B.6.3 Configuring virtual interfaces with tagged VLAN (Logical IP takeover, Synchronous switching)

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

The xx and yy 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".

[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    host71   # HOST-A Physical IP (Tagged VLAN interface)
192.168.80.1    hostb    # HOST-A Virtual IP
192.168.80.3    host81   # HOST-A Physical IP (Tagged VLAN interface)
192.168.70.2    hostc    # HOST-B Virtual IP
192.168.70.4    host72   # HOST-B Physical IP (Tagged VLAN interface)
192.168.80.2    hostd    # HOST-B Virtual IP
192.168.80.4    host82   # HOST-B Physical IP (Tagged VLAN interface)
192.168.70.100  swhub1   # Primary Switch/HUB IP
192.168.70.101  swhub2   # Secondary Switch/HUB IP
fec0:1::1       v6hosta1 # HOST-A Virtual IP (1)
fec0:2::1       v6hosta2 # HOST-A Virtual IP (2)
fec0:1::2       v6hostb1 # HOST-B Virtual IP (1)
fec0:2::2       v6hostb2 # HOST-B Virtual IP (2)

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

Note

The following setting example (/etc/sysconfig/network-scripts/ifcfg-ethX) is for RHEL5. For details, see "3.2.2 Network configuration".

1-3) Configure /etc/sysconfig/network-scripts/ifcfg-ethX.Y (X is 0,1. Y is 1,2) file as follows.

1-4) When the system is RHEL, on /etc/sysconfig/network file, define a statement allows the system to load IPv6 module.

NETWORKING=yes
NETWORKING_IPV6=yes
IPV6TO4INIT=no
VLAN=yes

2) Reboot

Run the following command and reboot the system. After rebooting the system, verify eth0.1 and eth0.2 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
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0

4) Creating of IPv4 virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.1 -e 192.168.70.3 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.80.1 -e 192.168.80.3 -t eth0.2,eth1.2

Note

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

5) Creating of IPv6 virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig copy inet6 -n sha0,sha0 -i fec0:1::1/64
/opt/FJSVhanet/usr/sbin/hanetconfig copy inet6 -n sha1,sha1 -i fec0:2::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 HUB monitoring function (Synchronous switching)

/opt/FJSVhanet/usr/sbin/hanetpoll copy -n sha0,sha1

8) Setting up the Standby patrol monitoring function

Please define only one Standby patrol monitoring function.

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha2 -m p -t sha0

9) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now

[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.

Note

The following setting example (/etc/sysconfig/network-scripts/ifcfg-ethX) is for RHEL5. For details, see "3.2.2 Network configuration".

1-3) Configure /etc/sysconfig/network-scripts/ifcfg-ethX.Y (X is 0,1. Y is 1,2) file as follows.

4) Creating of IPv4 virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.2 -e 192.168.70.4 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.80.2 -e 192.168.80.4 -t eth0.2,eth1.2

Note

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