摘要： 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.

摘要： A method to rebuild an NVS image is disclosed. The method provides information to a first cluster of an information storage and retrieval system, and writes that information to a non-volatile storage device disposed in a second cluster. Upon losing utility power to all or part of the information storage and retrieval system, the method provides back-up power to a processor and a data cache, and determines if the information written to the second non-volatile storage device is accessible. If the information written to the second non-volatile storage device is accessible, then the method copies the image of that second non-volatile storage device to an external storage device. If the information written to said second non-volatile storage device is not accessible, then the method creates a virtual NVS image using the information disposed in a local data cache, and copies that virtual NVS image to an external storage device.

摘要： 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.
摘要翻译：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。

摘要： A mechanism is provided for a non-root-level user to execute command line script files via a generic command line interface. A command line interface in the data processing system receives a shellscript command from a non-root-level user via a client system. A security module in the data processing system determines whether the non-root-level user is logged on at a command line interface shell level access. Responsive to the non-root-level user being logged on at the command line interface shell level access, a storage controller at the request of a command line interface identifies a script file associated the shellscript command in a storage of the data processing system. The storage controller executes the script file and the command line interface sends the results of the execution of the script file to the non-root-level user via the client system.

摘要： Methods are provided for detecting and correcting dropped writes in a storage system. Data and a checksum are written to a storage device, such as a RAID array. The state of the data is classified as being in a “new data, unconfirmed” state. The state of written data is periodically checked, such as with a timer. If the data is in the “new data, unconfirmed” state, it is checked for a dropped write. If a dropped write has occurred, the state of the data is changed to a “single dropped write confirmed” state and the dropped write error is preferably corrected. If no dropped write is detected, the state is, changed to a “confirmed good” state. If the data was updated through a read-modified-write prior to being checked for a dropped write event, its state is changed to an “unquantifiable” state.
