B.2.6 Example of the Cluster system (N:1 Standby)

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

The values for xx, and yy in the IP address of 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".
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.
You need at least a remote host using Fast switching mode other than a node used for configuring a Cluster system. For details on configuring a remote host, refer to "B.2.1 Example of the Single system".

1) Setting up the system

1-1) Define an address for takeover virtual IP and host name 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.

fec0:1::10      v6hosta1   # HOST-A/C Takeover virtual IP
fec0:1::20      v6hostb1   # HOST-B/C Takeover virtual IP

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".

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

DEVICE=eth0
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

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

DEVICE=eth1
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 allows the system to load IPv6 module.

NETWORKING=yes
NETWORKING_IPV6=yes
IPV6TO4INIT=no

2) Reboot

Run the following command to reboot the system. After rebooting the system, verify eth0 and eth1 are enabled as an IPv6 interface using ifconfig command.

/sbin/shutdown -r now

3) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create inet6 -n sha0 -m t -t eth0,eth1

4) Creating of takeover virtual interface

/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0 -i fec0:1::10/64

5) Setting up IPv6 routers

Create /etc/radvd.conf file and set the following.

interface sha0
{
        AdvSendAdvert on;        # Sending router advertisements
        MinRtrAdvInterval 3;
        MaxRtrAdvInterval 10;
        prefix fec0:1::0/64      # Sending Prefix fec0:1::0/64 from sha0
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

Note

In the server that runs Fast switching mode, configure two or more router as IPv6 router. If the IPv6 router breaks down, it cannot use site-local address to communicate.
To prevent this, it is recommended to setup at least two IPv6 routers.
Depending on the version of radvd, kernel parameter(net.ipv6.conf.all.forwarding=1) must be defined in /etc/sysctl.conf file. For details on /etc/radvd.conf, refer to the radvd.conf(5), radvd(8) manual.

6) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now

1) Setting up the system

1-1) Define an address for takeover virtual IP and host name 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".

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

DEVICE=eth0
HWADDR=XX:XX:XX:XX:XX:XX

ONBOOT=yes
TYPE=Ethernet

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

DEVICE=eth1
HWADDR=XX:XX:XX:XX:XX:XX

1-3) When the system is RHEL, on the /etc/sysconfig/network file, define a statement allows the system to load IPv6 module.

NETWORKING=yes
NETWORKING_IPV6=yes
IPV6TO4INIT=no

interface sha0
{
        AdvSendAdvert on;        # Sending router advertisements

        MaxRtrAdvInterval 10;
        prefix fec0:1::0/64      # Sending Prefix fec0:1::0/64 from sha0
        {
                AdvOnLink on;
                AdvAutonomous on;

1) Configuration of userApplication: After configuring HOST-A, HOST-B and HOST-C, register the created takeover virtual interface as a Gls resource to create a cluster application. Use RMS Wizard to set up the cluster configuration. For details, see "PRIMECLUSTER Installation and Administration Guide".

2) Starting of userApplication: After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
