Before You Begin

Four different levels of diagnostic testing are available for power-on self-test (POST) and OpenBoot Diagnostics (OBDiag): max (maximum level), med (medium level), min (minimum level), and off (no testing). The system runs the appropriate level of diagnostics based on the setting of the OpenBoot PROM variable called diag-level.

The default setting for diag-level is min.

If your server is set up without a local console, you'll need to set up a monitor or console before setting the diagnostic level. See "About Setting Up a Console".
