During boot up of a partitioned system, there is a global initialization phase where one of the system
processors is in control and initializing all of the system resources. During this phase, Exxx codes will be
displayed on both the physical operator panel and the HMC managed-system object. After the global
initialization phase completes, "LPAR..." is displayed on the physical operator panel and the HMC
managed-system object.
Each logical partition also has a partition initialization phase where one of the system processors assigned
to that partition is initializing all the resource of that partition. Exxx codes will be displayed on the virtual
terminal of the HMC logical partition object during this partition initialization phase.
Codes that may appear in the service processor boot progress log, the operating system error log, the
virtual terminal, and the operator panel display are as follows:
Checkpoints Checkpoints display in the operator panel from the time ac power is connected to the
system until the operating system login prompt is displayed after a successful operating
system boot. These checkpoints have the following forms:
8xxx
9xxx
Exxx
0xxx
and
2xxx
Error Codes If a fault is detected, an 8-digit error code is displayed in the operator panel display. A
location code may be displayed at the same time on the second line.
SRNs Service request numbers, in the form xxx-xxx or xxx-xxxx, may also be displayed on the
operator panel display and be noted in the AIX error log.
Note: If the running operating system is Linux, SRNs will not display in the Linux system
error log.
Checkpoints can become error codes if the system fails to advance past the point at which the code is
presented. For a list of the checkpoints, see Chapter 4, "Checkpoints", on page 353. Each entry provides a
description of the event and the recommended action if the system fails to advance.
SRNs are listed in the RS/6000 and Eserver pSeries Diagnostic Information for Multiple Bus Systems,
order number SA38-0509.

8xxx checkpoints are displayed from the time ac power is connected to the system
until the OK prompt is displayed by the service processor on the operator panel
display. (Several 9xxx checkpoints are displayed just before the OK prompt
displays.)
9xxx checkpoints are displayed by the service processor after the power-on
sequence is initiated. A system processor takes control when 91FF displays on the
operator panel display.
Note: Certain checkpoints may remain in the display for long periods of time. A
spinning cursor is visible in the upper-right corner of the display during
these periods to indicate that system activity is continuing.
Exxx checkpoints indicate that a system processor is in control and is initializing
the system resources. Control is being passed to the operating system when E105
displays on the operator panel display. Location code information may also display
on the operator panel during this time.
0xxx codes are AIX progress codes and configuration codes. Location codes may
also display on the operator panel display during this time.
Note: AIX progress codes will not display when the running operating system is
Linux.
