We have one server where the host exists maintenance mode automatically after reboot. Ideally, the host should not exit maintenance mode unless we do it manually. I am not sure what particular setting causes this behavior. Other servers in the datacenter works well.
Any idea what causes this or how to prevent this ? ESXi version 6.5
Are all hosts running on the same version/build?
I've seen such a behavior with one of previous patches (after an update), but can't tell you for sure with which one.
