+.. note::
+   Ironic manages OneView machines either when they have
+   a Server Profile applied by the driver or when they don't have any Server
+   Profile. Trying to change the power state of the machine in OneView without
+   first assigning a Server Profile will lead to allowing Ironic to revert the
+   power state change. Ironic will NOT change the power state of machines
+   which the Server Profile was applied by another OneView user.
