How to Add a Failover Application Resource to a Resource Group

A failover application resource is an application resource that uses logical hostnames that you previously created in a failover resource group.

Perform this procedure from any cluster node.

Before You Begin

Ensure that you have the following information.

• The name of the failover resource group to which you are adding the resource

• The name of the resource type for the resource

• The logical hostname resources that the application resource uses, which are the logical hostnames that you previously included in the same resource group

Steps

1. Become superuser on a cluster member.

2. Add a failover application resource to the resource group.

   # scrgadm -a -j resource -g resource-group -t resource-type \ [-x extension-property=value, …] [-y standard-property=value, …]

   -a

   Adds a resource.

   -j resource

   Specifies your choice of the name of the resource to add.

   -g resource-group

   Specifies the name of a failover resource group. This resource group must already exist.

   -t resource-type

   Specifies the name of the resource type for the resource.

   -x extension-property=value, …

   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.

   -y standard-property=value, …

   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. To determine which standard properties to set, see the documentation for the resource type and Appendix A, Standard Properties.

3. Verify that the failover application resource has been added and validated.

   # scrgadm -pv -j resource

Example 2–9 Adding a Failover Application Resource to a Resource Group

This example shows the addition of a resource (resource-1) to a resource group (resource-group-1). The resource depends on logical hostname resources (schost-1, schost-2), which must reside in the same 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,schost2 \
# 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

Next Steps

After you add a failover application resource, use the procedure How to Bring Online Resource Groups to enable the resource.

Troubleshooting

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.
