The construction of serial port driver for the duplicated console path is automatically carried out according to OBP environment variable "tty-conspath" and "tty-sub-conspath."
If the environment variables of OBP (OpenBootPROM),"tty-conspath" and "tty-sub-conspath", are not set, two serial ports on the system board installed in the smallest slot number are automatically selected for the console from among the system boards which comprise the partition.
You can select the serial port for the console by setting the environment variable of OBP.
Even if the composition of the system board in a partition was changed, these environment variables do not change. Therefore, when partition composition is changed, you must reconfirm these variables, and they need to be set as the system board which surely exists in the partition.
If the system boards defined as "tty-conspath" and "tty-sub-conspath" do not exist in the partition, the serial port of the system board on which the smallest number in a partition was attached will turn into a serial port for consoles. However, the value of "tty-conspath" and "tty-sub-conspath" are not changed.
Please also refer to the following documents about a setup about console connection.
