Check your cluster.conf - it's probably already sending a "poweroff", 
then a "poweron", like this (for an APC power unit):

<fence>
    <method name="1">
      <device name="FENCE1" option="off" port="1"/>
      <device name="FENCE1" option="on" port="1"/>
    </method>
</fence>

in which case you can just drop the "on" part to achieve the desired 
result.  Otherwise you may need to hack at the fence_ilo script a bit - 
it's just a perl script.
