摘要： Various embodiments for storage initialization and data destage in a computing storage environment are provided. At least a portion of data on a storage device is initialized using a background process, while one of simultaneously and subsequently destaging the at least the portion of the data to the storage device using a foreground process is performed. A persistent metadata bitmap, adapted to indicate whether the at least the portion of the data has been initialized, is staged to cache, the cache operable in the computing storage environment. The background process maintains a volatile bitmap indicating a status of the initialization of the at least the portion of the data in direct correspondence to the metadata bitmap. As the background process initializes the at least the portion of the data, an applicable bit on the persistent metadata bitmap is cleared and a corresponding bit is set on the volatile bitmap.

摘要： Methods, systems, and computer storage mediums including a computer program product method for formatting storage volumes are provided. One method includes creating a storage volume including a global counter and partitioned into multiple storage segments including a segment counter and partitioned into multiple stripes, wherein the global counter and each segment counter match at an initial time. The method further includes receiving a command to write data to a first stripe, comparing a first segment counter associated with the segment, determining if the segment and global counters match, and re-initializing first metadata associated with the segment to indicate the first segment requires formatting if the counters do not match. One system includes a processor for performing the above method and one computer storage medium includes a computer program product configured to perform the above method.

摘要： A secondary storage controller determines one or more tracks of one or more volumes in which data loss has occurred in the secondary storage controller. The secondary storage controller suspends a peer to peer remote copy operation between the secondary storage controller and a primary storage controller. Information on the one or more tracks of the one or more volumes in which the data loss has occurred is transmitted to the primary storage controller.

摘要： Systems and methods for initializing a memory system are provided. One system includes a processor and a memory including a storage volume coupled to the processor. The storage volume includes a first bitmap for tracking an initialization process for the storage volume and a second bitmap for tracking a copying process for the storage volume. A method includes performing, via the processor, an initialization process for the storage volume and tracking, via the processor utilizing the first bitmap, the initialization process. The method further includes performing, via the processor, a copying process for the storage volume prior to completing the initialization process and tracking, via the processor utilizing the second bitmap, the copying process. Also provided are computer storage mediums including computer program code for performing the above method.

摘要： Provided are a computer program product, system, and method for using queues corresponding to attribute values and priorities associated with units of work and sub-units of the unit of work to select the units of work and their sub-units to process. There are a plurality of work unit queues, wherein each of the work unit queues are associated with different work unit attribute values that are associated with units of work, wherein a plurality of the work unit queues include records for units of work to process having work unit attribute values associated with the work unit attribute values of the work unit queues, and wherein the work unit queues are each associated with a different priority. A record for a unit of work to perform is added to the work unit queue associated with a priority and work unit attribute value associated with the work unit.
