Currently I building the following versions: AHV ver,10.0.1  AOS ver,7.0.1DNS is configured on the CVM but it seems that the DNS settings are not synced on the AHV.I confirmed that the DNS settings were entered from Prism Element as well.Re-entering the DNS values ​​did not fix the issue.If anyone knows the solution, please tell me

New CE cluster stuck on creating cluster

Hi Nutanix-Community, trying to create a Nutanix CE cluster with 4 nodes out of our old hardware. This are the specs of the nodes:2 x Node:   - CPU: Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz  - Memory: 1.0Ti  - Storage: 6x 3.5 TiB  - Network: 2x Mellanox Technologies MT27710 Family [ConnectX-4 Lx]2x Node:  - CPU: Intel(R) Xeon(R) Gold 6342 CPU @ 2.80GHz  - Memory: 1.0Ti  - Storage: 6x 3.5 TiB  - Network: 2x Intel Corporation Ethernet Controller XXV710 for 25GbE SFP28I used following ISO image to install the nodes:  - ISO used for install: phoenix.x86_64-fnd_5.6.1_patch-aos_6.8.1_ga.iso After I installed the nodes I run following command on one of the CVM to create a new cluster:  - cluster -s 172.19.1.121,172.19.1.122,172.19.1.123,172.19.1.124 create But short after the cluster creation process stuck and shows the following message in a refreshing state: (Waiting about 12h but nothing has changed)Waiting on 172.19.1.121 (Up) to start:DynamicRingChangerPithosInsightsDBAthenaMercuryMantle

Deployment of VM in Nutanix

Hi,Can someone please help me with some questions?We want to deploy our appliance in nutanix, appliance means , we have iso/ova images which we want to deploy in the nutanix on-premise hypervisor.Does the standard ova image will work without any issue or there are some considerations i need to take care of ?If i test it in the cloud cluster and use it without any issue, can i be sure that this works perfectly fine with the on-premise AHV hypervisor? if not what do i need to consider ?

VMs won't power on - QEMU error

Hello, first time poster. I’ve created a one-node cluster on an intel NUC 10 (NUC10FNH) using latest phoenix image. install went fine after a couple of hardware bumps but node is up, CVM is running etc. The issue I’m having is I can’t power on any VMs I create. It only gives a generic “InternalException” error. In the uhura.out log, there are these entries “Error: HypervisorError: internal error: QEMU unexpectedly closed the monitor” and “qemu-kvm: Address space limit 0x7fffffffff < 0x4bcbfffffff phys-bits too low (39): 61”. Having a hard time trying to make sense of this. I’ve read other people running on the same hardware with no issues, maybe it’s the specific version of the CPU (it’s an i7-10710U). one-node cluster, 64GB RAM, one 500GB m.2 SSD and one 500GB SATA SSD. booting off a 64GB usb drive. Any info would be appreciated. Thank you.

Replacing (renewing) hosts for two node cluster

We have a two node cluster running hyper-V and hardware has come to EOL.We need to replace the nodes with new supported hardware and I cannot find any documentation for this, specially for a two nodes cluster. Is there any documentation available or can anyone provide the procedure? I know hardware replacement is supported for two nodes clusters, I just cannot find instructions for it. Thanks in advance

Upgrading ESXi 703c to 703s from vCenter instead of Prism Elements?

Good day nutanix community We are to upgrade our cluster from ESXi 7.0.3c to 7.0 U3s to patch for the latest CVE vulnerabilities, BUT, in the Compatibility and Interoperability Matrix there is no information about this ESXi Version so, it´s is supported this ESXi? Current AOS version 5.20.4.6 LTS upgradable to 6.5.6.7 LTSModel NX-1065-G7Can I upgrade the ESXi hosts from the vCenter LCM without needing the ISO and JSON files for they hypervisor upgrade in Prism Elements? Is the model and AOS version there compatible with ESXi 7.0.3s event though the compatibility matrix doesn’t show it, and the latest JSON file I can get from Nutanix website is 7.0.3n?

Nutanix Backplane network

Does the Nutanix Backplane network allow communication between nodes without routing ? I see the CVM’s communicate between the 192.168.5.x subnet, do the CVM’s communicate over L2 within the subnet or do they use L3 in the Nutanix internal network and if I were to disconnect the L1 Physical networking would the CVM’s still be able to communicate over this network ? I am running ESXi ontop of 4 nodes and just trying to establish if the external Physical network impacts the CVM’s on each node / esxi host, if we lost a HBA / physical adapter on that has the Backplane network would the cluster become degraded and would that CVM be offline or would it still be able to talk to the other CVM’s?  Thanks

Issue with Booting Nutanix Installation on Lenovo HX630 V3 CN Servers

We recently acquired four new Lenovo HX630 V3 CN servers to deploy the latest Nutanix AHV and AOS. Our plan is to set these up on four AHVs and the latest Prism Central. According to the compatibility matrix, this configuration should be supported.I downloaded the latest AHV (AHV-DVD-x86_64-10.0.1-219) from the Nutanix portal and created a bootable USB. However, I encountered an error when attempting to boot into the Nutanix installation process.I understand that I need to use Foundation, but my servers are new and don’t have DiscoveryOS or something similar that would allow me to discover them with Foundation tools. Could you please advise on how to resolve this issue?

About single-node clusters

I plan to introduce NX-1150S-G9 as a single-node cluster and verify Move in combination with an existing 3-node cluster.Q1. I plan to create a cluster using Foundation VM, but can I create a single-node cluster this way? I think I can proceed with the wizard with one node selected, but please let me know if there are any precautions or other methods required.Q2. Can a single-node cluster be registered as a source or destination cluster in Move? I have not verified this, but I believe it is probably possible.Also, the single-node cluster I am talking about is not CE, but commercial. I look forward to your replies.

Why CVM can not use all LACP bandwidth

We have eight XC nodes installed, each one connected to two 100Gbps switches ( 200Gbps btw two switches) by using two 100Gbps MLNX CX-6 network adapters.  AHV and switches configured with LACP (Active-Active). After installation, we ran bandwidth with iperf:AHV to AHV could reach to 188Gbps ( 1 port with 20 threads) CVM to CVM was very close to 90Gbps (The total BW always was about 88Gbps, even we used multiple ports with multiple threads)So CVM can only use the bandwidth of one port of lacp for traffic?

How to add 2 more tape drives to a tape library in Veeam

I currently have a Quantum Scalar i3 tape library with 4 drives. I need to add 2 more drives to the library in Veeam. We bought a new SAS card, and have not yet installed it into the tape server. When I do, and connect the 2 new drives to it, I am unclear as to what I will need to do in Veeam to get it to recognize that there are now 2 more drives in the library, so I can add them to the correct media pool. Will it automatically see them?
