Designing a system configurationNetwork configurationThe cluster configuration cannot be configured or operated in an environment, such as NAT, wherean IP address of a local server is different from that of a remote server.Example of network configurationExternal networkNAT deviceInternal network10.0.0.2192.168.0.210.0.0.1NAT device settingsA packet to 10.0.0.2 fromexternal is forwarded192.168.0.1Server1 cluster settingsLocal server :10.0.0.1Remote server:10.0.0.2Server2 cluster settingsLocal server :192.168.0.1Remote server:10.0.0.1The configuration that IP addresses oflocal and remote servers are different isnot allowed.Execute Script before Final Action setting for monitor resourcerecovery actionExpressCluster version 3.1.0-1 and later supports the execution of a script before reactivation andbefore failover.The same script is executed in either case. Therefore, if Execute Script before Final Action is setwith a version earlier than 3.1.0-1, editing of the script file may be required.For the additional script configuration needed to execute the script before reactivation and beforefailover, the script file must be edited to assign processing to each recovery action.For the assignment of processing for a recovery action, see "Recovery/pre-recovery action script"in Chapter 5, "Monitor resource details" in the Reference Guide.Section II Installing ExpressCluster113
