Connection and Configuration

There are four main types of DR operations:

Connection: in this operation, the slot provides power to the board and begins monitoring the board temperature.

Configuration: the operating system assigns functional roles to a board and loads device drivers for the board and for devices attached to the board.

Unconfiguration: the system detaches a board logically from the operating system and takes the associated device drivers offline. Environmental monitoring continues, but any devices on the board are not available for system use.

Disconnection: the system stops monitoring the board and power to the slot is turned off.

If a system board is in use, before powering it off and removing it, stop its use and unconfigure it. After a new or upgraded system board is inserted and powered on, connect its attachment point and configure it for use by the operating system.

cfgadm can connect and configure (or unconfigure and disconnect) in a single command, but if necessary, each operation (connection, configuration, unconfiguration, or disconnection) can be performed separately.
