Service Processor Problems - IBM BladeCenter JS22 Problem Determination And 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 POWER6 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 POWER6 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)
