Applies to:

Solaris Cluster - Version 3.1 and later

Goal

Before the release of the Sun Cluster 3.1 9/04 software, the Resource and Resource Group dependency model used by Sun Cluster 3.x was fairly simple.
As of the release of Sun Cluster 3.1 9/04 software, this model has been significantly improved with the addition of the Resource Affinity model.

This document explains this Resource Group Affinity Model in detail.

Resource Dependencies are explained in Document: <Document 1021014.1>
