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.
