I'm assuming by v1 config you mean a legacy-style cluster running on 
hb2, since true external plugins (as used below) are not supported on hb1.

These two ha.cf directives are supposed to be mutually exclusive, 
meaning you should use one or the other but not both.  Does your plugin 
work if you comment out the stonith_host line?  If so, is "192.168.200.0 
off" even needed?

To be a compliant external plugin, you need to support all of the 
required operations.  Please see:

http://www.linux-ha.org/ExternalStonithPlugins

which also shows a CIB excerpt for an external plugin.
