Starting Point for All Problems
Before you start problem analysis, review the “System Service Library Structure”
on page 3 and how the system and its devices connect together (see “System
Architecture and Configuration” in the iSeries Service Functions information). Also
review the system reference code (SRC) definition and formats and how they
appear (see “System Reference Code (SRC) Record” in the
iSeries Service Functions
information). Also understand how the control panel works (see “Control Panel
Functions” in the
iSeries Service Functions information). Also, review any
supplemental RPQ pages in this guide.
