About Startup Diagnostics

Startup diagnostics are hardware tests that are embedded in the Sun Blade 8000 Series firmware; they are run automatically when the system, or individual components, are powered on or reset. Startup diagnostics test the hardware on the following system components:

Diagnostics run at power-on and, usually, when the component is reset. These tests specifically target CPUs and memory, local I/O and I/O fabric, and the chassis environment.

All startup diagnostics have the same goals: stimulate the component, observe the resultant behavior, and determine whether the behavior is expected. If the behavior is not expected (if a test fails), prevent the component from starting and, if possible, notify the fault management software (running on the CMM) of the error.
