B.4.3 Example of the Single system in Takeover physical IP address (pattern II)

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    hosta   # HOST-A Virtual IP
192.168.70.3    hostb   # HOST-B Virtual IP
192.168.70.100  swhub1  # Primary HUB IP
192.168.70.101  swhub2  # Secondary HUB 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
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 and reboot the system. After rebooting the system, verify eth0 is enabled using ifconfig command.

/sbin/shutdown -r now

3) Setting a subnet mask

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0

4) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m e -i 192.168.70.1 -t eth0,eth1

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101 -b off

6) Setting up the Standby patrol monitoring function

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -t sha0

7) Activating of virtual interface

/opt/FJSVhanet/usr/sbin/strhanet -n sha0

8) Starting the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll on

[HOST-B]
