Edit: More good information when you do not know where to start.

The IBM Knowledge Center has a number of documents on problem analysis for AIX, Linux and more. While this information may seem basic to anyone’s who’s spent years dealing with these types of issues, junior admins should spend some time with beginning problem analysis, and all of the other info linked in this document.
The doc on AIX and Linux Problem Analysis starts with these tips: Remember the following points while troubleshooting problems:
- Has an external power outage or momentary power loss occurred?
- Has the hardware configuration changed?
- Has system software been added?
- Have any new programs or program updates (including PTFs) been installed recently?
There are also tutorials on IBM i problem analysis and light path diagnostics on Power Systems.
Finally, there’s a problem reporting form.
