The DR software package enables a service provider to safely add, remove, or modify some types of system hardware while the system is still running.
You can use DR commands to:
Shorten the interruption of system applications while installing or removing a board
Disable a failing device by removing it from the logical configuration, before the failure can crash the operating system
Display the operational status of boards in a system
Initiate system tests of a board while the system continues to run
Reconfigure a system while the system continues to run
Invoke hardware-specific functions of a board or a related attachment
This release of DR uses a command-line user interface. The primary command for Dynamic Reconfiguration is the configuration administration program cfgadm. Refer to the cfgadm(1M) man page for further details.
