B.8.2 Example of the Cluster system (1:1 Standby)

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".
For configuring the cluster system, refer to the Cluster system manual.
In this section, description of private LAN is omitted.
The dotted line indicates that the interface is inactive.

Note

When specifying an IPv6 address for the target IP of HUB monitoring, specify the link local address of the neighboring switch.
If an address other than the link local address is specified, the following event may occur:
- When a cluster application is switched, an error is detected temporarily by HUB monitoring.

[HOST-A]

1) Setting up the system

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

fc00:80::1    v6hosta    # HOST-A Virtual IP
fc00:80::2    v6hostb    # HOST-B Virtual IP
fc00:80::3    v6host1    # HOST-A/B (Takeover virtual IP)
fe80::xx:1    swhub1     # Primary HUB IP
fe80::xx:2    swhub2     # Secondary HUB IP

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

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

DEVICE=eth0
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
DEVICETYPE=hanet

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

DEVICE=eth1
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
DEVICETYPE=hanet

1-3) On the /etc/sysconfig/network file, define a statement that allows the system to load IPv6 module.

NETWORKING=yes
NETWORKING_IPV6=yes
IPV6TO4INIT=no

2) Creating a virtual interface

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

3) Setting an IP address

Define an IP address or other entries in /etc/sysconfig/network-scripts/ifcfg-sha0 file.

Contents of /etc/sysconfig/network-scripts/ifcfg-sha0

DEVICE=sha0
IPV6INIT=yes
IPV6ADDR=fc00:80::1/64
BOOTPROTO=static
ONBOOT=yes
DEVICETYPE=sha
HOTPLUG=no

4) Setting the network monitoring function

/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p fe80::xx:1,fe80::xx:2

5) Creating a takeover virtual interface

/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0 -i fc00:80::3/64

6) Reboot

Run the following command to 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) Edit the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file. Defined content is same as HOST-A other than the value of HWADDR.

1-3) Define a statement to enable the network configuration in /etc/sysconfig/network file. Defined content is same as HOST-A.
