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 releasing the storage segments prior to completely reformatting the storage volume and subsequently incrementing the global counter such that the global counter and each segment counter no longer match at a subsequent time. The method further includes enabling a user to write data to the storage segments prior to completely reformatting the storage volume in response to incrementing the global counter. 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： Method, system, and computer program product embodiments for throttling storage initialization for data destage in a computing storage environment are provided. An implicit throttling operation is performed by limiting a finite resource of a plurality of finite resources available to a background initialization process, the background initialization process adapted for performing the storage initialization ahead of a data destage request. If a predefined percentage of the plurality of finite resources is utilized, at least one of the plurality of finite resources is deferred to a foreground process that is triggered by the data destage request, the foreground process adapted to perform the storage initialization ahead of a data destage performed pursuant to the data destage request. An explicit throttling operation is performed by examining a snapshot of storage activity occurring outside the background initialization process.

摘要： Deleting a data volume from a storage system and freeing its storage space to make it available to be allocated to a new volume is accomplished by only zeroing associated metadata for the tracks contained in the freed storage space which is then reused in a new volume allocation and an attempt is made by the new volume to read a first record R0 of a track. A determination is made as to whether a first user record R1 of the volume is stale If the first record R0 is stale. If record R1 is stale, the metadata or track format description (TFD) is modified whereby the entire track is indicated as being uninitialized and the first record R0 is uninitialized. If record R1 is not stale, the first record R0 is regenerated and the TFD is modified whereby the entire track is indicated as being initialized.

摘要： System, computer program product, and method embodiments for communication between a kernel operational on a storage subsystem and a key manager (KM) through a hardware management console (HMC) to provide encryption support are provided. In one embodiment, an event request is initiated by the kernel to the KM to execute an event flow. Pursuant to a communication request by the kernel to the HMC, a socket of the HMC is opened along a communication path between the KM and the kernel according to an event flow type selected by the KM for the event flow. Pursuant to a data request by the kernel to the KM, data including a data payload is sent by the KM to the kernel, the data payload corresponding to the selected event flow type.

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： A method for migrating volumes in a storage system includes identifying an extent of data (belonging to a volume) requiring migration from a source extent to a target extent. The method allocates a selected number of copiers to the extent of data to migrate the extent of data from the source extent to the target extent. Each copier is configured to copy a unit of data, which is a smaller division of the extent of data. The method monitors destages (i.e., writes) that occur to the source extent as the copiers migrate the extent of data from the source extent to the target extent. In the event the destages occur faster than the copiers can copy units to the target extent, the method allocates additional copiers to the extent of data to assist in migrating the extent of data. A corresponding apparatus and computer program product are also disclosed.
