B.6.1 Example of the Single system without NIC sharing

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

The xx in the figure below are assigned automatically by the automatic address configuration.

For the network configuration other than GLS, refer to "3.2.2 Network configuration".
The dotted line indicates that the interface is inactive.

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file. Note that it is not necessary to define an IPv6 address, which automatically allocates address by the Stateless Address Autoconfiguration feature.

192.168.70.1    hosta   # HOST-A Virtual IP
192.168.70.2    host11  # HOST-A Physical IP
192.168.70.3    hostb   # HOST-B Virtual IP
192.168.70.4    host21  # HOST-B Physical IP
192.168.70.100  swhub1  # Primary HUB IP
192.168.70.101  swhub2  # Secondary HUB IP
fec0:1::1       v6hosta    # HOST-A Virtual IP
fec0:1::2       v6hostb    # HOST-B Virtual IP

1-2) Describe the IP address defined in the above in the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file.

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

DEVICE=eth0
BOOTPROTO=static
HOTPLUG=no
IPADDR=192.168.70.2
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet

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

DEVICE=eth1
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

2) Reflecting system setting

Run the following command and reboot the system. After rebooting the system, verify eth0 is enabled as an IPv4/IPv6 interface using the ip 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) Creation of IPv4 virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.1 -e 192.168.70.2 -t eth0,eth1

Note

Ensure that the physical IP address specified using option '-e' is the same IP address configured in /etc/sysconfig/network-scripts/ifcfg-eth0.

5) Creation of IPv6 virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig copy inet6 -n sha0,sha0 -i fec0:1::1/64

6) 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

7) Setting up the Standby patrol monitoring function

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

8) Activating the virtual interface

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

9) Starting the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll on
