Problem determination tips

Due to the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions.

Machine type and model

Processor or hard disk upgrades

Failure symptom

Do diagnostics indicate a failure?

What, when, where, single, or multiple systems?

Is the failure repeatable?

Has this configuration ever worked?

If it has been working, what changes were made prior to it failing?

Is this the original reported failure?

Diagnostics version

Type and version level

Hardware configuration

Print (print screen) configuration currently in use

BIOS level

Operating system software

Type and version level

Notes: To eliminate confusion, identical systems are considered identical only if they:

1.Are the exact machine type and models

2.Have the same BIOS level

3.Have the same adapters/attachments in the same locations

4.Have the same address jumpers/terminators/cabling

5.Have the same software versions and levels

6.Have the same Diagnostic Diskettes (version)

7.Have the same configuration options set in the system

8.Have the same setup for the operating system control files

Comparing the configuration and software set-up between “working and non-working” systems will often lead to problem resolution.
