Bios-Logged Bmc System-Event Log Messages; Solving Scsi Problems - IBM System x3755 Problem Determination And Service Manual

BIOS-logged BMC system-event log messages

BIOS can log two types of system-event log messages: POST events, which occur
during system startup, and SMI events, which are generally run time errors detected
by hardware.
The server logs OEM-specific BIOS messages in the BMC system-event log. The
following table describes the four BIOS record types logged in the BMC
system-event log. You can obtain third-party software to provide BMC system-event
log translations for detailed byte definitions and repair actions.
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 3, "Parts listing, System x3755 Type 8877 and 7163," on page 25 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.

Solving SCSI problems

Note: This information also applies to Serial Attached SCSI (SAS) problems.
For any SCSI error message, one or more of the following devices might be
causing the problem:
v A failing SCSI device (adapter, drive, or controller)
v An incorrect SCSI termination jumper setting
