If you use Operations Console (LAN), you must create a service host name (interface).
After the service host name (interface) is created, the server is ready to use the service tools server to support System i® Navigator functions, for example. However, you can have a network adapter for the service tools server when the console is something other than Operations Console (LAN). To do this, you need to configure the service host name (interface) so that the service tools server uses that connection.
With a configured network adapter available during an initial program load (IPL) procedure, the system activates the adapter that supports the console, but also activates the adapter used for the service host name, if different. In this scenario, you now have two resources in your system that might not be used by IBM® i, depending on your hardware. Conversely, if you previously had a service host name for System i Navigator and are now using Operations Console (LAN), you do not have to make any IP configuration changes because the same resource is used.
