Abstract: Control is switched from a first server to a second server in a fault tolerant system. The first and second servers are coupled with an expansion bus in an expansion box for communication with the expansion bus. An indication is provided to the second server to indicate the activity state of the first server. Communication between the first server and the expansion box is disabled if the indication indicates the first server is inactive. Communication between the second server and the expansion bus is disabled if the indication indicates that the first server is active. Communication between the second server is enabled if the indication indicates that the first server is inactive. The indication includes a heartbeat message transmitted periodically to the second server. The expansion bus includes a PCI bus.

Abstract translation: 控制从容错系统中的第一个服务器切换到第二个服务器。 第一和第二服务器与用于与扩展总线通信的扩展盒中的扩展总线连接。 向第二服务器提供指示以指示第一服务器的活动状态。 如果指示表明第一台服务器处于非活动状态，则第一台服务器和扩展盒之间的通信将被禁用。 如果指示表明第一台服务器处于活动状态，则第二台服务器和扩展总线之间的通信将被禁用。 如果该指示指示第一服务器不活动，则启用第二服务器之间的通信。 该指示包括周期性发送给第二服务器的心跳消息。 扩展总线包括一个PCI总线。
