You can issue system commands and view system messages using your local
graphics monitor. If you want to redirect the system console back to the serial
management and network management ports, see
“Using the OpenBoot
Configuration Variables” on page 15 .
Using the OpenBoot Configuration Variables
The system console is directed to the serial management and network management
ports (SER MGT and NET MGT). If you have connected a graphics monitor the
output is directed to that device by default. You can also redirect the system console
back to the serial management and network management ports.
Certain OpenBoot configuration variables control from where system console input
is taken and to where its output is directed. The following table shows how to set
these variables in order to use the serial management and network management
ports, or a local graphics monitor as the system console connection.
* POST output is still directed to the serial management port, as POST has no mechanism to direct its output to a
graphics monitor.
The serial management port does not function as a standard serial connection. If you
want to connect a conventional serial device (such as a printer) to the system, you
must connect it to TTYA not the serial management port.
It is important to note that the
sc>
prompt and POST messages are only available
through the serial management port and network management port. In addition, the
ALOM
console
command is ineffective when the system console is redirected to a
local graphics monitor.
