A scalable application resource is an application resource that uses shared-address resources. The shared-address resources are in a failover resource group.
Perform this procedure from any cluster node.
Ensure that you have the following information.
The name of the scalable resource group to which you are adding the resource
The name of the resource type for the resource
The shared address resources that the scalable service resource uses, which are the shared addresses that you previously included in a failover resource group
Become superuser on a cluster member.
Add a scalable application resource to the resource group.
# scrgadm -a -j resource -g resource-group -t resource-type \ -y Network_resources_used=network-resource[,network-resource...] \ -y Scalable=True [-x extension-property=value, …] [-y standard-property=value, …]
Adds a resource.
Specifies your choice of the name of the resource to add.
Specifies the name of a scalable service resource group that you previously created.
Specifies the name of the resource type for this resource.
Specifies the list of network resources (shared addresses) on which this resource depends.
Specifies that this resource is scalable.
Specifies a comma-separated list of extension properties that you are setting for the resource. The extension properties that you can set depend on the resource type. To determine which extension properties to set, see the documentation for the resource type.
Specifies a comma-separated list of standard properties that you are setting for the resource. The standard properties that you can set depend on the resource type. For scalable services, you typically set the Port_list, Load_balancing_weights, and Load_balancing_policy properties. To determine which standard properties to set, see the documentation for the resource type and Appendix A, Standard Properties.
Verify that the scalable application resource has been added and validated.
# scrgadm -pv -j resource
This example shows the addition of a resource (resource-1) to a resource group (resource-group-1). Note that resource-group-1 depends on the failover resource group that contains the network addresses that are in use (schost-1 and schost-2 in the following example). The resource depends on shared address resources (schost-1, schost-2), which must reside in one or more failover resource groups that you defined previously.
# scrgadm -a -j resource-1 -g resource-group-1 -t resource-type-1 \ -y Network_resources_used=schost-1,schost-2 \ -y Scalable=True # scrgadm -pv -j resource-1 (resource-group-1) Res name: resource-1 (resource-group-1:resource-1) Res R_description: (resource-group-1:resource-1) Res resource type: resource-type-1 (resource-group-1:resource-1) Res resource group name: resource-group-1 (resource-group-1:resource-1) Res enabled: False (resource-group-1:resource-1) Res monitor enabled: True
After you add a scalable application resource, follow the procedure How to Bring Online Resource Groups to enable the resource.
Adding a resource causes the Sun Cluster software to validate the resource. If the validation fails, the scrgadm command prints an error message and exits. To determine why the validation failed, check the syslog on each node for an error message. The message appears on the node that performed the validation, not necessarily the node on which you ran the scrgadm command.
