[Configuration by RMS Wizard]
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".
After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
[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.
