Preface

This Legato Storage Manager Administrator's Guide contains complete information for using Legato Storage Manager (LSM) as an Oracle data storage management system. It describes the initial configuration procedure for LSM. It then explains how to use LSM for managing Oracle backup devices and volumes, monitoring Oracle backup and restore operations, and managing Oracle backup data.

This preface contains these topics:

Audience

The information in this guide is for system administrators and Oracle database administrators (DBAs) who are responsible for maintaining Oracle Server backup and recovery systems. It includes information on configuring an Oracle data storage management system for Oracle9i level servers on Windows 2000 or Windows NT.

You need a working knowledge of Oracle concepts and terminology, especially as related to Oracle database backup and recovery, to use this guide effectively. This guide does not include LSM installation instructions. For information about installing LSM, refer to the Oracle Server Installation Guide for your Windows system.

Organization

The Legato Storage Manager Administrator's Guide has five chapters and three appendixes, followed by a glossary and an index. The first two chapters introduce you to LSM and its major features. They describe how to properly configure LSM to work with the other components of a complete Oracle backup and recovery system. Chapters 3 through 5 contain details about how to use LSM to manage Oracle backups and recoveries as well as the devices and volumes used during the Oracle backup and restore operations. Additional information relating to running LSM is contained in the appendices.

This document contains:

Chapter 1, "Introduction"

This chapter surveys the main features of LSM and how they compare with the features of the Legato NetWorker^® upgrade product. It explains how LSM functions with other major components of an Oracle9i backup and recovery system.

Chapter 2, "Preparing to Use LSM"

This chapter provides a more detailed view of the internal LSM organization of resources and attributes and how they are used during Oracle backup and restore operations. It also includes information about the proper configuration of LSM resources.

Chapter 3, "Media Management"

This chapter focuses on the procedures for configuring and managing the storage devices and volumes LSM uses for Oracle backup and restore operations. It explains how LSM uses volume pools to sort the Oracle storage volumes and describes the system that LSM uses to manage the life cycle of the data backed up to those volumes.

Chapter 4, "Backup and Restore Operations"

This chapter provides information about using LSM for Oracle backup and restore operations, after you have configured the required LSM Server resources. It covers the methods for running Oracle backups and restores, including the LSM Server bootstrap backups that are essential for disaster recovery. This chapter also outlines the procedures for monitoring Oracle backups and restores by means of the LSM Administrator GUI and specific log files.

Chapter 5, "Disaster Recovery"

This chapter describes different types of system disasters on your LSM Server and how to recover from them. It stresses the importance of preparing for a disaster.

Appendix A, "Scanner"

This appendix describes how to use the scanner program to re-create client file index entries or re-create media database entries, if no entries for a storage volume exist in the media file.

Appendix B, "Client Server Communications"

Many of the problems that LSM users report when they set up and configure LSM are actually problems with the communications in their networks. This appendix contains a procedure for testing the communications in the network.

Appendix C, "Using Label Templates"

LSM labels (initializes) each storage volume with a unique internal label that corresponds to a pool. During backup and other operations, LSM can identify the pool to which a volume belongs by its label. LSM applies a label template to create a unique internal label for each volume. This appendix discusses the setup and use of label templates.

Conventions

Because UNIX is case-sensitive, conventions in this document may differ slightly from those used in Oracle product documentation.

The following conventions apply to text in this guide:

`monospace`	Monospace type indicates Windows command-line commands, directory names, pathnames, and filenames.
brackets [ ]	Words enclosed in brackets indicate key names (for example, Press [Return]). Note that brackets have a different meaning when used in command syntax.
italics	Italic type indicates a variable, including variable portions of filenames, document titles, or emphasis.
UPPERCASE	Uppercase letters indicate Structured Query Language (SQL) statements, initialization parameters, or environment variables.

Command syntax is shown in monospace font in this guide. The following conventions apply to command syntax:

backslash \	A backslash indicates a command that is too long to fit on a single line. Enter the line as printed (with a backslash) or enter it as a single line without a backslash: `dd if=/dev/rdsk/c0t1d0s6 of=/dev/rst0 bs=10b \ count=10000`
braces { }	Braces indicate required items: `.DEFINE {macro1}`
brackets [ ]	Brackets indicate optional items: `cvtcrt` termname `[`outfile`]` Note that brackets have a different meaning when used in regular text.
ellipses ...	Ellipses indicate an arbitrary number of similar items: `CHKVAL fieldname` value1 value2 ... valueN
italics	Italic type indicates a variable. Substitute a value for the variable: library_name
`monospace`	Monospace type indicates commands or text you type: `connect`
`monospace italic`	Monospace italic type indicates commands or text you type and need to substitute a variable: `nwadmin -s` `server-name`
vertical line \|	A vertical line indicates a choice within braces or brackets: SIZE filesize [K\|M]
