About This Guide

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

Audience

This guide is intended only for system administrators. As an 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 familiar with all the procedures necessary to maintain a UNIX system for high availability. This guide is not intended to train administrators or to plan the installation of a UNIX system.

Note

This guide describes only the administration of the operating system on an AlphaServer processor and devices that are local to the processor, such as single-spindle disks. 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 Documents for resources on the Web.

New and Changed Features

If you are updating your system from an older version of the UNIX operating system, you might 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 resources are available:

New features are added to many of the operating system's administrative commands and utilities. Command examples and procedures throughout the guide 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 guide.

The following administrative reference pages are updated with no impact on the content of this guide:

Where reference page revisions have impact in this guide, New and Changed Features by Chapter identifies the revised commands and utilities with their related chapter. This table has the following key:

See Organization for a list of chapter titles and a description of their content.
