With power host management workflows you can reboot or shut down a host.

You can access the power host management workflows from Library > vCenter > Host management > Power in the Workflows view of the Orchestrator client.

Reboot host

Reboots a host. If the Orchestrator client is connected directly to the host, it does not receive an indication of success in the returned task, but rather loses the connection to the host if the operation succeeds.

Shut down host

Shuts down a host. If the Orchestrator client is connected directly to the host, it does not receive an indication of success in the returned task, but rather loses the connection to the host if the operation succeeds.
