Sun Cluster Overview for Solaris OS

Resource Groups

Resources that are managed by the RGM are placed into resource groups so that they can be managed as a unit. A resource group is a set of related or interdependent resources. For example, a resource derived from a SUNW.LogicalHostname resource type might be placed in the same resource group as a resource derived from an Oracle database resource type. A resource group migrates as a unit if a failover or switchover is initiated on the resource group.
