About This Manual

This manual describes the tasks you perform to administer the Tru64 UNIX operating system running on an AlphaServer.

Audience

This manual is intended only for system administrators. As a system administrator, you should have knowledge of the UNIX operating system concepts and commands and the supported hardware and software configurations. You must be trained in the operational aspects of UNIX system administration and be familiar with all the procedures necessary to maintain a UNIX system for high availability. This manual is not intended to train system administrators or to plan the installation of a UNIX system.

New and Changed Features

The following changes were made to this manual:

• Chapter 5 is a subset of the previous version of this chapter. The removed material has been incorporated into the Hardware Management manual.

• Chapter 8 has been updated to focus on printer configuration using TCP/IP. This chapter also describes the updated lprsetup procedure and describes new lpc commands.

• Section 9.7.5 has been updated.

• Section 11.3 has been updated with a discussion of environmental monitoring from the command line, as part of HP Insight Manager, and using sensor monitoring (which is available on a limited number of recent hardware platforms).

• Chapter 13 has been updated for discussions on starting and stopping the Event Manager, configuration for preventing missed events, remote authentication, remote logging, and the increased message capacity of event connections.

• Chapter 14 now includes a description of the graphical user interfaces for configuring crash dumps for your needs and to save a snapshot of system memory to a dump file.

If you are updating your system from an older version of the UNIX operating system, you may want to review all the changes that were implemented in the intervening releases. You can find this information in the HTML files provided on the Software Documentation CD-ROM, especially New and Changed Features from Previous Releases. In addition, the following online resource isavailable:

• Previous versions of this manual are available on the World Wide Web at: http://www.tru64unix.compaq.com/docs/

  See the New and Changed features section of those versions to learn the evolution of this manual.

  Also, you can obtain technical updates for any information that is not included in the documentation provided with your media.

New features are added to many of the operating system's administrative commands and utilities. Command examples and procedures throughout the manual are verified to ensure that they are correct. In several cases, the related reference pages are revised completely. Some information is relocated to reference pages to eliminate redundancy and reduce the size of this manual.

Organization

This manual is organized as follows:

Related Documentation

The following documents provide important information that supplements the information in certain chapters:

• The Installation Guide and Installation Guide — Advanced Topics describe how to install your operating system. Several important administrative tasks, such as installing software and installation cloning, are described in detail in these manuals.

• The Hardware Management manual is the companion manual to this manual. The Hardware Management manual describes the tasks you must perform to maintain system hardware that is controlled by the Tru64 UNIX operating system.

• For important information on storage configurations, including the configuration and maintenance of storage arrays, see your StorageWorks documentation. You use StorageWorks software applications, such as the StorageWorks Command Console (SWCC) in addition to the utilities provided by the operating system. See Related Documentation for resources on the Web.

• The Network Administration: Services and Network Administration: Connections manuals describe how to set up, configure, and troubleshoot your network.

• The Advanced Server for UNIX (ASU) Concepts and Planning Guide and Installation and Administration Guide provide information on administering Windows domain accounts and sharing printers with PC users. These documents are supplied with the ASU software on the Associated Products CD-ROM, Volume 2.

• The Security Administration manual provides information on security that affects account management and file system sharing.

• The AdvFS Administration and Logical Storage Manager manuals provide information on advanced file systems and storage management.

• The System Configuration and Tuning manual provides information on system performance tuning and advanced kernel configuration.

• The Release Notes provide important information such as restrictions on using certain operating system features.

Many procedures described in this manual concern the administration of system hardware and peripherals such as storage devices. See the owner's manual for any hardware device, particularly if you need information on using software that is supplied with, or required to manage the device.

Use the console commands for your processor; they are documented in the owner's manual. The Release Notes provide information on device-specific restrictions. The following online resources are available:

• You can find hardware documentation at the Alpha Systems Technology web site, located at the following URL: http://www.compaq.com/alphaserver/technology/index.html

• You can find software and drivers, including Alpha firmware downloads at the following URL: http://www.compaq.com/support/files

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:

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.
