Abstract: For coordinated disaster recovery, a reconciliation process is performed for resolving intersecting and non-intersecting data amongst disaster recovery systems for takeover operations. An ownership synchronization process is coordinated for replica cartridges via the reconciliation process at the disaster recovery systems. The disaster recovery systems continue as a replication target for source systems and as a backup target for local backup applications.

Abstract: Communication is arrested between a source data entity and a replicated data entity at a location declared in a DR mode. The DR mode is negotiated to a central replication management component as a DR mode entry event. The DR mode entry event is distributed, by the central replication management component, to each member in a shared group. The DR mode is enforced using at least one replication policy.
Abstract translation: 通信在源数据实体和在DR模式下声明的位置的复制数据实体之间被阻止。 将DR模式协商为中央复制管理组件作为DR模式入口事件。 DR模式条目事件由中央复制管理组件分发给共享组中的每个成员。 使用至少一个复制策略强制实施DR模式。

Abstract: Visibility of a data storage entity on a first storage system is switched to a replicated data storage entity on a second storage system. Data from the data storage entity is replicated from the first storage system to the second storage system using a common serial number. The data storage entity is hidden from the first storage system by concealing the common serial number. An ejection of the data storage entity from the first storage system is automated, and the replicated data storage entity is introduced to the second storage system.
Abstract translation: 第一存储系统上的数据存储实体的可见性被切换到第二存储系统上的复制数据存储实体。 来自数据存储实体的数据使用公共序列号从第一存储系统复制到第二存储系统。 通过隐藏公共序列号，数据存储实体从第一存储系统隐藏。 从第一存储系统弹出数据存储实体是自动的，并且将复制的数据存储实体引入第二存储系统。

Abstract: A replication synchronization table (RST) is configured for the source instance. The RST is adapted for recording compacted information for at least one of a truncate and an erase operation applied on the source instance. The RST of the source instance is updated at a source component with the compacted information. The updated RST is transmitted from the source instance to the replicated instance. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined.
Abstract translation: 为源实例配置了复制同步表（RST）。 RST适于记录应用在源实例上的截断和擦除操作中的至少一个的压缩信息。 源实例的RST在具有压缩信息的源组件上更新。 更新的RST从源实例传输到复制实例。 基于源实例的RST和复制实例的RST，确定表示数据应发送到复制组件以实现完全同步的源组件上的最新位置的数据。

Abstract: Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances. Receipt of the synchronization message is acknowledged by the replicated component by sending a dirty state acknowledgement. If, during a subsequent recovery process, the dirty state is not yet cleared, the replicated component is deemed ineligible for participation in a full restoration operation.
Abstract translation: 在由源组件对源实例执行的存储操作之后，向复制实例的复制组件发送同步消息。 同步消息被本地存储在与源组件相关联的持久存储位置中，以及表示执行存储操作的时间的指示符。 根据复制组件接收到同步消息，将复制的组件更新为脏状态，以指示源和复制实例之间缺少完全同步。 复制组件通过发送脏状态确认来确认同步消息的接收。 如果在后续的恢复过程中，脏状态尚未被清除，则认为复制的组件不符合参与完全恢复操作的资格。
