DRS and maintenance mode, not moving off VMs

I have a customer with a 2 node DRS/HA cluster. I put one node in maintenance mode, expecting the VMs to move off automatically. They did not though. The host just said it could not enter maintenance mode, and waited for the vms to move or power off. I vmotioned the VMs off manually.

I would like the 2 node clusters to do automatic vmotion of VMs when entering maintenance mode.

Is this something to do with admission control? When I selected to enter maintenance mode, a prompt came up saying "the requested operation may cause the cluster to violate its configured failover level for HA, do you want to continue". Its a 2 node cluster, with HA configured for admission control, and host failures of 1.

DRS is on and set to fully automatic, with defaults for VMs.

Try disable Admission Control and then try again put the host in maintenance mode, if host goes to maintenance successfully your "problem" is really related to admission control. Anyway, to read more about admission control, see: HA Admission Control the basics – Part 2/2

Yes it is.... When having a two node cluster with admission control enabled and host failures = 1, you can't enter maintenance mode without disabling it. Having one host in maintenance mode and only one up and running there's no failover capacity left.... so the admission control rule would the be violated.
