Oracle Diagnostic Tools

Oracle provides a wide selection of diagnostic tools for use with your server. These
tools range from the SunVTS™ software, a comprehensive validation test suite, to log
files in ILOM that might contain clues helpful in identifying the possible sources of a
problem, and the fault management function in ILOM that enables you to identify a
faulted component as soon as the fault occurs.
The diagnostic tools range from standalone software packages, to firmware-based
tests like power-on self-test (POST), U-Boot tests, or Pc-Check tests, to hardware
LEDs that tell you when the system components are operating.
