Diagnostic Tools
The selection of diagnostic tools available for your server range in complexity from
a comprehensive validation test suite (Oracle VTS) to a chronological event log (Oracle
ILOM System Log). The selection of diagnostic tools also includes standalone software
packages, firmware-based tests, and hardware-based LED indicators.
The following table summarizes the diagnostic tools that you can use when
troubleshooting or monitoring your server.
|
|
|
|
|
|
Oracle ILOM
|
SP firmware
|
Monitors environmental condition and component functionality sensors,
generates alerts, performs fault isolation, and provides remote access.
|
Can function on either standby power mode or full power mode and is
not OS dependent.
|
Designed for remote and local access.
|
|
Preboot Menu
|
SP firmware
|
Enables you to restore some Oracle ILOM default settings when Oracle
ILOM is not accessible.
|
Can function on standby power and when operating system is not
running.
|
Local, but remote serial access is possible if the SP serial port is
connected to a network-accessible terminal server.
|
|
Hardware-based LED indicators
|
Hardware and SP firmware
|
Indicates status of overall system and particular components.
|
Available when system power is available.
|
Local, but sensor and indicators are accessible from Oracle ILOM web
interface or command-line interface (CLI).
|
|
Power-On Self-Test (POST)
|
Host firmware
|
Tests core components of system: CPUs, memory, and motherboard I/O
bridge integrated circuits.
|
Runs on startup. Available when the operating system is not running.
|
Local, but can be accessed through Oracle ILOM Remote System Console
Plus.
|
|
U-Boot
|
SP firmware
|
Initializes and test aspects of the service processor (SP) prior to
booting the Oracle ILOM SP and operating system. Tests SP memory, SP,
network devices and I/O devices.
|
Can function on standby power and when operating system is not
running.
|
Local, but remote serial access is possible if the SP serial port is
connected to a network-accessible terminal server.
|
|
UEFI Diagnostics
|
SP firmware
|
The UEFI diagnostics can test and detect problems on all processors,
memory, disk drives, and network ports.
|
You can use either the Oracle ILOM web interface or the command-line
interface (CLI) to run UEFI diagnostics.
|
Remote access through Oracle ILOM Remote System Console Plus.
|
|
Oracle Linux commands
|
Operating system software
|
Displays various kinds of system information.
|
Requires operating system.
|
Local, and over network.
