Sun N1 Service Provisioning System User's Guide for SAP Plug-In 1.0

Creating and Managing Logical Hosts

A logical host name is the name given to an IP address that can be plumbed on a host machine. Later it can be unplumbed on the original host and plunbed on another host machine.

The Tasks page of the SAP plug-in enables you to create and manage logical hosts.
