We have our Nutanix 5 node cluster installed with VMware vSphere 7.0U3. RF=2 so I should be bale to withstand a 1 node failure. I would like to test the HA capability of VMware/Nutanix by taking a node offline abruptly and ensure everything works as expected before placing production workloads on it.I was thinking of placing a test VM on a node and then pulling the power cables and ensuring that VM is powered up on a remaining host.Does anyone have any better or preferred way to test HA?

Get all VM's of storage container in cvm with acli
Hi!We are running about 100 vm’s in our cluster - so find out a specific information manually for each vm is pretty hard.I want to get the information which vm’s are stored in a specific storage container with acli on cvm.I know that i could perform acli vm.get <vm-name> and look for the source_nfs_path of the vmdisks but it is way too much effort for 100 vm’s. Another way would be establishing a connection via SSH to /storage-container/.acropolis/vmdisk of of the cvm but i only see the vmdisk-uuids there, not the vm names i need.Is there any possibility, maybe with a for loop on each vm and a grep filter?
Hello Team,I hope you are doing well,I am learning more about Nutanix platform , can please share document(s) or KB(s) on how the physical disks are used in a Nutanix host? ie if the disk in slot 1 is reserved for CVM or m.2 is reserved to install the OS,I want to have my own guide that shows all models with their own disk layout according to their possible combinations -single SSD , dual or quad SSDs the rest of the slots are populated with HDDs -hybrid-or all slots are populated with SSDs ..ect.BRAdel

Does AOS 6.x support Fault-Tolerance on ESXi 7.x ?
As title, Does AOS 6.x support Fault-Tolerance on ESXi 7.x ?If positive, does it support more than 4 FVTM in an ESXi 7 host ? I had read https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-57929CF0-DA9B-407A-BF2E-E7B72708D825.html . Can I change parameters to support more than 4 FTVMs in an ESXi host?
Hi, One of my employees deleted 2 VMs with the name like xxxxxxxxxxxB1234 and xxxxxxxxxxxxxB1235 and at the same time xxxxxxxxxxxxxT1234 and xxxxxxxxxxxxxxxT1235 were deleted. (Logs show that he deleted them like less than a minute later) He claims that he did not touch those two. Is it possible that two VMs can be corelated somehow and deleting one triggers deletion of another one? One was bench and one was test. The only difference in name was one letter.
Nutanix Local Key Manager
Can someone provide a brief explanation of Nutanix local key manager and how it handles the following in ‘???’:key access: access to the management console is restricted to authorized individuals abased on job function. changing / updating keys: encryption keys are updated from the management console, software encryption (rekey button) if necessary. revoking keys: ??? (when does revoking keys happen?) recovery keys: ??? (how do you recover if you have the key backup?) archiving keys: keys are archived (backed up) from the management console, managed keys where you download the key backup by setting up a recovery password to decrypt the backup file. activity logs: ??? (is there activity logs for keys? If yes, where is this stored and how long is the retention before the activity is overwritten?)BTW: I have this link already Native Local Key Manager (nutanix.com) but is does not have any details of the Thanks in advance.
What does ADS consider when making migration decisions regarding CPU (AHV)
What metrics are considered when Acropolis Dynamic Scheduling makes a migration decision on AHV related to CPU usage? Does ADS consider only CPU usage on the Host? Or does ADS take into consideration other VM or Host metrics such as CPU Ready, Co Stop, and/or Steal Time?
