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 event 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.
Diagnostic Tool | Type | What It Does | Accessibility | Remote Capability |
---|---|---|---|---|
Oracle ILOM |
SP firmware |
Monitors environmental condition and component functionality sensors, generates alerts, performs fault isolation, and provides remote access. |
Can function in either Standby power mode or Main power mode and is not OS dependent. |
Remote and local access. |
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. |
UEFI Diagnostics |
SP firmware |
Tests and detects problems on all processors, memory, disk drives, and network ports. |
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 ILOM SP/Diag shell |
SP firmware |
Allows you to run HWdiag commands to check the status of a system and its components, and access HWdiag logs. |
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. |
Oracle Solaris commands |
Operating system software |
Displays various kinds of system information. |
Requires operating system. |
Local, and over network. |
Oracle Linux commands |
Operating system software |
Displays various kinds of system information. |
Requires operating system. |
Local, and over network. |
Oracle VTS |
Diagnostic tool standalone software |
Exercises and stresses the system, running tests in parallel. |
Requires the Oracle Solaris operating system. Install Oracle VTS software separately. |
View and control over network. |
