Read an Excerpt
This book is one of an on-going series of books collectively known as the SunBluePrints Program. The Boot Disk Management BluePrint focuses on the boot diskof the Solaris Operating Environment (OE) and serves as a replacement for theSun BluePrints book titled, Guide to High Availability, Configuring boot/ root/ swap.This book will explain how to select a boot device, partition and lay out a filesystem, select and use a volume manager, and recover from service events andoutages.
Sun BluePrints Program
The mission of the Sun BluePrints Program is to empower Sun's customers with thetechnical knowledge required to implement reliable, extensible, and secureinformation systems within the datacenter using Sun products. This programprovides a framework to identify, develop, and distribute best practices informationthat applies across the Sun product lines. Experts in technical subjects in variousareas contribute to the program and focus on the scope and usefulness of theinformation.
The Sun BluePrints Program includes books, guides, and online articles. Throughthese vehicles, Sun can provide guidance, installation and implementationexperiences, real-life scenarios, and late-breaking technical information.
The monthly electronic magazine, Sun BluePrints OnLine, is located on the Web athttp://www.sun.com/blueprints. To be notified about updates to the SunBluePrints Program, please register yourself on this site.
Who Should Read This Book
This book is primarily intended for system administrators, system/IT/enterprisearchitects, and integrators with moderate-to-advanced knowledge of the Solaris OEas well as basic knowledge of VERITAS Volume Manager (VxVM) or SolsticeDiskSuite software.
Before You Read This Book
You should be familiar with the basic administration and maintenance functions ofthe Solaris OE.
How This Book Is Organized
Chapters 1 through 3 of this book outline the boot process and installation methods,present methods for managing the on-disk operating system (OS), and introducetechniques for upgrading the Solaris OE.
Chapters 4 and 9 contain information about the reference configuration presented inthis book and methods for selecting and using logical volume managers (LVMs).Chapters 5 and 6 provide VxVM-specific information, while Chapters 7 and 8address Solstice DiskSuite software-specific issues. Read the appropriate chapters forinformation about the LVM in use at your site. Read Chapter 9 for best-practicerecommendations for implementing LVMs in your datacenter.
Chapter 1 "Partitioning Boot Disks," examines the basics of boot disk selection,layout, and partitioning.
Chapter 2 "Managing On-Disk OS Images," provides best practices andrecommendations for managing the on-disk OS image. It includes recommendationsfor installing, maintaining, and patching the Solaris OE with or without an LVMmanaging the boot disk.
Chapter 3 "Managing Solaris Operating Environment Upgrades," introduces LiveUpgrade (LU) and provides best practices for using LU to upgrade the Solaris OEwith minimal downtime and minimal impact to the user or applications. Mostimportantly, LU provides a safe and consistent fall-back environment in case anupgrade or software installation fails.
Chapter 4 "Configuring Boot Disks," presents a reference configuration of the rootdisk and associated disks that emphasizes the value of configuring a system for highavailability and high serviceability.
Chapter 5 "Configuring a Boot Disk With VERITAS Volume Manager," presentsmethodologies for designing and implementing a highly reliable, available, andserviceable (RAS) configuration for a VxVM-managed boot disk that emphasizessimplicity, consistency, resilience, and recoverability.
Chapter 6 "Maintaining a Boot Disk With VERITAS Volume Manager," presentstechniques for recovering and repairing a damaged VxVM-managed boot disk.
Chapter 7 "Configuring a Boot Disk With Solstice DiskSuite Software," presentsmethodologies for designing and implementing a highly reliable, available, andserviceable configuration for a Solstice DiskSuite software-managed boot disk thatemphasizes simplicity, consistency, resilience, and recoverability.
Chapter 8 "Maintaining a Boot Disk With Solstice DiskSuite Software," presentstechniques and procedures for recovering and repairing a damaged SolsticeDiskSuite software-managed boot disk.
Chapter 9 "Using Multiple Logical Volume Managers," addresses the use ofmultiple LVMs on the same system and strongly recommends that you implement asingle LVM on a system. Additionally, this chapter outlines several advantages tostandardizing on one LVM, including minimizing system complexity and speedingrecovery time.
