-n, --on Power on the target hosts.
-f, --off Power off the target hosts.
-c, --cycle Power cycle the target hosts.
-r, --reset Reset the target hosts.
-s, --stat Get power status of the target hosts.
--pulse Send power diagnostic interrupt to target hosts.
--soft Initiate a soft-shutdown of the OS via ACPI.
--on-if-off Issue a power on command instead of a power cycle
or hard reset command if the remote machine's
power is currently off.
--wait-until-off Regularly query the remote BMC and return only
after the machine has powered off.
--wait-until-on Regularly query the remote BMC and return only
