B.7.6 Example of the Cluster system (No IP takeover)

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.

[HOST-A]

1) Setting up the system

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

192.168.80.1    hosta    # HOST-A Virtual IP
192.168.80.2    hostb    # HOST-B Virtual IP
192.168.80.100  swhub1   # Primary HUB IP
192.168.80.101  swhub2   # Secondary HUB IP

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

1-3) Define a statement to enable the network configuration in /etc/sysconfig/network file.

NETWORKING=yes

2) Creating a virtual interface

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

3) Setting an IP address and a subnet mask

Define an IP address or a subnet mask in /etc/sysconfig/network-scripts/ifcfg-sha0 file.

4) Setting the network monitoring function

/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p 192.168.80.100,192.168.80.101

5) Activating a virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

6) Creating a takeover virtual interface

/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0

[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.

2) Creating a virtual interface

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

3) Setting an IP address and a subnet mask

Define an IP address or a subnet mask in /etc/sysconfig/network-scripts/ifcfg-sha0 file.

4) Setting the network monitoring function

/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p 192.168.80.100,192.168.80.101

5) Activating a virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

6) Creating a takeover virtual interface

/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0

[Configuration by RMS Wizard]

1) Configuration of userApplication

After configuring HOST-A and HOST-B, register the created takeover virtual interface (sha0:65) 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.
