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.

To complete this procedure, you must supply the following information.

• the name of the failover resource group into 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

See the scrgadm(1M) man page for additional information.

Perform this procedure from any cluster node.

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 the failover resource group created previously.

   -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 depend on the particular data service. See the chapter for each data service to determine whether the data service requires this property.

   -y Standard_property=value, …

   Specifies a comma-separated list of standard properties that depends on the particular data service. See the chapter for each data service and Appendix A, Standard Properties to determine whether the data service requires this property.

   Note –

   You can set additional properties. See Appendix A, Standard Properties and the chapter in this book on how to install and configure your failover data service for details.

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

   # scrgadm -pv -j resource

   Adding the resource causes the Sun Cluster software to validate the resource. If the validation succeeds, you can enable the resource, and you can move the resource group into the state where the RGM manages it. If the validation fails, the scrgadm command produces an error message and exits. If the validation fails, 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.

Example – 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
