3.21.1 How JP1/IM - Service Support behaves when a failover occurs
When processing on the active server fails over to the standby server due to a failure, the cluster software stops all JP1/IM - Service Support services on the active server, and starts the same services on the standby server. At this time, the web browser (Internet Explorer) is disconnected from JP1/IM - Service Support, and becomes unable to display any JP1/IM - Service Support pages.
To display JP1/IM - Service Support pages after failover, you must log in to JP1/IM - Service Support again.
