System-Event Log; Integrated Management Module Error Messages - IBM 7378 Problem Determination And Service Manual

System-event log

The system-event log contains messages of three types:
Information
Warning
Error
Each message contains date and time information, and it indicates the source of
the message (POST or the IMM).

Integrated management module error messages

The following table describes the IMM error messages and suggested actions to
correct the detected problems. For more information about IMM, see the Integrated
Management Module User's Guide at http://www.ibm.com/systems/support/
supportsite.wss/docdisplay?lndocid=MIGR-5079770&brandind=5000008.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 4, "Parts listing, System x3400 M3 Types 7378 and 7379," on page 141 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.

Information messages do not require action; they record significant
system-level events, such as when the server is started.
Warning messages do not require immediate action; they indicate possible
problems, such as when the recommended maximum ambient temperature
is exceeded.
Error messages might require action; they indicate system errors, such as
when a fan is not detected.
Severity Description

going high has asserted.

Error A lower critical sensor going
low has asserted.
Error An upper critical sensor
going high has asserted.
Error A lower critical sensor going
low has asserted.
Error An upper critical sensor
going high has asserted.
Error A lower critical sensor going
low has asserted.
