Appendix F. SSA Software and Microcode Errors

This appendix provides an explanation of serial storage architecture (SSA) software,
service request numbers (SRNs), and microcode errors.

Service Request Numbers (SRNs)

Service request numbers (SRNs) are generated for the SSA hot-swap disk drive by the
system error-log analysis, system configuration code, diagnostics, and customer
problem-determination procedures. 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.
If you get an SRN that is not defined in the following table, see Advanced SerialRAID
Adapters User's Guide and Maintenance Information, order number SA33-3285.
SSA documentation is available online. To access the online books, visit the following

SRN Table

Table 12 on page 429 lists the SRNs and describes the actions you should perform.
The table columns are as follows:
SRN
FRU List
%
Problem

Using the SRN Table

Important: You should have been sent here from SSA Maintenance Analysis
Service reference number
FRU or FRUs that might be causing the problem (see also "FRU
Names and Abbreviations Used in the SRN Table" on page 428)
Probability (by percentage) that the FRU is causing the problem
Description of the problem and the action you must take
Procedures (MAPs) or RS/6000 and Eserver pSeries Diagnostic
Information for Multiple Bus Systems, order number SA38-0509. Do not
start problem determination from the SRN table; always go to "SSA
Maintenance Analysis Procedures (MAPs)" on page 75 first.
1. Locate the SRN in the table. If you cannot find the SRN, there is a
problem with the diagnostics, the microcode, or the documentation. Call
your support center for assistance.
2. Read carefully the "Action" you must perform for the problem. Do not
exchange FRUs unless you are instructed to do so.
3. Normally exchange only one FRU at a time, starting from the top of the
FRU list for that SRN. Always use instructions given in the page
reference when exchanging FRUs. After each FRU is exchanged, go to
"MAP 410: Repair Checkout" in RS/6000 and Eserver pSeries
Diagnostic Information for Multiple Bus Systems to verify the repair.
