Creating the TTY device within AIX

 < Day Day Up > 

The creation of a tty device on each node is required for the serial heartbeat. This is done through the SMIT interface (it must be run by root). At this point, you can connect your serial cable (null modem Cable).


If you connect your cable before you define your device, your graphical display may not work because the boot process will see a device connected to the serial port and assume it is a terminal.

Use the following link to Create the TTY Device within AIX:

SMIT -> Devices -> TTY -> Add a TTY -> tty rs232 Asynchronous Terminal -> sa0 Available 00-00-S1 Standard I/O Serial Port1
