How To Bypass Firmware Diagnostics - Sun Microsystems Sun Fire V440 Diagnostics And Troubleshooting Manual

3. Set OpenBoot configuration variables to trigger diagnostic tests. Type:
ok setenv post-trigger power-on-reset error-reset
ok setenv obdiag-trigger power-on-reset error-reset
4. Set the maximum POST diagnostic test level. Type:
ok setenv diag-level max
This ensures the most thorough power-on self-test possible. The maximum testing
level requires considerably longer to complete than the minimum. Depending on
system configuration, you may need to wait an additional 10 to 20 minutes for the
server to boot.

How to Bypass Firmware Diagnostics

POST and OpenBoot Diagnostics tests can be bypassed to expedite the server's
startup process. For background information, see:
"Diagnostics: Reliability versus Availability" on page 14
Caution – Bypassing diagnostic tests sacrifices system reliability by allowing a
system to attempt to boot when it may have a serious hardware problem.
Before You Begin
Log in to the system console and access the ok prompt. For instructions, see:
"How to Get to the ok Prompt" on page 176
What to Do
1. Make sure that the server's system control keyswitch is set to the Normal position.
Setting the keyswitch to the Diagnostics position overrides the OpenBoot
configuration variable settings and causes diagnostic tests to run.
