Service Request Numbers (SRNs)
Service request numbers (SRNs) are generated by the error logging facility and by the
diagnostics. SRNs help you to identify the cause of a problem, the failing
field-replaceable units (FRUs), and the service actions that might be needed to solve
the problem.

Displaying SRNs

To see the SRNs run the Remote Systems Management (RSM) Configurator.
(see the

Installation and User Guide

for details of how to load and start the RSM
configurator)
Use the configurator to display the SRNs as follows:
1. On the opening page, select Event Logger
2. On the second page, select Analyse
The error log is analysed and all errors with a severity level that calls for service
intervention are displayed.

The SRN Table

The table in this section lists the SRNs and describes the actions you should take. The
table columns are:
Abbreviations used in the table are:
SRN The service reference number.
FRU list The FRU or FRUs that might be causing the problem, and how likely it is
(by percentage) that the FRU is causing the problem.
Problem A description of the problem and the action you must take.
DMA Direct memory access
FRU Field-replaceable unit
PAA P = Adapter port number
AA = SSA address
(see also “Finding the Device When No Service Aids Are Available” on
page 38)
PCI Peripheral Component Interconnect
POST Power-On Self-Test

Using the SRN Table

Important: You should have been sent here from either diagnostics or a START MAP.
Do not start problem determination from the SRN table; always go to the START MAP
for the unit in which the device is installed.
