You can specify the following node list properties when configuring data services.
The installed_nodes property is a property of the resource type for the data service. This property is a list of the cluster node names on which the resource type is installed and enabled to run.
The nodelist property is a property of a resource group. This property specifies a list of cluster node names where the group can be brought online, in order of preference. These nodes are known as the potential primaries or masters of the resource group. For failover services, configure only one resource group node list. For scalable services, configure two resource groups and thus two node lists. One resource group and its node list identify the nodes on which the shared addresses are hosted. This list is a failover resource group on which the scalable resources depend. The other resource group and its list identify nodes on which the application resources are hosted. The application resources depend on the shared addresses. Therefore, the node list for the resource group that contains the shared addresses must be a superset of the node list for the application resources.
The auxnodelist property is a property of a shared address resource. This property is a list of physical node IDs that identify cluster nodes that can host the shared address but never serve as primary in the case of failover. These nodes are mutually exclusive with the nodes that are identified in the node list of the resource group. This list pertains to scalable services only. For details, see the scrgadm(1M) man page.
