Problem analysis procedures
You can often solve problems that occur on your system with methodical analysis.
If you need the help of a service representative, you need to offer sufficient information to that person.
Things to keep in mind while troubleshooting problems
- Has there been an external power outage or momentary power loss?
- Has the hardware configuration changed?
- Has system software been added?
- Have any new programs or program changes been recently installed?
To make sure that your licensed programs and products have been correctly installed, use the Check Product Option (CHKPRDOPT) command.
- Have any system values changed?
- Has any system tuning been done?
After considering this information, you are ready to begin problem analysis.
