HiI'm hoping someone has a similar setup.  I originally posted this question a month or so ago but the answer I received isn't correct.  The post has been marked as solved so I'm unable to reply hence why I'm opening a new one.  I think  there was a misunderstanding  with my  described setup in the previous post so I've tried to make it clearer here.  This is tricky to explain without diagrams so I appreciate this may be difficult to provide a valid answer and I may not get a response.Our SetupWe have a 2 sites connected by fast links with one Nutanix cluster at each site (16 nodes in each Nutanix cluster).  These two Nutanix clusters make up 1 stretched ESXi cluster hosting mainly Window servers.  We then use Metro availability to replicate between these sites\Nutanix clusters.So in short - One ESXI cluster that's stretched across two sites and we use Nutanix Metro to synchronously replicate.On this environment we host a number of VM guest failover SQL clusters (2 nodes in each cluste

All,I ran the VM HA test failover; similar to another user, here Nutanix X-Ray VM High Availability Test timeout I got the 120 seconds timeout. So I raised a ticket. However one issue I did have is the powered off host was not powered back on again. All validation tests when I discovered the targets were good. I have included this in the support ticket for now, but wondering if anyone else has seen this? Older G5 Nutanix, 3 Node cluster, AOS 5.20.3, PC 2022.1.

I have just changed disk 0 and disk 1 which were SSD SATA 480gb and now are SSD SAS 1.92tb - Prism still identifies them as SSD-SATA - Why? or have a missed something?Also how do I know if they are in a RAID config or whether the system has just picked them up as single disks?The new drives should run like hot snot, how do I check that they are running faster than the old SATA drives - still have 2 hosts with old drives , I plan to complete the change over tomorrow.  Or will I only see speed increase when all hosts are complete?

I want to Install Nutanix with VMware 6.7 on DELL XC 740XD Core, I use foundation 5.0.1 and AOS 5.20 (as recomendation on hardware compability), but we stuck at imaging process and log showed dependencies not met. any sugestion?I grab the log, 2021-06-04 06:27:46,980Z DEBUG Setting state of <ImagingStepValidation(<NodeConfig(10.14.43.12) @c990>) @cc10> from PENDING to RUNNING2021-06-04 06:27:46,985Z INFO Running <ImagingStepValidation(<NodeConfig(10.14.43.12) @c990>) @cc10>2021-06-04 06:31:25,810Z DEBUG Cache HIT: key(<function common_validations at 0x450a938>_()_{'global_config': <foundation.config_manager.GlobalConfig object at 0x7f3554120f50>})2021-06-04 06:31:25,813Z DEBUG Setting state of <ImagingStepValidation(<NodeConfig(10.14.43.12) @c990>) @cc10> from RUNNING to FINISHED2021-06-04 06:31:25,814Z INFO Completed <ImagingStepValidation(<NodeConfig(10.14.43.12) @c990>) @cc10>2021-06-04 06:31:25,824Z DEBUG Setting state of

Sometimes you have to mount an ISO, and historically, the only methods to achieve this on G6 and G7 platforms were:  1) by using the IPMI Java console or 2) by mounting the ISO directly from a CVM (KB-4616) With BMC 7.11, we have an added option to mount the ISO directly from the HTML5 IPMI console.  For more details, please check out BMC 7.11 release notes and upgrade today for this and many more new features and security enhancements!

Has anyone ever attempted a Host book disk repair and encountered this issue before?     All cables and SFPs are plugged in as if it were still in production. Have not yet attempted to rebuild via foundation as these were the steps provided by Nutanix support:  https://portal.nutanix.com/page/documents/details?targetId=Hypervisor-Boot-Drive-Replacement-Platform-v510-Multinode-G3G4G5:Hypervisor-Boot-Drive-Replacement-Platform-v510-Multinode-G3G4G5   Steps Taken: Downloaded and burnt phoenix.iso to USB Booted USB into Phoenix Kicked off Repair Host boot Disk and uploaded whitelisted ESXi image Encountered error I have a case open with support and have escalated and figured that while i’m waiting I could ask the community. Will provide a response here once we figure out the issue. Cheers All!   (Edit: I posted this in the CE forum by accident)

Hi. I’m looking for some experiences in migrating windows user vms from acropolis hypervisor to vmware esxi. I tried and followed severals KBs and articles but none were successful. After powering on windows VM on esxi, they immediately go to the famous “blue screen” and don’t recognize the disk. Articles that I followed: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA032000000PMcKCAWhttps://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000098T7CAIhttps://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-Prism-v5_19:mul-vm-export-as-ova-pc-t.htmlhttps://next.nutanix.com/move-application-migration-19/want-to-export-a-vm-from-ahv-here-s-how-37275Has anyone has experience with this ? Can you help me ? Best regards

So - I have been trying to get some sort of automation of my Ubuntu VM creation in Prism, either by setting up a template machine that I would later modify using cloud-init custom scripts, or even better using a custom cloud-init script at creation to run through the “Ubuntu autoinstall”  I have tried a few times now to install an Ubuntu server by clicking my way through the GUI and then using the resulting .yml file to try and install a VM from scratch… Using “clone” from a template I can use a custom script to change hostname and so forth, but still having some problems changing the network settings (saying they are disabled by system.cfg). I guess I will be able to figure that part out eventually, but my main goal is to be able to register a new machine in Netbox, and from the info I have entered there automatically create a cloud-init fileand use that to trigger VM creation in Nutanix…  When I try to create a new VM - mounted with the Ubuntu 20.04.4 installer ISO and a 100GB disk -

Hello,I need to create several Windows Server 2019 standard, virtual machines that run in AHV (Nutanix cluster of 3 nodes nx-3170-g8, with 2x16 cores in each node) hosts that i need to buy licenses for. But i do not seem to find a calculation method for licenses).I found that i can go for per core licensing of physical cores (3*2*16 = 96 cores) which would help reduce costs since the total number of virtual cores that need to be configured is more than 200 v-cores.i would like to confirm if this approach is correct? i.e. licensing the number of the physical cores of nutanix appliances? and if anyone did it successfully?Thank you in advance,

I read that we can able to export the AHV VM in OVA format via Prism central GUI if we have both AOS and Prism central supported version. I need to know is there any way to do the same via PRISM CLI. If so,please share me any link for that. Thanks. -JAI

Hi,I’m trying to update a Nutanix env, from Prism Element. Using the web, in LCM, I see version 5.20.2 being in there, but when trying to upgrade to 5.20.3, I get the following error:Update of nutanix.nos failed on 192.168.0.2 (environment cvm) at stage 1 with error: [Failed to perform AOS upgrade with error [Preupgrade task [57c7e9a1-ebc9-495d-a848-2ead17251730] failed/aborted with message Version 5.20.3 is same as the current version 5.20.3]]LCM is at 2.4.4.2. NCC check done previously, nothing to report. Here the LCM dashboard. Any ideas on how to resolve this? Thanks a lot in advance. BTQ: I’m working within a lab environment. 

New to Nutanix and trying to understand HA for management like in VMware.  In VMware we setup vCenter HA with an active/passive/witness.  Is there something similar in Nutanix?

HiI'm hoping someone has a similar setup.  We have a 2 sites connected by fast links with one Nutanix cluster at each site (16 nodes in each cluster).  We use Metro availability to replicate between sites.  We have 1 stretched ESXi cluster hosting mainly Window servers.We have a number of VM guest failover SQL clusters (2 nodes in each cluster)  which require shared storage and therefore require the use of Nutanix Volume groups.  Each VM is connected to the volume group via ISCSI.We can't use Metro replication to replicate these VMS and their associated volume groups to the other site as you can't replicate volume groups with Metro availability - it's not supported.So, the only other option is to use Async replication.  Here are my questions:In the manual the conditions for Async say  "Do not have VMs with the same name on the primary and the secondary clusters. Otherwise, it may affect the recovery procedures"Q: If we failover the async protection domain containing the cluster node VM

Hi all, I’m trying to create additional admins accounts with LDAP authentication on Nutanix. I’ve got clusters up and running, got LDAP working, and the generic RBAC ‘VM admin/VM read only’ etc accounts (that I’m creating) are all good. But I thought Nutanix had added the ability to create a full cluster admin with AD authentication rather than creating local ones on something like prism central now? Or am I mistaken? (If someone has a way of doing this, it would be much appreciated). Kind Regards,SiW

I used X-Ray to do a performance testing for the Nutanix cluster. After added the target, and I do a Peak Performance Micro benchmark test. All the process has worked well. but when the performance testing is running, there is no I/O performance graph, only display the 3 graphs as cluster CPU usage,cluster network received, and cluster network transmitted. I cannot find the I/O performance information from the graph. I have meet this kind of problem many times. and the x-Ray version is 3.11.As the beginning test, the timezone is not right and I have ever adjust the time of X-Ray VM. 

HiI used X-Ray 4.1.3 to do a test of VM High Availability in a cluste which includes 6 Lenovo HX nodes installed ESXi 7.0 U2, I tested several times and all are failed. The test failed in the phase of after poweroff the Host and reestablish the workload in 120 seconds. All are time out in 120 secs. I checked the VM which has already HA to another host, and the VM is already restated and the IP already obtained. So this is the timeout issue. seems if the timeout  value is larger, the test will be successfully. but I cannot find the place to adjust the 120 secs value.My question  is “ Is there any way to adjust the 120 sec value for the VM high Availability test”? 

Hi All,I want to test block storage, file storage and object storage. How many nodes are needed for the minimum cluster size? Is there a recommended configuration？
