3.1.3 Operations in a cluster system
Regardless of the platform (OS and cluster software type) being used, to operate JP1/IM - Manager of a logical host in a cluster system, use the cluster software controls to start JP1/IM - Manager.
In a cluster system, applications are registered in the cluster software and are started and stopped by the cluster software; therefore, these applications are executed by the executing server and moved to the standby server through a failover when an error such as a system failure occurs. When you operate JP1/IM - Manager in a cluster operation system, you must also register JP1/IM - Manager in the cluster software so that the cluster software controls it.
When JP1/IM - Manager is running in a cluster operation system, it must be started and stopped by cluster software operations. If you start or stop JP1/IM - Manager manually, such as by executing a command, the status of the JP1/IM - Manager being managed by the cluster software will not match the actual status, which may be judged as an error.
For details about the start sequence, see 7.4 Registering into the cluster software during new installation and setup (for Windows) or 8.4 Registering into the cluster software during new installation and setup (for UNIX) in the JP1/Integrated Management 2 - Manager Configuration Guide.
