[Pacemaker] Problem with external/ipmi stonith plugin?!

[Moritz Krinke]

Hello,

i'm trying to get the ipmi plugin to work using the configuration shown. The plugin always reports rc 1 to pacemaker.
I had a look at the ipmi script and verified that the cmds used to indeed work (ipmitool is working as is the connection to the ipmi device if i set the needed env vars)

But, looking at the script, i find it strange that it seems to expect having the hostname of the machine which is supposed to be controlled as a seconds argument.
I echo'd all passed parameters to logfile, but the script never gets passed a second argument.

Is the plugin broken or am i missing something in the configuration?

Im quite new to pacemaker/corosync so forgive me for a maybe obvious fault ;)
