Uefi/Post; Ibm Dynamic System Analysis - IBM 7383 Installation And Service Manual

UEFI/POST

When you turn on the server, it performs a series of tests to check the operation of
the server components and some optional devices in the server. This series of tests
is called the power-on self-test, or POST.
Note: This server does not use beep codes for server status.
If a power-on password is set, you must type the password and press Enter (when
you are prompted), for POST to run.
If POST detects a problem, an error message is displayed. See Appendix A,
"UEFI/POST error codes," on page 343 for more information.
If POST detects a problem, an error message is sent to the POST event log, see
"Event logs" on page 144 for more information.

IBM Dynamic System Analysis

IBM Dynamic System Analysis (DSA) collects and analyzes system information to
aid in diagnosing server problems.
DSA collects the following information about the server:
v Drive health information
v Event logs for ServeRAID controllers and service processors
v Hardware inventory, including PCI and USB information
v Installed applications and hot fixes (available in DSA Portable only)
v Kernel modules (available in DSA Portable only)
v Light path diagnostics status
v Network interfaces and settings
v Performance data and details about processes that are running
v RAID controller configuration
v Service processor (integrated management module) status and configuration
v System configuration
v Vital product data and firmware information
For system-specific information about the action that you should take as a result of
a message that DSA generates, see Appendix B, "DSA messages," on page 361.
If you cannot find a problem by using DSA, see "Solving undetermined problems"
on page 168 for information about testing the server.
Note: DSA Preboot might appear to be unresponsive when you start the program.
This is normal operation while the program loads.
Make sure that the server has the latest version of the DSA code. To obtain DSA
code and the Dynamic System Analysis Installation and User's Guide, go to
