Chapter 3. Maintenance Analysis Procedures (MAPs)
This chapter contains maintenance analysis procedures (MAPs) for the Models 25F/80,
256/F0, and 256/F1 systems.
Entry MAP
Use the following table to determine your starting point.
When possible, run online diagnostics in service mode. Online diagnostics perform
additional functions, compared to standalone diagnostics. This ensures that the error
state of the system is captured in NVRAM for your use in fixing the problem. The AIX
error log and SMIT are only available when diagnostics are run from the hard drive.
Notes:
1. If more than eight digits are displayed in the top line of the operator panel display,
use only the first eight digits to find the error in the tables. The digits that display
beyond the first eight digits are location codes that can assist you in diagnosing the
problem. See “AIX and Physical Location Code Reference Tables” on page 20.
2. Licensed programs frequently rely on system information stored on the VPD module
on the operator panel assembly. If the MAPs indicate that the operator panel
assembly should be replaced, swap the VPD module from the old operator panel to
the new one. If the old VPD module has to be replaced, call technical support for
recovery instructions. If recovery is not possible, notify the system owner that new
keys for licensed programs may be required.
3. If a network adapter or the system board is replaced, the network administrator
must be notified so that the client IP addresses used by the server can be changed.
In addition, the operating system configuration of the network controller may need to
be changed in order to enable system startup. Also check to ensure that any client
or server that addresses this system is updated.
4. If you are servicing an SP system, go to the start of ″Call MAP 100″ in the
RS/6000
SP Systems Service Guide
, order number GA22-7442.
5. If you are servicing a clustered Eserver system, go to the start of ″Call MAP 100″
in the
Clustered Eserver Installation and Service Guide , order number SA22-7863.
Symptom Starting Point
You have a problem that does not prevent the
system from booting.
Go to the
Fast Path MAP in Diagnostic
Information for Multiple Bus Systems
.
You do not have a symptom. Go to
MAP 0020: Problem Determination
Procedure
in the Diagnostic Information for
Multiple Bus Systems
.
You have an SRN. Go to the
Fast Path MAP in the Diagnostic
Information for Multiple Bus Systems
.
The system stops and a 3-digit number is
displayed in the operator panel display.
Record SRN 101-xxx, where xxx is the 3-digit
number displayed in the operator panel display,
then go to the
Fast Path MAP in the Diagnostic
Information for Multiple Bus Systems
.
