What Is DR?

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.
