Chapter 1 Configuring the System Console 29
System Console OpenBoot
Configuration Variable Settings
On the SPARC Enterprise T5140 and T5240 servers, the system console is directed to
the serial management and network management ports (SER MGT and NET MGT)
by default. However, you can redirect the system console to a local graphics monitor,
keyboard, and mouse. You can also redirect the system console back to the serial
management and network management ports.
Certain OpenBoot configuration variables control where system console input is
taken from and where its output is directed. The following table shows how to set
these variables in order to use either the serial management and network
management ports, or a local graphics monitor as the system console connection.
Note – POST output will still be 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 to the serial management port.
The -> prompt and POST messages are only available through the serial
management port and network management port. The ILOM service processor
start /SP/console
command is ineffective when the system console is redirected
to a local graphics monitor.
In addition to the OpenBoot configuration variables described in TABLE 1-4 , there are
other variables that affect and determine system behavior. These variables are
discussed in more detail in
Appendix A .
