Chapter 3. Operating system configuration

This section provides instructions for configuring your operating system for SOL

operation, including any required installation of device drivers. It includes the

following instructions:

v

“Linux configuration”

–

“Red Hat Enterprise Linux ES 2.1 configuration”

–

“SUSE SLES 8.0 configuration” on page 19

–

“Installing the Ethernet controller device driver for Linux operating systems”

on page 21

v

“Microsoft Windows 2003 Standard Edition configuration” on page 22

Linux configuration

Complete one of the following procedures to enable SOL sessions for your Linux

operating system. You must be logged in as a root user to perform these

procedures. For SOL operation, you must also configure the Linux operating

system to expose the Linux initialization (booting) process. This enables users to

log in to the Linux console using an SOL session and directs Linux output to the

serial console. See the documentation for your specific Linux operating-system type

for information and instructions.

Note:

You do not have to configure the Linux operating system when using a

BladeCenter JS20 Type 8842 blade server; however, you still must install the

Ethernet controller device drivers (see “Installing the Ethernet controller device

driver for Linux operating systems” on page 21).

Red Hat Enterprise Linux ES 2.1 configuration

Note:

This procedure is based on a default installation of Red Hat Enterprise

Linux ES 2.1. The file names, structures, and commands might be different for

other versions of Red Hat Linux.

Complete the following steps to configure the general Linux parameters for SOL

operation when using the Red Hat Enterprise Linux ES 2.1 operating system.

Note:

Hardware flow control prevents character loss during communication over a

serial connection. You must enable it when using a Linux operating system.

1.

Add the following line to the end of the

# Run gettys in standard runlevels

section of the /etc/inittab file. This enables hardware flow control and enables

users to log in through the SOL console.

7:2345:respawn:/sbin/agetty -h ttyS1 19200 vt102

2.

Add the following line at the bottom of the /etc/securetty file to enable a user

to log in as the root user through the SOL console:

ttyS1
