How to Set the Diagnostic Level for
POST and OBDiag
Before You Begin
Three different levels of diagnostic testing are available for power-on self-test
(POST) and OpenBoot Diagnostics (OBDiag): max (maximum level), min (minimum
level), and off (no testing). The system runs the appropriate level of diagnostics
based on the setting of the OpenBoot PROM (OBP) variable called diag-level.
The default setting for diag-level is min.
If your server is set up without a local console or terminal, you’ll need to set up a
monitor, console, or terminal before setting the diagnostic level. See “About
Communicating With the Server” on page 28.
