replications, I would like to make sure that the size of my VM on the primary site is identical on the secondary site but I find that this is not the case.I don't know if I'm doing a good interpretation.Attached is the capture of my VM on the primary site before replication and on the secondary after replication.Please help me with your explanations.

NGT Compatibility for Rocky Linux

Is there an ETA for when NGT will add Rocky Linux support? This Reddit thread from August 2021 is the only reference I could find online suggesting that Rocky NGT support was being worked on. The NGT compatibility matrix lists Rocky as one of the OS vendors, but there are no approved OS yet.   Alma Linux (the other RHEL clone project) is already listed in the compatibility matrix, so I assume the delay in adding Rocky is not a technical one. Here’s what happens if I try to install NGT on a Rocky VM:rootin nutanixngt/installer/linux via 🐍 v3.6.8                                                              ➜ ./setup_python.sh -hPlatform type is: x86_64Unsupported distribution : rocky linuxERROR: Failed to install Nutanix Guest Tools.

Nutanix same CVM vlan on two separated Clusters

hello, I have a Nutanix cluster with 4 nodes and AHV running in my environment, but due to another project we will configure a new cluster with 4 nodes and AHV in the same network but for another purpose, I had a question, can I use the same CVM vlan of the existing cluster for the new cluster?

Move Cluster To Full-flash To Hybrid Mode

Hello Team,Is it possible to transform a full-flash cluster to an hybrid one without losing data? (third party platform).Licenses should not be upgraded because SSD space would not change but the necessary SAS disks would be added to add extra cold data space

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..

vCenter connection failed to establish

I’m testing Nutanix on an old server (1065-G5 generation). The connection between Prism and vCenter is registered, but not established.  I’m using AOS 5.20.4, ESX 7.0.3, NCC 4.5.0.2. The port 80 is opened and redirected to HTTPS. What could be the cause?

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

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.

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

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!

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?
