25 Debugging and Diagnostics This chapter contains three sections: • Offline Diagnostic Commands • Hardware Commands Offline Diagnostic Commands The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, the Dell Force10 operating software (FTOS) results are saved as a text file (TestReport-SU-X.txt) in the flash directory. The show file command is available only on Master and Standby. Important Points to Remember • Offline diagnostics can only be run when the unit is offline. • Offline diagnostics cannot be run in Stacking mode. • You can only run offline diagnostics on a unit to which you are connected via the console. In other words, you cannot run diagnostics on a unit to which you are connected via a stacking link. • Diagnostic results are stored in a file (TestReport-SU-X.txt) in the flash directory. To review the results, use the show file command, which prints the results to the screen. • Diagnostics only test connectivity, not the entire data path. The offline diagnostics commands are: • diag stack-unit • offline stack-unit • online stack-unit • show diag Hardware Commands These commands display information from a hardware sub-component or ASIC. The hardware commands are: • clear hardware stack-unit • hardware watchdog • show diag Debugging and Diagnostics | 245
