I'm interested in knowing how you configured this constraint. As I
understand it now, there should be one primitive only in the cluster to
address the PDU, which would be used to perform STONITH on all nodes
that need one. You probably used a location constraint, but how exactly?

Dominic, I'd be interested to know how you configured the apcmastersnmp
plugin. Would you mind sending me your configuration?

Thanks.
