Edition Date Software Version --------------------------------------------------------------------------------------- First Edition October 1989 A.30.00 Second Edition April 1990 A.40.00 Third Edition December 1990 B.30.00 Fourth Edition June 1992 B.40.00 Fifth Edition April 1994 C.50.00 Preface MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers. In HP documentation and in talking with HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories). Finally, you may encounter references to MPE V, which is the operating system for HP 3000s, not based on the PA-RISC architecture. MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as compatibility mode. The Performing System Management Tasks manual is an introduction to managing the 900 Series HP 3000 computer systems. It explains procedures and processes that the system manager uses to perform daily tasks. Defining Hardware to the System The system manager is typically the person who puts together the computer hardware to make it an operational unit or system. This person is responsible for defining peripheral units (printers, tape drives, disk drives, and terminals) to the operating system software, which then controls and operates the hardware. The system manager uses two software products to define peripherals: * The system generator (SYSGEN) * The network manager (NMMGR) Both of these products are delivered with your computer system. Tasks and Procedures This manual is written in a task format. To perform a task, simply look it up in the table of contents or in the index, turn to that section, read the introduction and follow the steps and examples. How to Get Started This manual is a companion to the Performing System Operations Tasks manual. You should review the Table of Contents in that manual to familiarize yourself with system operations and understand the relationship between operations and system management. In This Book This manual is your guide to the system manager tasks for the 900 Series HP 3000. Chapter 1 Starting the System explains the different ways to start your computer, how to install a new operating system, and how to use the initial system loader's standalone utilities. Chapter 2 Getting Started Defining Your System explains how to use SYSGEN to configure your system and introduces the other configurators (which are fully explained in the chapters that follow.) Chapter 3 Defining Input/Output Devices to the System explains how to use the IO configurator to get information about the current configuration and how to add devices to the system. Chapter 4 Defining Events to be Recorded explains how to use the LOG configurator to set which system and user activities your computer records. Chapter 5 Changing System Libraries, Programs, and Message Catalogs explains how to use the SYSFILE configurator to add or delete items on the system load tape. Chapter 6 Defining Miscellaneous System Resources explains how to use the MISC configurator to define limits on system resources, jobs and sessions. Chapter 7 Using Threshold Manager explains how to use the Threshold Manager utility, which alerts the system manager when certain internal operating system resources reach critical levels of utilization that can lead to a system abort. Chapter 8 Allowing Access to the System describes MPE's account structure and explains how to create new accounts, groups and users, and how to secure disk files. Chapter 9 Managing Disks describes disk management tasks for a 900 Series HP 3000 computer system. It explains the procedures for creating master or member volumes, setting limits on permanent and transient disk storage, and determining the amount of free disk space. Chapter 10 Planning Your Backup Strategy discusses how to choose a backup strategy including which type of backup to use and when to use it. Chapter 11 Shutting Down the System tells you when to shut down your system and gives you a step-by-step shutdown sequence. Chapter 12 System Hardware Descriptions presents an overview of the hardware of the 900 Series HP 3000 computer. Glossary defines the important terms introduced in system management. Index is an alphabetical listing of subjects, cross-referenced with their location in the manual. This manual contains information subject to change without notice. Conventions UPPERCASE In a syntax statement, commands and keywords are shown in uppercase characters. The characters must be entered in the order shown; however, you can enter the characters in either uppercase or lowercase. For example: COMMAND can be entered as any of the following: command Command COMMAND It cannot, however, be entered as: comm com_mand comamnd italics In a syntax statement or an example, a word in italics represents a parameter or argument that you must replace with the actual value. In the following example, you must replace filename with the name of the file: COMMAND filename bold italics In a syntax statement, a word in bold italics represents a parameter that you must replace with the actual value. In the following example, you must replace filename with the name of the file: COMMAND(filename) punctuation In a syntax statement, punctuation characters (other than brackets, braces, vertical bars, and ellipses) must be entered exactly as shown. In the following example, the parentheses and colon must be entered: (filename):(filename) underlining Within an example that contains interactive dialog, user input and user responses to prompts are indicated by underlining. In the following example, yes is the user's response to the prompt: Do you want to continue? >> yes { } In a syntax statement, braces enclose required elements. When several elements are stacked within braces, you must select one. In the following example, you must select either ON or OFF: COMMAND { ON } { OFF} [ ] In a syntax statement, brackets enclose optional elements. In the following example, OPTION can be omitted: COMMAND filename [OPTION] When several elements are stacked within brackets, you can select one or none of the elements. In the following example, you can select OPTION or parameter or neither. The elements cannot be repeated. COMMAND filename [ OPTION ] [ parameter] Conventions (continued) [...] In a syntax statement, horizontal ellipses enclosed in brackets indicate that you can repeatedly select the element(s) that appear within the immediately preceding pair of brackets or braces. In the example below, you can select parameter zero or more times. Each instance of parameter must be preceded by a comma: [,parameter][...] In the example below, you only use the comma as a delimiter if parameter is repeated; no comma is used before the first occurrence of parameter: [parameter][,...] |...| In a syntax statement, horizontal ellipses enclosed in vertical bars indicate that you can select more than one element within the immediately preceding pair of brackets or braces. However, each particular element can only be selected once. In the following example, you must select A, AB, BA, or B. The elements cannot be repeated. { A} |...| { B} ... In an example, horizontal or vertical ellipses indicate where portions of an example have been omitted. In a syntax statement, the space symbol shows a required blank. In the following example, parameter and parameter must be separated with a blank: (parameter) (parameter) The symbol indicates a key on the keyboard. For example, RETURN represents the carriage return key or Shift represents the shift key. CTRLcharacterCTRLcharacter indicates a control character. For example, CTRLY means that you press the control key and the Y key simultaneously.
