I use fence_ilo and fence_apc (CS4U3) - both first poweroff and then
poweron too. This is only a problem in a two node configuration because
both nodes send the poweroff command and non of them can send the
poweron command because both are down.

The most fence-devices have an option or action tag, that is not
available via the cluster configuration tool. They can be used to force
a reboot (default) or an poweroff. 

<fencedevice action="off" agent="fence_ilo" .../>
<fencedevice agent="fence_apc" option="off" .../>
