Chapter 6 Diagnostics, Monitoring, and Troubleshooting 167
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-level setting 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.
