Problem Solving and Troubleshooting in AIX 5L - IBM Redbooks

Preface
This redbook covers problem determination and troubleshooting on the IBM
^ pSeries and RS/6000 platform. It is intended as a guide to the
approach that should be adopted when attempting to resolve a problem on an
IBM ^ pSeries and RS/6000 system running AIX 5L Version 5.1. It is not
intended to replace the comprehensive documentation available for the AIX
operating system or the System Installation and Service Guides available for IBM
^ pSeries and RS/6000 system hardware. Instead, it should be
considered as a useful supplement to guide you through the problem
determination process.
A problem can manifest itself in many ways, and very often the root cause of the
problem is not obvious. This redbook describes an approach to problem
determination that will guide you through the initial steps in problem diagnosis
and to narrow down and identify the component or subsystem that is
experiencing a problem.
In addition to helping you determine the likely cause of your problem, this
redbook describes some of the most common problems that can occur with AIX
systems and, where possible, describes the actions you can take to resolve
them.
This redbook is a valuable tool for system administrators and other technical
support personnel who deal with RS/6000 and AIX problems.
The information in this redbook is not intended to completely cover problem
determination on SP systems or systems configured as nodes in an HACMP
cluster. This redbook does not cover Itanium TM -based systems (IA-64),
although many items will be true for both POWER and Itanium-based systems.
The team that wrote this redbook
This redbook was produced by a team of specialists from around the world
working at the International Technical Support Organization, Austin Center.
