Service Processor Problems - IBM PS703 Service Manual

Service processor problems

The baseboard management controller (BMC) is a flexible service processor that provides error
diagnostics with associated error codes, and fault isolation procedures for troubleshooting.
Note: Resetting the service processor causes a POWER7 reset/reload, which generates a dump. The
dump is recorded in the management module event log. The reset/reload dump occurs whenever the
service processor resets, such as when resetting the service processor through the management module
Web interface or through the management module command line interface.
When the advanced POWER7 service processor error analysis determines a specific fault, the service
processor logs an error code to identify the failing component. When the analysis is not definitive, the
service processor logs one or more isolation procedures for you to run to identify and correct the
problem.
The service processor reports fault isolation procedure codes to identify a specific service action. The
isolation procedure code is recorded in the management-module event log.
A message with three procedures might be similar to the following example, except that the entry would
be on one line in the event log:
(SN#YL31W7120029) SYS F/W: CEC Hardware VPD.
See procedure FSPSP07, FSPSP28 then FSP0200
(5000004C B15A3303 22222222 33333333 44444444 55555555
66666666 77777777 88888888 99999999)
B15A3303 is the identifier word of the associated SRC. The rest of the nine words in the SRC are shown in
sequence.
A message that identifies customer replaceable units (CRUs) might be similar to the following example:
(SN#YL31W7120029) SYS F/W: Error. Replace PIOCARD then Sys Brd
(500213A0 B7006973 22222222 33333333 44444444 55555555
66666666 77777777 88888888 99999999)
A message with multiple replacement callouts might be too long to display. In such a case, the message
removes SRC words starting with word 2 and inserts an X for every removed word. The following
example shows an error log entry that did not have enough room for words 2 and 3:
(SN#YL31W7120029) SYS F/W: CEC Hardware VPD.
See procedure FSPSP07, FSPSP28 then FSP0200
(50000014 B15A3303 XX 44444444 55555555 66666666
77777777 888888888 99999999)
