Secondary Tab for iSTAR Classic & iSTAR ProTable 1-11: Secondary Tab Fields, continuedField/ButtonWhile connected, declareconnection failure if nomessage for n secondsController activates thisevent while in connectionfailure:DescriptionSpecify the number of seconds that the controller and host wait for a connectionverification message before declaring a communications failure for the secondarypath. The controller and host send these messages to each other during periods oflow system activity to confirm that the secondary path is operating correctly. You canchoose 40 or 80 seconds.The value you specify in this field determines how often the connection verificationmessage is sent. If you specify 40 seconds, the message is sent every 10 seconds;if you specify 80 seconds, the message is sent every 20 seconds.For example, if you specify 40 seconds in this field, the controller receives aconnection verification message every 10 seconds during periods of low systemactivity. If the controller does not receive at least one message within 40 seconds, itdeclares the secondary path to be in communications failure.If a communications failure occurs, the following connections are attemptedsimultaneously:• The cluster tries to re-establish a connection with the host on the secondarycommunications path at the rate specified in the After connection failure,controller attempts to reconnect every XX seconds field in the Secondarytab.• The master attempts to re-connect to the host on the primary communicationspath at the rate specified in the After connection failure, controller attemptsto reconnect every XX seconds field in the Primary tab. The master tries toestablish a connection with the host forever or until a connection is established.• The master broadcasts a request across its subnet for the host’s IP Address. Ifthe iSTAR Configuration Utility is configured for auto-response, it responds tothe master. See the iSTAR Pro Installation and Configuration Guide forinformation.Enter the event that the controller activates when a communications failure occurson the secondary communications path. You can double-click on the field to displaya list of events.Specify an event that is located on the controller. If the event is located on anothercontroller, the system displays an error message.NOTE: This controller is responsible for secondary communications.1–52 C•CURE 800/8000 Hardware Configuration Guide
