10. Use ALOM to run POST diagnostics.
Doing this involves several steps.
a. Type:
sc> bootmode diag
This command temporarily overrides the server's OpenBoot Diagnostics diag-
switch? setting, forcing power-on self-test (POST) diagnostics to run when
power is cycled off and on. If the server is not power cycled within 10 minutes, it
reverts back to its defaults.
b. Power cycle the system. Type:
sc> poweroff
Are you sure you want to power off the system [y/n]? y
sc> poweron
POST diagnostics begin to run as the system reboots. However, you will see no
messages until you switch from ALOM to the system console. For details, see
"About Switching Between the ALOM System Controller and the System
Console" on page 175.
