Chapter 6. Solving problems

This section contains information to help you solve some of the problems that you
might have with the storage subsystem or expansion enclosure. It describes the
problem indicators, error messages, and suggested actions.

Solving problems in the DS3500 storage subsystem

For instructions for obtaining service and technical assistance for the storage
subsystem and other IBM products, see Appendix B, “Getting help and technical
assistance,” on page 145.

Use the LEDs, the diagnostics and test information, the symptom-to-FRU index, and
the connected server

Hardware Maintenance Manual

or

Problem Determination and

Service Guide

to diagnose problems.

Use Table 9 on page 128 and the DS Storage Manager Recovery Guru to diagnose
storage subsystem problems and component failures and find solutions to problems
that have definite symptoms. Do not depend solely on Table 9 on page 128 for a
replacement decision.
