摘要： A method for establishing bilateral communications over a single ESCON link coupling a pair of control units. The method steps include (a) permitting link address acquisition between directly connected link-level facilities that simultaneously assume the role of a master control unit in a peer-to-peer remote copy (PPRC) configuration, (b) resolving conflicting device-level frames that initiate a path to a device (also termed an I/O connection), and (c) dynamically determining the role assumed by a link-level facility (master or slave) when a single logical path is shared.

摘要： A peer-to-peer backup storage system automatically switches from a primary storage site to a mirrored backup site in response to a primary site failure, where the secondary site then honors any existing host initiated reservation of primary storage. Each site includes a storage controller and storage, where the primary site receives and stores data and forwards the received data to the secondary site for storage to mirror contents of primary storage. The primary and secondary sites are coupled to one or more hosts. Whenever the primary controller receives a reserve request from a host, it reserves the primary storage (or a subpart thereof) for the exclusive use of the reserve-initiating host. This may involve, for example, the primary controller storing a path group ID that identifies the reserving host. The primary controller also notifies the secondary controller of the reservation, e.g., sending the path group ID involved in the reservation operation to the secondary site. Responsive to a primary site failure, the system performs “switch” operation where the system stops forwarding data from the primary site to the secondary site. Furthermore, the secondary site is operated in substitution for the primary site, to receive and store data from the hosts. Importantly, the secondary site honors the existing reservation of the primary storage by reserving the secondary storage to the first reserve-initiating host.
摘要翻译：点对点备份存储系统会自动从主存储站点切换到镜像备份站点，以响应主站点故障，其中辅助站点然后对任何现有主机启动的主存储预留进行授权。每个站点都包括一个存储控制器和存储，其中主站点接收并存储数据，并将接收到的数据转发到辅助站点以存储以镜像主存储器的内容。主站点和辅站点耦合到一个或多个主机。每当主控制器从主机接收到保留请求时，它将保留主存储器（或其子部分），用于备用启动主机的独占使用。这可能涉及例如主控制器存储标识保留主机的路径组ID。主控制器还向辅助控制器通知预约，例如将预约操作中涉及的路径组ID发送到辅助站点。响应于主站点故障，系统执行“切换”操作，系统停止将数据从主站点转发到辅助站点。此外，辅助站点的操作代替主站点，从主机接收和存储数据。重要的是，辅助站点通过将辅助存储预留到第一储备发起主机来表现主存储的现有预留。

摘要： A data storage system atomically suspends multiple duplex pairs across either a single storage subsystem or multiple storage subsystems. The duplex pairs are suspended such that the data on the secondary DASDs of the duplex pairs is maintained in a sequence consistent order. A host processor in the data storage system running an application generates records and record updates to be written to the primary DASDs of the duplex pairs. The storage controller directs copies of the records and record updates to the secondary DASDs of the duplex pairs. Sequence consistency is maintained on the secondary DASDs by quiescing the duplex pairs and then suspending the duplex pairs with change recording. Quiescing the duplex pairs allows any current write I/O in progress to complete to the primary DASD. The storage controller then locks out any subsequent write I/O from the host processor by raising a long busy signal to such subsequent write requests. Suspending the duplex pairs with change recording directs the storage controller to mark the physical address of the primary DASD which the application in the host processor updates between the time the duplex pair is suspended and then is reestablished.
