PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.2 (for Linux)

B.1.2 Example of the Single system in Logical virtual interface

This section describes an example configuration procedure of the network shown in the diagram below.

For the network configuration other than GLS, refer to "3.2.2 Network configuration".

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file.

192.168.70.1    host11  # HOST-A Physical IP
192.168.71.1    host12  # HOST-A Physical IP
192.168.80.1    hosta   # HOST-A Virtual IP
192.168.80.3    hosta1  # HOST-A Logical virtual IP 
192.168.70.2    host21  # HOST-B Physical IP
192.168.71.2    host22  # HOST-B Physical IP
192.168.80.2    hostb   # HOST-B Virtual IP

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

In example (/etc/sysconfig/network-scripts/ifcfg-ethX) of setting the following, operating system is an example of RHEL4. Please refer to "3.2.2 Network configuration" for the setting examples other than RHEL4.

- Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
BROADCAST=192.168.70.255
IPADDR=192.168.70.1
NETMASK=255.255.255.0
NETWORK=192.168.70.0
ONBOOT=yes
TYPE=Ethernet

- Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
BROADCAST=192.168.71.255
IPADDR=192.168.71.1
NETMASK=255.255.255.0
NETWORK=192.168.71.0
ONBOOT=yes
TYPE=Ethernet

1-3) When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

NETWORKING=yes
NETWORKING_IPV6=no

2) Reboot

Run the following command to reboot the system. After rebooting the system, verify eth0 and eth1 are active using ifconfig command.

/sbin/shutdown -r now

3) Setting a subnet mask

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0

4) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m t -i 192.168.80.1 -t eth0,eth1

5) Creating of logical virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0:2 -i 192.168.80.3

6) Activating of virtual interface and logical virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

[HOST-B]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file. Defined content is same as HOST-A.

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

In example (/etc/sysconfig/network-scripts/ifcfg-ethX) of setting the following, operating system is an example of RHEL4. Please refer to "3.2.2 Network configuration" for the setting examples other than RHEL4.

- Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
BROADCAST=192.168.70.255
IPADDR=192.168.70.2
NETMASK=255.255.255.0
NETWORK=192.168.70.0
ONBOOT=yes
TYPE=Ethernet

- Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
BROADCAST=192.168.71.255
IPADDR=192.168.71.2
NETMASK=255.255.255.0
NETWORK=192.168.71.0
ONBOOT=yes
TYPE=Ethernet

1-3) When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

NETWORKING=yes
NETWORKING_IPV6=no

2) Reboot

Run the following command to reboot the system. After rebooting the system, verify eth0 and eth1 are active using ifconfig command.

/sbin/shutdown -r now
