Hello,I am conducting a test using NX-3050 equipmentI know it's an old Node-Model and I have previously installed it with AOS 5.20.2.1As you can see now, we are going to test the upgrade using LCM in AOS 5.10.11.1LCM was installed as shown using 2.5.0.2.32663 Dark-site​​​​​I uploaded the file 5.20.2.1 because I saw the opinion that if the AOS version for upgrade is EOS,it might not be displayed on the screenNo matter how long I wait for the LCM in the setting window, there is no screen, so should I reinstall it? I think I saw the opinion that the AOS version was modified because it was low, so is it impossible to update using the LCM DARK site? Thank you for reading the long article and I would really appreciate your opinion

Dear All,New to Nutanix Frame here. Hence, please just let me know if I left out any essential information.We are running a non-persistent account on Frame. We noticed that AD objects that are related to instances that have been removed from the Frame account, e.g. by manually terminating them from the Status page, remain in AD. The expectation would be that these would be purged automatically. We used the Nutanix Frame AD Helper to verify that the service account does have the necessary permissions. Also, we are seeing that new machines are being created without issues.

Hi,I just want to ask if its possible to use the 1 GbE interface while using the 10 GbE for back up network in case the 10 GbE switches fails, if its possible how to set it up?

CVM On LACP networks, Physical switches use MLAG technology，CVM bandwidth performance cannot be improved, and the maximum can only be 10Gb. 

Hello. I have a question about upgrading AOS and AHV.I understand that upgrading AOS and AHV requires restarting nodes one by one, so I need to calculate memory, CPU, storage, etc. and free up enough space.There are customers who are currently using more than 90% of cluster memory.cpu, there's plenty of storage.We recommended turning off underutilized VMs to free up memory capacity, but they said it was impossible.It also says that disabling virtual machine high availability reduces memory utilization to less than 60%.However, it is recommended that you disable virtual machine high availability because it is a feature for recovery in the event of a host failure.If you turn off this feature during an upgrade and an unexpected failure occurs during the process, it can be a problem, right?In conclusion, I would appreciate it if you could tell me the correlation between upgrade and virtual machine high availability.

We have a scenario where we want to show session based stats for any particular VM. Using below API we can get the CPU stats for the whole VM.https://{{cluster_ip}}:{{port}}/PrismGateway/services/rest/v1/vms/{{uuid}}/stats?metrics=hypervisor_cpu_usage_ppm&intervalInSecs=60&startTimeInUsecs=1607965687547284&endTimeInUsecs=1607967487547284Is there any way or any API that can can give stats bases on machine sessions?

Hi there,I hope you all are having a wonderful day!I have a Django application running. I want to integrate a feature which allows users to connect to their specific VM remotely (via VNC). I did find a lot of help related to APIs, but nothing related to something like this. I’d really appreciate if someone can help me out with this one, as I’m absolutely lost here.Thanks in advance.
