摘要： A method for a multiple port host to communicate with multiple tape drives is provided by requesting information associated with a particular tape. Information is provided that is indicative of availability status of a plurality of host ports. It is determined if there is a traffic load or a reservation load on an active host port. The active host port is reserved if there is not a traffic load or a reservation load on the active host port. Another method receives input indicative of read/write information from at least one tape drive at a host bus adapter. A host port count is increased, and a size of the read/write information is increased until the read/write information is not accepted by the host bus adapter. The host port count is decreased, and the size of the read/write information is decreased until the read/write information is accepted.
摘要翻译：通过请求与特定磁带相关联的信息来提供多端口主机与多个磁带驱动器通信的方法。提供了指示多个主机端口的可用性状态的信息。确定活动主机端口上是否存在流量负载或预留负载。如果活动主机端口上没有流量负载或预留负载，则保留活动主机端口。另一种方法从主机总线适配器接收来自至少一个磁带驱动器的指示读/写信息的输入。增加主机端口计数，并且增加读/写信息的大小，直到主机总线适配器不接受读/写信息。主机端口计数减少，读取/写入信息的大小减小，直到读取/写入信息被接受为止。
