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.
