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 storage 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 B-1.

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 6-1 on page 6-2 and the 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 6-1 on page 6-2 for a replacement decision.
