Configuration Procedure for a 2-Node EPC with 1 System Console
The procedure is performed from the ASCII terminal connected to S1 plug of node#1 and
allows to switch from node #1 system console to node #2 system console, when a
multi–port async board is present and the two nodes are linked with a serial cable as
depicted in the previous figure.
Configuration
1. Log in as root user.
2. Create the ttyx device using smit tty menus relative to the link established between the
8–port board and the S1 plug of node #2.
3. Setup this device with the following characteristics:
baud rate = 9600
bits = 8
bit stop = 1
parity = non
DTR = ignored
Duplex = Full
Echo = OFF
4. Update the file /etc/uucp/Devices by adding the following line after the commented lines
as below:
Direct ttyx –9600 direct
where ttyx is the device created with smit in the above step.
Connection
There are two possibilities to connect as a system console to node #2:
cu –l ttyx
pwcons –c ttyx
The pwcons utility comes with the Bull Cluster software package. This is a shell script build
above the cu command which is installed in the /usr/sbin directory.
For more details, refer to the EPC & HA Solutions – Setup Guide.
At this point the AIX login banner of node #2 is displayed on the screen and it is possible to
log in as usual.
Disconnection
Logout from node #2.
Close the connection by keying (Tilde and period):
~.
