B.6.6 Example of the Cluster system (Mutual Standby) without NIC sharing

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

The xx 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".
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. Note that it is not necessary to define an IPv6 address, which automatically allocates address by the Stateless Address Autoconfiguration feature.

192.168.70.1    hosta   # HOST-A/B Virtual IP (Takeover IP1)
192.168.70.2    host11  # HOST-A Physical IP
192.168.70.3    host21  # HOST-B Physical IP
192.168.71.1    hostb   # HOST-A/B Virtual IP (Takeover IP2)
192.168.71.2    host12  # HOST-A Physical IP
192.168.71.3    host22  # HOST-B Physical IP
192.168.70.100  swhub1  # Primary HUB IP
192.168.70.101  swhub2  # Secondary HUB IP
192.168.71.100  swhub3  # Primary HUB IP
192.168.71.101  swhub4  # Secondary HUB IP
fec0:1::1       v6hosta    # HOST-A/B Takeover virtual IP
fec0:2::1       v6hostb    # HOST-A/B Takeover virtual IP

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1,2,3) 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".

[Configuration by RMS Wizard]

1) Configuration of userApplication: After configuring HOST-A and HOST-B, 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.
