Chapter 2. Diagnostic Overview
The system uses an integrated set of software diagnostic procedures to help isolate failing components
and system maintenance. This book, along with the
RS/6000
Eserver
pSeries Diagnostic Information for
Multiple Bus Systems
, is the basis of the diagnostic procedures for the system. In particular, Chapter 4,
“Checkpoints”, on page 159, Chapter 5, “Error Code to FRU Index”, on page 209, Chapter 6, “Using the
Online and Standalone Diagnostics”, on page 353, and Chapter 10, “Parts Information”, on page 515, in
this book are important for the trained service representative to understand and use when isolating a
failure on the system.
The manufacturer recommends that systems configured with 4 GB of memory or greater have access to a
4-mm or 8-mm tape drive for submission of system dump information if required. This function can be
accomplished through locally attached or network-attached devices, as appropriate.
Maintenance Analysis Procedures (MAPs)
Maintenance Analysis Procedures (MAPs) guide the trained service representative through the system.
These MAPs are the entry point for all isolation and error recovery procedures. The MAPs are consistent
with existing procedures and methods. The system uses a set of integrated procedures, mentioned earlier,
to which the MAPs are the primary entry point.
The MAPS are as follows:
v
Entry MAP
v
Quick Entry MAP
v
MAP 1020: Problem Determination MAP
v
MAP 1240: Memory Problem Resolution
v
MAP 1321: Quick Entry MAP for Systems with Service Focal Point. This MAP contains information for
systems not running under the AIX operating system.
v
MAP 1322: End of Call MAP for Systems with Service Focal Point
v
MAP 1520: Power MAP
v
MAP 1521: The Base System Drawer will not Power On and No Error Codes are Available
v
MAP 1522: Cannot Power On the I/O Drawer, Power Present LED Does Not Come On
v
MAP 1523: The SPCN Error Codes Table Directed You Here and the Error Code is 1011 1B0x
v
MAP 1540: Problem Isolation Procedures
v
MAP 1541: JTAG Problem Isolation
v
MAP 1542: I/O Problem Isolation
v
MAP 1548: Processor Subsystem Problem Isolation
The Entry Map is the starting point for problem determination. The purpose of this MAP is to quickly point
to the appropriate MAP or service reference information either in this book, or in the common book set,
which includes the
RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems
and
PCI
Adapter Placement Reference
.
The Quick Entry MAP is a subset of the Entry MAP and helps to save time for some types of problems.
The Problem Determination MAP provides a structured analysis method to get an error code if one is not
provided by the customer, or if diagnostics cannot be loaded.
The Power MAP deals with isolation of components to diagnose a power problem. Power problems can be
related to powering on and powering off the system, or power failures that occur after power is turned on.
