Service IP labels and IP addresses

A service IP label is used to establish communication between client nodes and the server node. Services, such as a database application, are provided using the connection made over the service IP label.

A service IP label can be placed in a resource group as a resource that allows PowerHA® SystemMirror® to monitor its health and keep it highly available, either within a node or, if IP address takeover is configured, between the cluster nodes by transferring it to another node in the event of a failure.
