OpenVMS Systems Operations Guide: VAX 8820,30,40 Systems

This document, the "OpenVMS Systems Operations Guide," serves as a quick reference for basic system operations on VAX 8820, 8830, and 8840 systems. It is primarily intended for system software support, Digital Services, system managers, and participants in OpenVMS training courses.

The guide covers:

1. Console Subsystem Overview: Describes the components (MicroVAX II with control panel, console terminal, fixed disk, tape drive), their use in system control (examining data, stopping processors, booting), and methods for tracking system operations (console log files and printers).
2. System Operations: Details procedures for both orderly system shutdowns (using SHUTDOWN.COM) and emergency shutdowns (using CRASH.COM when the system is hung, which generates a dump file for analysis).
3. Console Commands: Explains the various console prompts (indicating system state) and outlines common commands used to power on the system, boot it, obtain system status information, and configure automatic booting and restart behaviors (e.g., BOOT, HALT, POWER, ENABLE/DISABLE AUTO BOOT/RESTART/POWERON).
4. System Boot Procedures: Describes how to boot the OpenVMS operating system using command procedures (like DEFBOO.CMD), including booting from different system disks or directories, and performing conversational boots to modify system parameters (SYSGEN).
5. Backup Procedures: Introduces the "Standalone BACKUP" utility, emphasizing its importance for system disk integrity during upgrades, against accidental file deletion, disk malfunctions, and for defragmentation. It details how to install and boot Standalone BACKUP from either the system disk or the console fixed disk.
