Hello, 
Sorry for my newbieness. After chatting in the #linux-ha channel, Kleind and 
Rubeus80 give me a hint that the 'node' parameter is automatically forwarded 
by linux-ha to the wti_nps. This gives me a clue, that maybe since uname -a 
results in station8.enterprise.com whereas in the wti it's called 
only 'station8', stonithd fails to command wti_nps correctly. Telnet command 
using full node name confirms this.

So, I rename the nodes to shorter names: station8 and station9, make the httpd 
service fails by zeroing the httpd.conf in station8, and.....  station9 
successfully 'fence' station8. Wow! So happy.

I'm exploring more tonight. Linux HA is awesome!
