Service request numbers (SRNs) serve as diagnostic aids
to help users determine the source of a hardware problem. Diagnostic
applications report problems by using SRNs. The SRN identifies the
component that detected the error code and describes the error condition.
Use this information to identify a list of possible failing items
and to find information about any additional isolation procedures.
If your System reference code (SRC) is a five-digit hexadecimal
number or contains a hyphen in the following formats (xxxxx, xxx-xxx,
xxx-xxxx, xxxx-xxx, xxxx-xxxx), it is an SRN.
How to use the service request numbers
The list of SRNs
is in numeric order. The SRNs in each range can include codes that
consist of 6 to 8 digits. When the SRN you are looking for contains
3 digits before the dash, select the link that contains the first
3 digits followed by the dash of that SRN. Use the same process when
the SRN you are looking for contains 4 digits before the dash.
The SRN tables use the following format:
- The first column, Service Request Number (SRN), contains numbers
that represent specific failures of specific functions.
- The second column, SRN SRC. (SRN source code), contains the code
that identifies the program or procedure that produced the SRN. For
more information about using SRN SRC codes, see SRN source code.
- SRNs contain Failing Function Codes (FFCs). The FFC represents
field replaceable units (FRUs) of the system unit. When available,
the FFC links to the FRU that contains this function for each specific
system unit.
- The SRN also contains an action or servicer response. Typically
it is brief description of the failure that this SRN represents and
an isolation procedure that should be used when servicing the system.
Do the following when you attempt to locate your specific
SRN information:
- Use the online reference code finder. Go to Reference code finder.
- Record the failing function codes in the order listed. Service
or replace the possible failing FRU in the order listed.
- Perform the isolation procedures that are listed in the servicer
response area of the SRN.
Note: If your SRN is not listed, check to
see whether xxx or xxxx has been used. The -xxx or -xxxx should
always be the last SRN identified within a specific prefix. For example,
for SRN 950-xxxx, the xxxx represents the last entry within the 950
prefix.
SRN source code
When
using SRNs to identify a problem and its resolution, you might need
to refer to the source code of the SRN. The SRN source code identifies
the program or procedure that produced the SRN. SRN source codes include
the following:
| SRN source code |
Description |
| A |
The SRN is from a steady number in the control (operator)
panel display |
| B |
The SRN is from a MAP (problem isolation procedure) callout. |
| C |
The SRN was due to a missing resource at configuration time. |
| D |
The SRN is from a diagnostic test after complete isolation
testing. |
| E |
The SRN is from a POST failure. |
| F |
The SRN is from a diagnostic test after partial isolation
testing. |

- The asterisk (*) is an accepted wildcard.
- SRCs are strings of either 6 or 8 alphanumeric characters in the
formats ΧΧΧΧΧΧ or ΧΧΧΧΧΧΧΧ.
Examples: 110000AD, C6003900, B7*988
- Progress codes are strings of 8 characters that begin with a C
(except CB) or D (except DA). Examples: C1001F0D, D101C00F, D11A1xxx,
D11A1*, D1*B0FF
- HMC error codes and messages are strings of 8 characters that
begin with an H or strings of 6 characters that begin with a zero
(0), and they do not include a hyphen. Examples: HSCL0003,
HSCP0021, HSCI0104, 0x0007, 0*0104
- AIX diagnostic messages are strings of 3 or 4 characters. Examples: 887,
2621, c33, c54, 0c0, 700, 558
- SRNs are either strings of five hexadecimal numbers or numeric
strings in the following formats xxxxx, xxx-xxx, xxx-xxxx, xxxx-xxx,
xxxx-xxxx. Examples: 301C0, 733-120, 2502-3010
- Symbolic FRUs are procedures that are used to diagnose problems
with features and parts. Examples: ACMODUL, AIRMOVR, CAPACTY, LPARCFG,
FWNIM, PWRSPLY, UC235
- Failing function codes represent functions within the system unit.
Examples: 11A, 201, 2E01, E30, B71
- Failing item codes indicate which is the failing item. Examples: FI00021,
FI00090, FI00718, FI01140
- Isolation procedures are used together with diagnostic programs
to isolate problem. Examples: RIOIP11, MABIP51, COMPIP1, PWR1905,
