B.8.1 Example of the Single system

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 the GS configuration, refer to GS manual.

[HOST-A]

1) Setting up the system

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

192.168.70.1    host11   # HOST-A Physical IP
192.168.71.1    host12   # HOST-A Physical IP
192.168.80.1    hosta    # HOST-A Virtual IP
192.168.80.254  virgw    # Virtual gateway
192.168.70.2    gs11     # GS-1 Physical IP(IP-1)
192.168.71.2    gs12     # GS-1 Physical IP(IP-2)
192.168.81.2    gsa      # GS-1 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".

1-3) When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

NETWORKING=yes

1-4) Set the static route information of the virtual gateway for the remote host's virtual IP address in /etc/sysconfig/network-scripts/route-"interface name".

2) Reboot

Run the following command to reboot the system. After rebooting the system, verify eth0 and eth1 are active using ifconfig command.

/sbin/shutdown -r now

3) Setting a subnet mask

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0

4) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m c -i 192.168.80.1 -t eth0,eth1

5) Setting the Communication target monitoring function

/opt/FJSVhanet/usr/sbin/hanetobserv create -n GS-1 -i 192.168.81.2 -t 192.168.70.2,192.168.71.2

6) Setting a virtual gateway

/opt/FJSVhanet/usr/sbin/hanetgw create -n sha0 -g 192.168.80.254

7) Activating of virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

[GS-1]

Set the information for HOST-A's physical IP address and virtual IP address. For information on how to do this, see the GS manual.
