A failover resource group contains the following types of resources:
Network address resources, which are instances of the built-in resource types LogicalHostname and SharedAddress
Failover resources, which are the data service application resources for a failover data service
The network address resources and their dependent data service resources move between cluster nodes when data services fail over or are switched over.
Perform this procedure from any cluster node.
Become superuser on a cluster member.
Create the failover resource group.
# scrgadm -a -g resource-group [-h nodelist]
Adds the specified resource group.
Specifies your choice of the name of the failover resource group to add. This name must begin with an ASCII character.
Specifies an optional, ordered list of nodes that can master this resource group. If you do not specify this list, it defaults to all of the nodes in the cluster.
Verify that the resource group has been created.
# scrgadm -pv -g resource-group
This example shows the addition of a failover resource group (resource-group-1) that two nodes (phys-schost-1 and phys-schost-2) can master.
# scrgadm -a -g resource-group-1 -h phys-schost1,phys-schost-2 # scrgadm -pv -g resource-group-1 Res Group name: resource-group-1 (resource-group-1) Res Group RG_description: <NULL> (resource-group-1) Res Group management state: Unmanaged (resource-group-1) Res Group Failback: False (resource-group-1) Res Group Nodelist: phys-schost-1 phys-schost-2 (resource-group-1) Res Group Maximum_primaries: 1 (resource-group-1) Res Group Desired_primaries: 1 (resource-group-1) Res Group RG_dependencies: <NULL> (resource-group-1) Res Group mode: Failover (resource-group-1) Res Group network dependencies: True (resource-group-1) Res Group Global_resources_used: All (resource-group-1) Res Group Pathprefix:
After you create a failover resource group, you can add application resources to this resource group. See Adding Resources to Resource Groups for the procedure.
