7.7 How to Set the Diagnostic Level for POST and OBDiag

7.7.1 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 variable diag-level.

The default setting for diag-level is min.

If your server is set up without a local console or terminal, you will need to set up a monitor, console, or terminal before setting the diagnostic level. See "2.10 About Communicating With the Server".

7.7.2 What to Do

Perform this procedure with the power on and the keyswitch set to the Power-On/Off position.

1. With the keyswitch in the Power-On/Off position, press the Break key on your alphanumeric terminal's keyboard, or enter the Stop-a sequence on a Sun keyboard.

   To enter the Stop-a sequence, press the Stop key and the a key simultaneously. The ok prompt is displayed.

2. To set the diag-level variable, type the following:

   ok setenv diag-level value

The value can be off, min, or max. See "7.5.2 Configuration Variable" for information about each setting.
