Sun Cluster Data Services Planning and Administration Guide for Solaris OS

Registering a Resource Type

A resource type provides specification of common properties and callback methods that apply to all of the resources of the given type. You must register a resource type before you create a resource of that type. For details about resource types, see Chapter 1, Planning for Sun Cluster Data Services.

How to Register a Resource Type

Note –

Perform this procedure from any cluster node.

Before You Begin

Ensure that you have the name for the resource type that you plan to register. The resource type name is an abbreviation for the data service name. For information about resource type names of data services that are supplied with Sun Cluster, see the release notes for your release of Sun Cluster.

Steps

Become superuser on a cluster member.

Register the resource type.
# scrgadm -a -t resource-type
-a

Adds the specified resource type.

-t resource-type

Specifies name of the resource type to add. See the release notes for your release of Sun Cluster to determine the predefined name to supply.

Verify that the resource type has been registered.
# scrgadm -pv -t resource-type

Example 2–1 Registering a Resource Type

The following example registers the SUNW.iws resource type, which represents the Sun Java System Web Server application in a Sun Cluster configuration.

# scrgadm -a -t SUNW.iws
# scrgadm -pv -t SUNW.iws
Res Type name:                                   SUNW.iws
  (SUNW.iws) Res Type description:               None registered
  (SUNW.iws) Res Type base directory:            /opt/SUNWschtt/bin
  (SUNW.iws) Res Type single instance:           False
  (SUNW.iws) Res Type init nodes:                All potential masters
  (SUNW.iws) Res Type failover:                  False
  (SUNW.iws) Res Type version:                   1.0
  (SUNW.iws) Res Type API version:               2
  (SUNW.iws) Res Type installed on nodes:        All
  (SUNW.iws) Res Type packages:                  SUNWschtt

Next Steps

After registering resource types, you can create resource groups and add resources to the resource group. For details, see Creating a Resource Group.
