[Pacemaker] [PATCH]The abolition of distinguishing a node name by a small and capital letter.

[renayama19661014 at ybb.ne.jp]

Hi Dejan,

> Are node names uppercase? And then stonith doesn't work?

The node name is a small letter. 
stonith acts, but it is not carried out because it is not found an target node.

It is caused by a mistake of the setting obviously. 
However, for a user, some kind of measures are necessary.

Best Regards,
Hideo Yamauchi.
