Edward, There are some man pages for Sun Cluster's use of pmf that might provide some of the information you are looking for. The online collection of Sun Cluster section 1M man pages for the 3.2 1/09 release are here:
http://docs.sun.com/app/docs/doc/820-4685/6ng4psver?a=expand These are the PMF-related man pages: pmfadm(1M) pmfd(1M) (aka rpc.pmfd(1M)) Hope this helps.
