Hi Mario -- I was just looking into this myself, today.  I think the
lowest cost that you'll be able to find is an IPMI card for your
motherboard (as long as the motherboard in question supports it).  To
find out you'll need to look into your specific model of motherboard
and see what is needed (or even if it is possible).  IPMI cards aren't
foolproof and have their own problems; but it's better than nothing, I
would think.<br>
<br>
I think that your idea for fencing at the switch would be workable; but
how exactly to accomplish that would depend on the switch that you were
talking about; as the commands (and even if external ability to do so
is available) would be switch/manufacturer-dependent.<br>
<br>
Of course even lower cost (but even more problematic) is simply using
external/ssh to shutdown the server to be killed, as that should be
free.<br>
<br>

  <pre wrap="">Hello,

Can you suggest me a list of stonith devices compatible with 
pacemaker?

I need a low cost one.

I have also another idea to build a low cost stonith device:

I have intelligent switches. To stonith a node I can send to
 a switch the command 
to turn off all ethernet ports linked to the node to be fenced. 

So the node is powered on but it cannot do any harm because 
it is disconnected 
from network.

Is it a good idea? How can I implement it?

Thanks in advance for any help.

Mario
