摘要： Embodiments of the present invention provide a system and method for handling unit attentions. According to one embodiment of the present invention, a copy manager can receive an extended copy command and can issue a unit attention clearing command, such as the test unit ready command, to the source and destination devices listed in the extended copy command. The copy manager can further issue read commands to the source device and write commands to the destination device to copy data from the source device to the destination device according to the extended copy command.
摘要翻译：本发明的实施例提供了一种用于处理单元注意力的系统和方法。根据本发明的一个实施例，复制管理器可以接收扩展复制命令，并且可以向扩展复制命令中列出的源和目标设备发出诸如测试单元就绪命令的单元注意清除命令。复制管理器可以进一步向源设备发出读取命令，并将命令写入到目标设备，以根据扩展复制命令将数据从源设备复制到目标设备。

摘要： Systems and methods for reducing the number of unit attentions provided to a set of initiator devices by eliminating unnecessary unit attentions from queues in which unit attentions for each of the initiator devices are stored. In one embodiment, a system comprises a processor and a memory implemented in a router that is coupled between a target device and multiple initiator devices. As each unit attention is generated by the target device, it is forwarded to the initiator device that prompted the unit attention, and is stored in a queue for each of the other initiator devices. Periodically, the queues are examined to determine whether any of the unit attentions stored therein are unnecessary. One or more of the unit attentions that are determined to be unnecessary may be eliminated from the respective queues, reducing the number of unit attentions that are provided to the respective initiator devices.
摘要翻译：通过从每个发起者设备的单元注意的队列中消除不必要的单元注意来减少提供给一组发起者设备的单元注意的数量的系统和方法。在一个实施例中，系统包括处理器和在路由器中实现的存储器，其耦合在目标设备和多个启动器设备之间。由于目标设备生成每个单元注意事项，因此将其转发给提示单元注意的启动器设备，并存储在其他启动器设备的每个队列中。定期检查队列以确定其中存储的任何单位注意是否是不必要的。可以从相应的队列中消除被确定为不必要的单位注意中的一个或多个，减少了提供给各个发起者设备的单元注意的数量。

摘要： Systems and methods for performing error recovery in a system utilizing redundant communication links. In one embodiment, a host device is coupled to a sequential device such as a tape drive by a pair of Fibre Channel links. The host is configured to associate an identifier with each command. Upon detecting a failure of the transmission of the command via the first link, the host re-transmits the command via the second link. When the link failure is detected, the status of the last command transmitted before the failure is requested. After receiving the status of the command, a request that recovery start (possibly at a point indicated by the status information) is transmitted to the sequential device. If the recovery request is accepted, performance of the command is completed.
摘要翻译：在利用冗余通信链路的系统中执行错误恢复的系统和方法。在一个实施例中，主机设备通过一对光纤通道链路耦合到顺序设备，例如磁带机。主机被配置为将标识符与每个命令相关联。一旦检测到经由第一链路发送命令的故障，主机经由第二链路重发命令。当检测到链路故障时，请求在发生故障之前发送的最后一个命令的状态。在接收到命令的状态之后，向顺序设备发送恢复开始（可能在由状态信息指示的点）的请求。如果恢复请求被接受，命令的执行完成。

摘要： Embodiments of a routing device for coordinating the interoperability of devices with varying capabilities that send and/or receive commands in a storage network are disclosed. A host device in the storage network may inquire the capabilities of a storage device in a storage network. A routing device may receive a response from the storage device and pass the response through to the host unaltered or may alter the response to reflect the higher or lower capabilities of the routing device before sending the response to the host.
摘要翻译：公开了用于协调在存储网络中发送和/或接收命令的变化能力的设备的互操作性的路由设备的实施例。存储网络中的主机设备可以查询存储网络中的存储设备的能力。路由设备可以从存储设备接收响应，并将响应传递给主机，或者可以改变响应，以在将响应发送到主机之前反映路由设备的更高或更低能力。
