Dynamic Reconfiguration
Dynamic reconfiguration (DR) software is part of the Solaris Operating System. With
the DR software you can dynamically reconfigure system boards and safely remove
them or install them into a server while the Solaris Operating System is running and
with minimum disruption to user processes running on the system. You can use DR
to do the following:
■
Minimize the interruption of system applications while installing or removing a
board.
■
Disable a failing device by removing it before the failure can crash the operating
system.
■
Display the operational status of boards.
■
Initiate system tests of a board while the system continues to run.
