    • A method, system, and article of manufacture for recovering from a track format error detected by a host computer associated with a storage controller associated with a storage disk array. The recovery method begins with saving a copy of the track format information associated with the data track that triggered the track format error in a predetermined location. Next, the track format information associated with the data track that caused the error is invalidated and the subject data is restaged. Subsequently, the restaged data is compared to the saved copy of the track format information to determine if the track format error exists with respect to the restaged data. If the track format error is detected with respect to the restaged data, the method further consists of reconstructing the data, preferably by performing a reconstruct read recovery. The reconstructed data is then compared to the saved copy of the track format information to determine if the track format error exists with respect to the reconstructed data. The method is completed by rebuilding the track format information to match the reconstructed data, writing the reconstructed data to the storage disk array, and passing the reconstructed data to the host.
    • 用于从与存储盘阵列相关联的存储控制器相关联的主计算机检测到的轨道格式错误中恢复的方法,系统和制品。 恢复方法开始于保存与在预定位置触发轨道格式错误的数据轨道相关联的轨道格式信息的副本。 接下来,与导致错误的数据轨道相关联的轨道格式信息被无效并且主题数据被重新调用。 随后,将重新分配的数据与保存的轨道格式信息的副本进行比较,以确定相对于重新分配的数据是否存在轨道格式错误。 如果相对于再分页数据检测到轨道格式错误,该方法还包括重建数据,优选地通过执行重构读取恢复。 然后将重建的数据与保存的轨道格式信息的副本进行比较,以确定相对于重构数据是否存在轨道格式错误。 该方法通过重建跟踪格式信息以匹配重构数据,将重建的数据写入存储盘阵列,并将重建的数据传送到主机来完成。

    • A dual cluster storage server maintains track control blocks (TCBs) in a data structure to describe the data stored in cache in corresponding track images or segments. Following a cluster failure and reboot, the surviving cluster uses the TCBs to rebuild data structures such as a scatter table, which is a hash table that identifies a location of a track image, and a least recently used (LRU)/most recently used (MRU) list for the track images. This allows the cache data to be recovered. The TCBs describe whether the data in the track images is modified and valid, and describe forward and backward pointers for the data in the LRU/MRU lists. A separate non-volatile memory that is updated as the track images are updated is used to verify the integrity of the TCBs.
    • 双集群存储服务器维护数据结构中的轨道控制块(TCB)以描述存储在相应轨道图像或段中的高速缓存中的数据。 在集群故障和重新启动之后,幸存的集群使用TCB来重建数据结构,例如分散表,其是标识轨迹图像的位置的哈希表,以及最近最少使用的(LRU)/最近使用的 MRU)轨道图像列表。 这样可以恢复高速缓存数据。 TCB描述轨道图像中的数据是否被修改和有效,并描述LRU / MRU列表中的数据的前向和后向指针。 随着跟踪图像被更新而更新的单独的非易失性存储器用于验证TCB的完整性。

    • Disclosed are a storage controller, and a method of operating a storage controller, for interfacing between host systems and a storage devices system. The storage controller includes a first cluster including a first processor and a first cache, and a second cluster including a second processor and a second cache. The method comprises the step of directing data from the host systems through first and second data paths to the storage system. The first processor and cache are associated with the first data path, and the second processor and cache are associated with the second data path. Under one set of conditions, the controller enters a failover mode, wherein data directed to the first data path are routed to the second data path. Under another set of conditions, the controller deconfigures the first cache without entering the failover mode.

    • An apparatus, system, and method are disclosed for data tracking and, in particular, for facilitating failure management within an electronic data communication system. The apparatus includes a tracking module and an error analysis module. The tracking module stores an adapter identifier in a tracking array. The adapter identifier corresponds to a source adapter from which data is received. The error analysis module determines a source of a data failure in response to recognition of the data failure. The data failure may occur on a host adapter, a device adapter, a communication fabric, a multi-processor, or another communication device. The apparatus, system, and method may be implemented in place of or in addition to hardware-assisted data integrity checking within a data storage system.

    • Method for selectively clearing persistent data such as metadata in a storage subsystem. The method includes identifying one or more metadata tracks to clear, receiving a request from a client to clear the identified metadata tracks, passing the request to a storage device driver, and clearing the identified metadata tracks. The metadata tracks to be cleared may be identified by a specific storage function associated with the metadata to be cleared or by a specific storage target associated with metadata. Alternatively, both a storage function and a storage target may be specified. Preferably, the request to clear one or more identified metadata tracks may be executed without affecting unrelated storage functions. In addition, the request may be executed while preserving metadata tracks unrelated to the identified metadata tracks. Thus, execution of a request to selectively clear identified global metadata tracks in accordance with the present invention will typically not cause the loss of configuration information and will not necessitate a reboot of the system. In addition, a request as described above may be executed at any point in time while the storage system is running.
    • 用于选择性地清除诸如存储子系统中的元数据的持久性数据的方法。 该方法包括识别一个或多个元数据轨道以清除,接收来自客户端的请求以清除所识别的元数据轨道,将请求传递到存储设备驱动器,以及清除所识别的元数据轨道。 要清除的元数据轨迹可以通过与要清除的元数据或与元数据相关联的特定存储目标相关联的特定存储功能来识别。 或者,可以指定存储功能和存储目标。 优选地,可以执行清除一个或多个所识别的元数据轨道的请求而不影响不相关的存储功能。 此外,可以在保留与所识别的元数据轨道无关的元数据轨道的同时执行请求。 因此,根据本发明的执行选择性地清除所标识的全局元数据轨迹的请求通常不会导致配置信息的丢失,并且不会使系统重新启动。 此外,当存储系统运行时,可以在任何时间点执行如上所述的请求。
