Universal Clustering Problem Determination Guide

Problem determination and problem solving on the RS/6000 SP and clusters can be difficult because the malfunction may imply the movement of several components within AIX and PSSP. Problem determination on the RS/6000 universal cluster is part of the daily tasks of a system administrator. Although the RS/6000 universal cluster is a very stable platform, the manner in which distributed and parallel environments are intermixed may cause certain problems that cannot be easily solved by someone with only AIX experience.

This IBM Redbook gives a comprehensive explanation of certain RS/6000 SP and cluster components and provides the reader with tools and procedures that can be used for problem isolation and problem solving in a cluster environment.

This redbook is oriented to RS/6000 SP and cluster professionals who install, configure, and administer universal cluster systems. Several procedures are outlined and tested, along with the explanation for the causes of common SP and cluster problems.

This universal clustering guide is the perfect companion for the RS/6000 SP and clusters product manuals when you need to identify and solve system problems.
