So if the maintenance mode from the GUI is necessary to upgrade host, how to launch it from the CLI on that host?
Generally speaking, it should be doable using the api/sdk. I don't know the details. If you have many hosts, you might want to try the upgrade manager: http://www.ovirt.org/develop/release-management/features/engine/upgrademanag...

What is the difference between:
There are two different notions of host maintenance:
1. in the engine, meaning the engine will migrate away VMs from this host, not start new ones on it, etc. This applies to all hosts, not just hosted-engine ones
2. in ovirt-hosted-engine-ha, the high availability daemons. Here it means similar things, but applies only to the hosted engine vm, and is maintained in the HE shared storage (not in the engine db).
host CLI command: hosted-engine --vm-maintenance --mode=local
This one does (2.).
and RHVEM gui click action: Hosts -> <hostname> -> Maintenance?
In the past, this did only (1.), but now it does both.
