About Diagnostic Levels

Four different levels of diagnostic testing are available for power-on self-test (POST) and OpenBoot Diagnostics control. The level of testing performed is based on the setting of the OpenBoot PROM configuration variable diag-level, as follows:

off — Either no testing or initialization only

min — Fast, minimum level of testing (the default setting)

max — Extensive and time-consuming testing

menus — POST runs to completion, and then brings up the following POST menu, which you can use to run individual power-on self-tests

For instructions on how to set the level of diagnostic testing, see “How to Set the Diagnostics Level” on page 186. Note that if the diag-levelsetting is menus, OpenBoot Diagnostics uses the setting min or max, depending on the test performed.

You can also use RSC to temporarily set the boot mode for a reboot that occurs within 10 minutes. Using RSC to set the boot mode is similar to using L1-N key combinations on non-USB Sun keyboards (the Sun Fire 280R server uses a USB keyboard). See the Sun Remote System Control (RSC) User’s Guide for information about the bootmode and rscadm bootmode commands.
