[Configuration by RMS Wizard]
After completing the procedure 7) for HOST-A and HOST-B, use the RMS Wizard to set up the cluster environment.
Select the SysNode for HOST-A and HOST-B when creating GLS resources, and then register the created GLS resources with the cluster applications.
When registering the GLS resources with the cluster applications, select the SysNode for HOST-A and HOST-B in order of the operation node and the standby node, and then register the takeover IP address "192.168.80.1".
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.
