Preface

This book describes the dynamic reconfiguration (DR) feature on the Sun Fire 15K system. DR enables you to attach system boards to, and detach them from, Sun Fire 15K domains while the operating environment continues to run.

Before You Read This Book

This book is intended for the Sun Fire 15K system administrator who has a working knowledge of UNIX® systems, particularly those based on the Solaris trademark operating environment. If you do not have such knowledge, first read the Solaris user documentation provided with this system, and consider UNIX system administration training.

Chapter 1 describes the functional limitations that you must observe in this version of the DR software.

Chapter 2 gives an overview of DR on the Sun Fire 15K

Chapter 3 describes all the possible conditions and states in which system boards, board slots, and components can be before, during, and after DR operations.

Chapter 4 provides an overview of DR operations performed on Sun Fire 15K domains.

Chapter 5 describes commands and options that are available on Sun Fire 15K domains.

Chapter 6 describes the steps you take to perform DR operations from Sun Fire 15K domains using the cfgadm(1M) command.
