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

[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 4.1".

2) Starting of userApplication

After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
