Problem determination tips
Due to the variety of hardware and software combinations
that can be encountered, use the following infor m ation to
assist you in problem determination. If possible, have this
information available when requesting assistance from Ser-
vice Support and Engineering functions.
• Machine type and model
• Processor or hard disk upgr ades
• Failure symptom
— Do diagnostics f ail?
— What, when, wher e, single, or multiple systems?
— Is the failure repeatable?
— Has thi s configuration ever worked?
— If it has been working, what changes were made
prior to it failing?
— Is this the original reported failure?
• Reference/Diagnostics version
— Typ e an d ve r s ion lev el
• Hardware configuration
— Print (print screen) configuration currently in use
— BIOS level
• Operating system software
— Typ e an d ve r s ion lev el
Note: To elim inat e co nfus io n, id en tic al syst e m s are con si d-
ered identical only if they:
1. Are the exact ma chine type and models
2. Have the same B IOS level
3. Have the same adapters/attachments in the
same locations
4. Have the same address jumpers/termina-
tors/cabling
5. Have th e same software v ersions and lev els
6. Have the same Reference/Diagnostics Diskette
(version)
7. Have the same configuration options set in the
system
8. Have th e same setup for the op era tion system
control files
Comparing the configu ration an d softwa re se t-up
between "w orki ng and non-working" systems will
often lead to problem resolution.
