Virtualized Domain Controller Nightmare on Nutanix Hyper-V Cluster

Hi Guys

We recently deployed a Hyper-V  Nutanix Cluster , and everything looked fine until we hit the wall. For some reasons if the VM(Domain Controllers)  go down you will not be able to power it on . The reason behind this that the Hyper-V Cluster on Nutanix uses SMB3 based share as the shared storage . Unless  the Hypervisor is able to authenticate the access to the SMB3 share is blocked. In our case it was not possible because the 2 DC VM’s were powered off and unable to power it on.(Chicken and Egg situation)

Error Message I received:

error1 error2 error3

The below Nutanix article explains the below:

So the conclusion is that you must need either a physical domain controller or a DC VM that does not sit on the SMB3 share. Hopefully the Windows 2016  may come up with a solution for this scenario.

Update1: As a last resort , I changed the Virtual disk path from on the DC VM from the FQDN  of the cluster name to the IP address of the cluster , voila I was able power it on the 2 VM’s(but I do not have any clue how this has worked)

Nutanix Best Practices for VMware

Hi  Folks

Recently we got an opportunity to work with Nutanix Converged Solution . When we deployed there was some customization that we need to make on HA / DRS Cluster settings to realign the configuration according to Nutanix – VMware Best Practices
(These information were provided by the support team)

Note1: In Nutanix Cluster is created with single Datastore the Vsphere HA will popup error related to HA Heartbeat stating insufficient datastore for heartbeat , that could be suppress as below

Note2: In HA Cluster the VM restart priority and Host Isolation Response need to be changed for CVM’s as below:
bestpractice_cluster_vm_settings_1

Note3:  The VM Monitoring for CVM’s need to be disabled
bestpractice_cluster_vm_monitoring_1

Note4: In DRS Cluster the Automation level for CVM’s need to be disabled as well
