System Console OpenBoot
Configuration Variable Settings
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 port and network management port.
Note – 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 1-3, there are
other variables that affect and determine system behavior. These variables are
discussed in more detail in Appendix A.
