Dynamic Reconfiguration (DR)
The Dynamic Reconfiguration (DR) software is part of the Solaris OS. With DR you
can dynamically reconfigure CPU/Memory boards in order to safely remove them
or install them into a system while the Solaris OS is running. DR is performed with
minimum disruption to user processes running in the system.
The process of replacing a board while the system is still running is called hot-
plugging. DR provides this software hot-plug support. For more information on DR,
refer to Chapter 1, "Overview" and Chapter 9 "CPU/Memory Board Replacement
and Dynamic Reconfiguration (DR)" in the system administration manual.
