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

Note: 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 conﬁguration options set in the system

7. Have the same setup for the operation system control ﬁles

Comparing the conﬁguration and software set-up between

“working and non-working” systems will often lead to problem

resolution.
