Remove Hyper-V host from Nutanix cluster
Quick guide how to remove Hyper-V host from Nutanix cluster and from Microsoft failover cluster. Order is very important, as Nutanix AOS is very smart and will not let you remove Hyper-V node if it is part of Microsoft failover cluster.
NOTE #1: do not remove more than one Hyper-V host from failover cluster. Removing Hyper-V node from cluster causes server reboot, which means – CVM is restarted as well
NOTE #2: do not remove more than one host from cluster at same time (again AOS will not let you evict next host if another evict task is in progress)
NOTE #3: there is trick, to speed up node evict process, if you are interested open SR for Nutanix support and folks will help you out.
- Drain roles off Hyper-V host
- Stop CVM by loggin in over SSH to CVM and run cvm_reboot_now -P
- Enter Hyper-V host in maintenance mode
- Remove Hyper-V node from failover cluster in SCVMM
- Wait for Hyper-V host to restart and CVM boot up
- run cluster status – make sure all services are running – cluster status | grep -v UP – command

if can see Up next to every CVM and no Apps DOWN (like on below example), proceed with next step.

- Log in to Prism Element –> hardware tab –> table –> mark host –> Remove host
- Wait for Acropolis to complete node removal.
