Sun Cluster Data Services Developer's Guide for Solaris OS

xfnts_validate Method Code Listing

This method verifies the existence of the directory that is pointed to by the Confdir_list property. The RGM calls this method when the data service is created and when data service properties are updated by the cluster administrator. The Monitor_check method calls this method whenever the fault monitor fails over the data service to a new node.
