Chapter 1 Configuring the System Console 3
What the System Console Does
The system console displays status and error messages generated by firmware-based
tests during system startup. After running those tests, you can enter special
commands that affect the firmware and alter system behavior. For information about
the tests that run during the boot process, refer to the service manual for your server.
Once the operating system is booted, the system console displays UNIX system
messages and accepts UNIX commands. You can access the system console using the
ALOM CMT
console
command.
What the System Controller Console Does
The system controller console displays the results of the ALOM CMT boot
diagnostics and initialization.
If it receives no user input within 60 seconds, ALOM CMT automatically connects to
the system console. To return to the system controller, type the console escape
sequence
#.
(Hash-Period).
Using the System Console
To use the system console, you need to attach an I/O device to the system. Initially,
you might have to configure that hardware, and load and configure appropriate
software as well.
