Device Configuration Manager Overview

The Configuration Manager is a rule-driven program that automatically configures devices in the system during system boot and run time. When the Configuration Manager is invoked, it reads rules from the Configuration Rules object class and performs the indicated actions.

For more information on Configuration Rules, see Configuration Rules (Config_Rules) Object Class in AIX® Version 6.1 Technical Reference: Kernel and Subsystems Volume 2.

Devices in the system are organized in clusters of tree structures known as nodes. Each tree is a logical subsystem by itself. For example, the system node consists of all the physical devices in the system. The top of the node is the system device. Below the bus and connected to it are the adapters. The bottom of the hierarchy contains devices to which no other devices are connected. Most pseudo-devices, including low -function terminal (LFT) and pseudo-terminal (pty) devices, are organized as separate tree structures or nodes.
