About This Manual

This manual describes how to configure and manage disk storage using the Logical Storage Manager (LSM) software. It includes information on LSM concepts and how to plan, set up, monitor, change, and troubleshoot an LSM configuration.

Audience

This manual is intended for system adminstrators who configure and manage storage devices under LSM control. To use this manual you must be able to administer a standalone system running the HP Tru64 UNIX operating system software and its storage devices, or a TruCluster Server running the HP Tru64 UNIX operating system software and its storage devices.

New and Changed Features

The following changes have been made to this manual since the Version 5.1A release:

Chapter 1 has been revised to better define LSM objects, including the new Fast Plex Attach log type.

Chapter 2 has been expanded to discuss planning considerations specific to a TruCluster Server environment.

Chapter 3 contains information on configuring LSM in a TruCluster Server environment. This information was previously included in the Cluster Administration manual.

Chapter 5 has been expanded to describe the new Fast Plex Attach feature for backing up volumes.

Chapter 6 has been revised to simplify the discussion of replacing failed disks and the subsequent volume recovery operations.

Chapter 7 describes special cases in LSM management, including upgrading from a Version 4.0 system and uninstalling the LSM software.

The following chapters and appendixes have been removed:
- Former Chapter 7 — Error Messages
- Appendix C — Using the voldiskadm Menu Interface
- Appendix D — The Visual Administrator Interface (dxlsm)
- Appendix E — Using the Visual Administrator Interface
Information on the interfaces previously documented in these appendixes is available in the reference page for the relevant interface. For more information, see voldiskadm(8) and dxlsm(8X).

Organization

This manual is organized as follows:

Chapter 1	Describes LSM features, terms, and concepts, and introduces the available interfaces to LSM.
Chapter 2	Presents factors to consider in planning your LSM configuration, describes how to find unused storage devices to use with LSM, and provides worksheets to aid you in planning LSM volumes and disk groups.
Chapter 3	Describes how to install and initialize LSM as part of a system or cluster upgrade (from Version 5.0 or higher to the current version) or as part of a full installation.
Chapter 4	Describes how to create new LSM disks, disk groups, and volumes, how to configure UFS file systems and AdvFS domains to use LSM volumes for their storage, and how to place existing data under LSM control.
Chapter 5	Describes common management tasks for LSM objects.
Chapter 6	Describes how to identify and recover from problems and how to replace failed disks under LSM control.
Chapter 7	Describes special cases in LSM management, such as upgrading a system with an existing LSM configuration from Version 4.0 to the current version, moving disk groups between systems, and removing (uninstalling) the LSM software from a single system or a cluster.
Appendix A	Describes how to start the Storage Administrator GUI and how to manage LSM objects using this interface.
Appendix B	Describes how to track Storage Administrator activities, how to use the Storage Administrator GUI, and how to customize the Storage Administrator GUI.

Icons on Tru64 UNIX Printed Manuals

The printed version of the Tru64 UNIX documentation uses letter icons on the spines of the manuals to help specific audiences quickly find the manuals that meet their needs. (You can order the printed documentation from HP.) The following list describes this convention:

G	Manuals for general users
S	Manuals for system and network administrators
P	Manuals for programmers
R	Manuals for reference page users

Some manuals in the documentation help meet the needs of several audiences. For example, the information in some system manuals is also used by programmers. Keep this in mind when searching for information on specific topics.

The Documentation Overview provides information on all of the manuals in the Tru64 UNIX documentation set.
