I have a few NX G8 nodes I want to install and configure, however the ToR Switches currently available are 1G switches (I have ordered 10G switches but they are late). I have a few questionsIn the pink circle above, the left port is Shared IPMI (10G) and the right one is its failover (as I’ve seen in NX Hardware specifications), however the speed for Failover port is not specified. Does any one know whether it’s 10G or 1G? And it is activated by default or should I go into BIOS Setup and activate the port during boot? My idea is to use this Failover port for Nutanix imaging and subsequently use it for CVM, Host and User VM traffic (temporarily). Has anyone tried this before? Any issues during Foundation imaging? I’m aware there will be performance issues when it comes to AHV/CVM services running as well as VM performance. Thanks everyone in advance!

Hello,Does anybody know where I can find the 'Nutanix AHV Best Practices', as found in the google search below, I can't for the life of me find it.Specially looking for best practices for different workloads, and that article based on the description seemed to hit the nail on the head regarding higher clock speeds for database workloads for example.i find that a lot of Google links just end up with a "Not Found or Forbidden" message.

Hi everyone, i have a question that can we schedule shutdown and restart CVMs, AHV host automatically? For example, I want to shutdown system at 9 P.M and restart it at 9 A.M. It could be scripts or anything else. Hope your helps 

Hi everyone,After upgrade LCM to the latest version scavenger process scheduled every 2 minutes! It drives me crazy!/home/nutanix/bin/scavenger.py --interval_secs=120 --logtostderr=TrueSo if anyone know how to reschedule this process to 10 or 20 minutes, I’ll be very pleased.

we have three new hpe dx380 gen 10 servers for nutanix AHV installation, Can we configure LACP on the Nutanix AHV cluster with new HPE server? what is the prerequisite for LACP configuration, and what we need to do?

Hello,On our new infra NUTANIX AHV, when I try to connect with Powershell I've this error : PS > $PrismIP = "<Prism ip>"PS > $userName = "<AccountUser>"PS > $password = ConvertTo-SecureString -String "<ComPlexE%Pass@ord>" -AsPlainText -ForcePS > Disconnect-NTNXCluster *PS > $connection = Connect-NutanixCluster -Server $PrismIP -UserName $username -Password $password -AcceptInvalidSSLCerts -ForcedConnectionConnect-NutanixCluster : The remote server returned an error: (401) Unauthorized.At line:1 char:15+ ... onnection = Connect-NutanixCluster -Server $PrismIP -UserName $ ...+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~    + CategoryInfo          : InvalidArgument: (Nutanix.Prism.Common.NutanixCluster:NutanixCluster) [Connect-NutanixCluster], WebException    + FullyQualifiedErrorId : The username or password you entered is incorrect.

So i uploaded my new certs, everything went fine, prism then restarted, but then I get the following message when trying to connect again.refused to connect.I’ve stoped the prism service and did a cluster start, prism is showing as running but I can’t get anything other then the above message.I can’t even update the certs again incase its a cert issue as the web interface is not working and I can’t for the life of me find a way to do it via ssh.

hello @all,I tried to create a VM with a vdisk on a specified storage_container via APIv3. The JSON I entered:{ "api_version": "3.0", "metadata":{ "kind":"vm" }, "spec": { "cluster_reference": { "kind": "cluster", "uuid": "<uuid>" }, "name": "<name>", "resources": { "disk_list": [ { "storage_config": { "storage_container_reference": { "kind": "storage_container", "uuid": "<uuid>", "name": "<name>" } } }, { "data_source_reference": { "kind": "image", "uuid": "<uuid>" } }, { "disk_size_mib": 10000 } ], "memory_size_mib": 4096, "nic_list": [ { "nic_type": "NORMAL_NIC", "is_connected": true, "ip_endpoint_list": [ { "ip_type": "DHCP" } ], "subnet_reference": {

Ladies/Gents,Second time this happens. First time it did, I did not know how to fix this and did a reinstall. This time I am trying to find a way to avoid going down the full reinstall route…The issueAfter a power failure, in my area, the power may come back for like 5-60 seconds and then off again. This may happen once or twice after the power failure. In that case, what happens, is the AHV seems to mark the two NVMe drives as not available (I have one SSD, 120GB Western Digital booting AHV - so boot drive, and two Samsung EVO 1TB) and due to that, CVM and all VMs are gone.Booting off a USB stick with Linux Mint we can see the drives listed: All I can find is info that requires the CVM, what is gone in this case…So how can this be fixed? Is it a matter of booting with the Nutanix CE USB and doing a repair? Is there something that can be done on AHV (what of course I do have access to) that will 'unflag' the disks as bad (what they are not - if I do reinstall the whole thing and start

I need to stop one as I didn’t remove a large disk from it before starting.

Hello, warriors of the digital ageCould you help a beginner in trouble? I took an internal snapshot yesterday to prepare for a problem moving nodes from an existing cluster to another cluster The previous one was done well, and the snapshot was about 1.8gb, but I found that even though I deleted the snapshot, I still had about 1tb of capacity leftI checked if the data was increased on another vm, but it didn't, so I think it's because of the snapshotErasing the snapshot doesn't reduce the capacity. What should I do?Where should I check first?AOS 5.20.3.5 / ESXI7.0 u2a  

We are planning to migrate 2000 VMs from VMware to Nutanix, I am looking for Power shell script, which can automate the plan creation and start cutover. 

Is there any specific requirement port speed on TOR Switch for Nutanix Cluster running NVME + SSD storage? Is still good running 10Gb Switch to cover NVME + SSD performance? Thanks

I would like to create a new scenario with Lenovo HW or modify one with NX HW to Lenovo but I don’t how I could that. Anyone could tell me if is it possible?

Hello Team, We are trying to migrate Fortisiem VMs ( Collectors & Supervisors ) from VMWARE to AHV using Move but facing Authentication Failed issue. We verified and we have root access to the VMs and all the rights on the 2 VMs.  Also, the distribution of VMs are Redhat 4.4.7-23). Maybe it’ s a problem of Os compatibility, what do you all think.

Hi, Can we use Aruba 25g DAC cables with Nutanix servers?  Thanks,

Hi, Im trying to understand how a Nutanix node works fine even if it’s connected to two switches not in stack. And i found that only one interface is enable when using the active-backup mode, but when im checking on the switches i fount that both interfaces are up. So, im asking if there is a way to check which interface is actif from AHV or CVM.     

Hello,I’m trying to mount NGT to a VM through the REST API. However it does not seem to work.AOS version: 5.20.3PC version: pc.2022.4.0.1I tried these two requests:https://IP_ADDRESS:9440/PrismGateway/services/rest/v1/vms/72a3b676-906d-42b1-ad1e-ac8d63cf529b/guest_tools/mounthttps://IP_ADDRESS:9440/api/nutanix/v3/vms/72a3b676-906d-42b1-ad1e-ac8d63cf529b/guest_tools/mountHowever none of them seem to work. Do you have an idea why ?Thanks

We are planning for migrate using Nutanix move from ESXi to AHV.Does it require local admin credentials for migrations for any account with root preveliges is fine.I know the appliance will try to install VirtIO drivers and uninstall vmware tools.But can it be by passed or local admin access is required during migration.Also have another question on Domain controller and Citrix vms running on the vmware ESXi.Are there any pre-requisites to be done before migration. ThanksSriram  

Hi,Does anyone replace a failure capacity SATA HDD on Nutanix NX Series with same model HDD before? Is it possible/or compatiable? The NX Series already EOL!
