How to View and Set OpenBoot Configuration Variables

Switches and diagnostic configuration variables stored by the system firmware determine how and when power-on self-test (POST) diagnostics and OpenBoot Diagnostics tests are performed. This section explains how to access and modify OpenBoot configuration variables. For a list of important OpenBoot configuration variables, see TABLE 6-2.

Before You Begin

Halt the server to reach the ok prompt. See:

■“About the ok Prompt” on page 49

What to Do

●To display the current values of all OpenBoot configuration variables, use the printenv command.

The following example shows a short excerpt of this command’s output.

ok printenv
