A resource is an instantiation of a resource type. You must add resources to a resource group before the RGM can manage the resources. This section describes the following three resource types.
Logical hostname resources
Data service (application) resources
Oracle Solaris Cluster provides the following tools for adding resources to resource groups:
Oracle Solaris Cluster Manager GUI. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster System Administration Guide .
The clsetup utility. See the clsetup(1CL) man page for more information.
Oracle Solaris Cluster maintenance commands.
You can use the wizard in the clsetup utility or use the Oracle Solaris Cluster maintenance commands to add the logical-hostname resources to the resource group.
Oracle Solaris Cluster Manager and the clsetup utility enable you to add resources to the resource group interactively. Configuring these resources interactively reduces the possibility for configuration errors that might result from command syntax errors or omissions. The clsetup utility and Oracle Solaris Cluster Manager ensure that all required resources are created and that all required dependencies between resources are set.
Always configure logical hostname resources and shared address resources in failover resource groups. Configure data service resources for failover data services in failover resource groups. Failover resource groups contain both the logical hostname resources and the application resources for the data service. Scalable resource groups contain only the application resources for scalable services. The shared address resources on which the scalable service depends must reside in a separate failover resource group. You must specify dependencies between the scalable application resources and the shared address resources for the data service to scale across cluster nodes.
