Chapter 1 Configuring the System Console 23
System Console OpenBoot
Configuration Variable Settings
The server’s system console is directed to the serial management and network
management ports (SER MGT and NET MGT) by default.
Certain OpenBoot configuration variables control from where system console input
is taken and to where its output is directed. The table below shows how to set these
variables in order to use the serial management and network management ports.
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 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.
