Sun Cluster 3.0 U1 Data Services Developer's Guide

xfnts_start Method

The RGM invokes the START method on a cluster node when the resource group containing the data service resource is brought online on that node or when the resource is enabled. The xfnts_start method activates the xfs daemon on that node.
