CFS PostOnline Trigger

Version: SFCFS 5.0MP3 on Solaris 10u9.

A "postonline" VCS trigger perl script has been created and tested at the command line using the "hatrigger" utiltiy but the "postonline" trigger script  is not automatically run by VCS when the SF Cluster File System is mounted.  We see in the VCS EngineA Log where the "postonline" trigger is run for other Service Groups (both parallel and failover), but it is not run for the SF-CFS Service Group. 

Will VCS run the "postonline" Trigger script after the CFS Service Group is Online?  if so, how can this be acomplished/configured?

TIA --
