Preface

This document describes the Dynamic Reconfiguration (DR) feature, which enables you to service system boards without the need to reboot the system. With DR you can power down an individual board slot rather than the entire system. The commands and descriptions in this document apply to Sun(TM) Enterprise(TM) 3x00, 4x00, 5x00, and 6x00 systems.
