The procedures in this section enable you to perform the following tasks.
Configuring a cluster node to be an additional master of a resource group
Removing a node from a resource group
The procedures are slightly different, depending on whether you plan to add or remove the node to or from a failover or scalable resource group.
Failover resource groups contain network resources that both failover and scalable services use. Each IP subnetwork connected to the cluster has its own network resource that is specified and included in a failover resource group. The network resource is either a logical hostname or a shared address resource. Each network resource includes a list of PNM object that it uses. For failover resource groups, you must update the complete list of PNM objects for each network resource that the resource group includes (the netiflist resource property).
The procedure for scalable resource groups involves the following steps:
Repeating the procedure for failover groups that contain the network resources that the scalable resource uses
Changing the scalable group to be mastered on the new set of hosts
