After you have configured the network, network initialization will fail. To correct
this problem, update the Intel e1000 drivers and update SLES 7 or 8 to the latest
level kernel available.

Update the configuration files

Now that the Management Node can communicate with other devices in the
cluster take the following steps:
1. Update /etc/modules.conf with the following lines:
alias eth0 e1000
alias eth1 e1000
alias eth2 e1000
2. Edit or create the /etc/rc.config file and make sure it contains the following
directives:
#
# IP Addresses
#
IPADDR_0="172.20.0.1"
IPADDR_1="172.30.0.1"
IPADDR_2=""
IPADDR_3="
#
# Network device names (e.g. "eth0")
#
NETDEV_0="eth0"
NETDEV_1="eth1"
NETDEV_2=""
NETDEV_3=""
#
# Parameters for ifconfig, simply enter "bootp" or "dhcpclient" to use
# the respective service for configuration. Sample entry for ethernet:
# IFCONFIG_0="192.168.81.38 broadcast 192.168.81.63 netmask 255.255.255.224"
#
IFCONFIG_0="172.20.0.1 broadcast 172.20.255.255 netmask 255.255.0.0"
IFCONFIG_1="172.30.0.1 broadcast 172.30.255.255 netmask 255.255.0.0"
