One CVM upgrade is stuck at “Waiting for reboot and upgrade completion” for almost 3 hoursWhile other two nodes were upgraded successfullyAny help will be appreciated. 

We are using Nutanix Prism, both Central and Elements.I heard that Nutanix Prism 2024.03 will no longer support the v3 API.However, we are currently using Nutanix Element APIs (v1, v2, v3), with a few Central APIs, but most of our usage is with Element APIs. How are things going? Will Nutanix deprecate all "Element" APIs from v1 to v3? Also, how can we migrate from Central API v3 to v4? There are many APIs, and we don't have much time to analyze all the v4 APIs. Thank you.

Scheduled Rubrik Nutanix backups fail with an Internal server error similar to this link: Nutanix backup fail with "ENTITY_READ_ERROR" and "Reason: Internal error."Has anyone had success resolving this error? I was able to get a manual snapshot by changing the snapshot type from Automatic to Crash Consistent, then put the vm back into the SLA but it failed again with a different error: "Failed to get changed regions for snapshot_file_path" but one thing at a time for now in the Rubrik console and there are no issues on the CDM as a protected VM.

Hi guys, i have a problem with my nutanix ce in my new hardware lab, i still got the NTP error even i already change and confirm my ntp configuration is correct, anyone have some problem or can help me to troubleshot my issue?  the error code is “error alertLcm prechecks detected 1 issue that would cause upgrade failures.Check 'test_ntp_server_reachability' failed: Failure reason: Cannot upgrade if the configured NTP server(s): ['0.id.pool.ntp.org', '1.id.pool.ntp.org'] are not reachable.

Hi, I’m new to Nutanix and I have many questions that I would appreciate getting answers to. It’s a very confusing topic for me and I looked for answers but either didn’t find or just got more confused. I apologize if the answers already exist on the forum.I’m helping a friend setup a 3 node cluster on Nutanix CE. Each node has 1TB 2.5” SSD for CVM, 1TB 2.5” for data and a 32GB/64GB USB drive for AHV. We were able to install CE on one of the nodes as a start, with some errors that didn’t seem to affect the installation and setup, like “Failed to start Systems Management Device Drivers. See ‘systemct1 status instsvcdrv.service’ for details”. We didn’t know what that meant or where to check, but the installation was ok.To create a 3 node cluster, do I have to setup CE on each node separately, assign IP addresses for the Host and CVM for each, and then run the command  cluster -s cvm1_ip_addr,cvm2_ip_addr,... create ? If I create a single node cluster, can I add more nodes to the cluster

Hi All, I am using prism central to import an OVA.  The OVA can be used to deploy VMs to EXSi server.When I imported that OVA, the disk import failed with the following message:Incorrect file uploaded. Disk conversion for OVA failed with err: Size of file scsi0.0 in OVA does not match size specified in OVF I check the OVF (inside the OVA), it specified the disk size as:Disk ovf:capacity="40" ovf:capacityAllocationUnits="byte * 2^30" I sshed to the ESXi server and look at the flat disk size: -rw-------    1 root     root       40.0G Feb 11 13:40 gw-3-0-20250120-flat.vmdk-rw-------    1 root     root     42949672960 Feb 11 13:39 gw-3-0-20250120-flat.vmdk They all looked correct.Are there more detail logs wrt the import, that i can see why import failed?  like for example, what the import think the vmdk size should be? Thanks, SuperJames

Hello,We have Cisco UCS servers with GPU Nivida Tesla A30 GPU and running ESXi virtualization, we will move to Nutanix over UCS and AHV instead of ESXi. What I need to know if there are any features will be affected or any limitations where be introduced when we move from the ESXi to AHV regarding the GPU card, also if there are any documents talk about this particular issue. Thanks & BRMoamen 

Hello,I have installed 3 AHV nodes in the cluster.I have 3 drives on each node:200GB - SSD Hot Tier 250GB - SSD Data Tier 250GB - SSD Data TierIn the cluster → hardware → disk table I can see that:Hot tier has ~80GB for free (the rest is occupied by CVM etc.) The first disk on Data tier has ~120GB free The second one has ~175GB free.My question is, what is the reason for the difference between those two data disks? It generates an alert that those disks are not equal but physically are.

Hello everybody,we’ve received a Nutanix Insights Update a few days ago which alerted us to the fact that there’s a critical issue with the NS204i controller Firmware on one of our DX380 servers.Currently, firmware version 1.2.14.1004 is installed and firmware revisions below 1.2.14.1013 are susceptible to file system and I/O errors.The current HPE Servicepack for Proliant 2024.11 includes the updated firmware revision 1.2.14.1018.One of my coworkers mentioned that Nutanix maintains a list of compatible HPE SPPs for the ProLiant DX servers and that I should not simply use the most current SPP to upgrade the firmware.Can somebody point me to this list? Or would it be okay to use the most current SPP to upgrade des firmware?Sorry if this question was already answered elsewhere, I’m quite new to this Nutanix thing 😊Thanks in advance,Dominik

Hi teams, i have a problem with my nutanix ce, i got the alert about “The host (x.x.x.x) is not synchronizing with any NTP server” but after i check using ssh in the cvm, and running ntpq command to check my ntp, i got the error “-bash: ntpq: command not found” anyone have idea to solve our issue?

Hi all! I am new to Nutanix and I am learning the product.We’re evaluating a possible HCI where at the moment our storage is based on a SAN which expose LUNs directly to our nodes.  Do you know if there’s a way, supported and compatible with Nutanix, to export the same LUNs to an AHV solution?  If not, is it present as a future target in the company roadmap?  Thanks a lot in advanceKindly Luca 

We have a new cluster running AOS6.10 AHV which is nearly ready to go into production it will be replacing two older clusters running ESX.  Currently it has no encryption enabled. What is the best option, pros\cons of full cluster encryption compared to Entity Encryption (VM) using storage policies?  Its a 4 node cluster and will be hosting around 170 VM’s.

Wondering if anyone has seen with Windows if I boot a legacy BIOS VM with an attached Windows ISO it automatically boots to the Windows installation.  If I try to boot it as UEFI it still boots to the ISO, does the ‘Press any button to boot from ISO’ but then tries to go to PXE/network boot.  If I press a button it does boot into the Windows installation.  Just curious why this difference between BIOS and UEFI and if anybody knows.

I have an incident with a new 3 Host cluster with NCE 6.8.1: In Dashboard show Please enter your NEXT account information to access the cluster. When I log in with my mynutanix credentials I get the following error message: Cannot validate the credentials provided The CMV IP has internet access, pinging google.com or nutanix.com resolves without problems.Could someone help me with this problem, since the Prism dashboard won't load.

Is there any way to increase the number of source ports that can be configured in a Traffic Mirroring Session? If not, does Nutanix plan to increase the number at some point?

Hello,Just wanted to know if anyone else here experienced this issue where the host in my single node cluster is not schedulable. Here is the output from acli host.getnutanix@NTNX-CVM:~$ acli host.get REDACTED172.xxx.x.xx {  cpu_usage_ppm: 0  host_overhead_bytes: 0  logical_timestamp: 1  max_mem_ha_reserved_bytes: 0  mem_assigned_bytes: 0  mem_usage_bytes: 0  memory_size_bytes: 0  node_state: "AcropolisNormal"  num_cpus: 0  pool_size_bytes: 0  schedulable: False  uuid: "REDACTED"} Initial issue I had was that I cannot power-on the VM due to this error:NoHostResources: No host is schedulable: 14 And after checking this host scheduling thing is what I thought of the culprit on why I cannot power-on my UVM. Already the following:1. Enter/exit maintenance mode2. Restart the CVM / AHV HostAlso noticed that the Prism element Hardware tab shows 0 usable CPU/RAM capacity on this AHV host. I use the version 6.8.1 and it is installed as a VM in an ESXi host.

I can’t start VM. I checked the status of the host with “acli host.get” command. Here is the output: 0.0.2.10 {  cpu_usage_ppm: 0  host_overhead_bytes: 0  logical_timestamp: 1  max_mem_ha_reserved_bytes: 0  mem_assigned_bytes: 0  mem_usage_bytes: 0  memory_size_bytes: 0  node_state: "AcropolisNormal"  num_cpus: 0  pool_size_bytes: 0  schedulable: False  uuid: "22deb90e-cd1c-48af-af43-5a3192775999"} The host is not in maintenance mode. Is there any command to flip “schedulable” to True?

Howdy y’all,I am working through getting NGT installed across our fleet of 250 VMs and need to be able to mass add cdroms to each VM in our fleet.I’ve been able to generate lists of VMs but have yet to be able to add a cdrom to any of them.I’ve been getting Bad Request Errors (400) so I’m sure it’s how the payload is being created, but no combination of settings has worked for me.I’m obviously frankensteining from across the web, but I offer you my meager script for scrutiny.Any help is appreciated!Thank you!import urllib3import getpassimport sys import ntnx_vmm_py_clientfrom ntnx_vmm_py_client import Configuration as VMMConfigurationfrom ntnx_vmm_py_client import ApiClient as VMMClientfrom ntnx_vmm_py_client.rest import ApiException as VMMExceptionimport ntnx_vmm_py_client.models.vmm.v4.ahv.config as AhvVmConfig #Disable SSL Checksurllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) #Get the credentialspc_ip ="<Prism Central IP>"username = "<Username>"cluste

Hi Anyone have a playbook that I can use accomplish the subject feat? I have to power cycle 470 VMs in groups. i.e Group1 has 45 VMs, Group2 has 45 vms and so on.

Happy Holidays & Merry Christmas! 🙏🏽😇 Last month, I concluded about a month of extensive tests and validations in Nutanix-Senate Lab with latest versions of AHV, AOS, and Prism Central verifying the following capabilities:(1) Ability to easily mass-deploy 100+ Windows 11 Virtual Desktops (Win11 VDs) in one workflow via Nutanix Prism Central,(2) Ability to quickly backup all 100+ Win11 VDs in one workflow via Prism Central “Protection Policies” to Remote Site with RPO of 15 minutes,(3) Ability to rapidly failover all 100+ Win11 VDs to Remote Site via Prism Central, and(4) Ability for users of Win11 VDs to speedily restore their own local data via Nutanix Self-Service Restore (SSR).Many thanks to Nutanix Team (Adam Farry☁️| Simon Motture, Tim Fisher, Neil Mantle, and Kevin Bacon 🥓) for all their help and engagement on this! 🙏🏽

Currently when orchestrating the creation of Network Function VMs, I am using a Prism Element V2 REST API to set VM/Host Affinity as instructed by the Nutanix team a few years ago. Is this still what is recommended or can Affinity Policies be used instead? It seems that in order to use Affinity Policy for service chaining each Affinity Policy would need to have 1 VM (the network function VM) and 1 host. 

I have some issue connecting PrismCentral using powershell. In UI I can login using AzureSSO. But  I need to use  to able to pull-out some report.
