How To Set The Diagnostic Level For Post And Obdiag - Sun Microsystems Enterprise 250 Owner's Manual

How to Set the Diagnostic Level for
POST and OBDiag
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" on
page 49.
