ULTRIX-32 Guide to System Exercisers

This document, the "ULTRIX-32 Guide to System Exercisers," is a comprehensive manual designed for system managers and maintainers of the ULTRIX-32 operating system. It details how to use various system exercisers (diagnostic tools) for troubleshooting and maintaining system health.

The guide covers:

• General Operation: How to run exercisers, including requirements (superuser, /usr/field directory), using on-line help, managing diagnostic output and log files, and running multiple exercisers simultaneously (e.g., using syscript).
• File Systems and Memory: Exercisers for testing local file systems (fsx), system memory (memx), and shared memory (shmx).
• Peripherals: Exercisers for testing disk drives (dskx), tape drives (mtx), and line printers (lpx).
• Network and Communications Systems: Exercisers for testing TCP/IP networks (netx) and terminal communication systems (cmx).

Important caveats are provided throughout, such as the destructive nature of certain disk exerciser options (which can overwrite data), considerations for running exercisers in diskless environments, potential conflicts between different exercisers (e.g., fsx and dskx), and managing system resources like swap space when exercising memory. The document emphasizes the importance of reviewing error logs and diagnostic outputs for effective troubleshooting.
