Abstract: A method can include obtaining catalog data of a catalog. The catalog can include one or more records. The method can further include detecting one or more damaged records among the one or more records and isolating the one or more damaged records. The method can further include identifying one or more undamaged records among the one or more records. The method can further include transferring the one or more undamaged records to a backup catalog. The method can further include obtaining a transfer status of a first undamaged record of the one or more undamaged records. The method can further include obtaining an access request corresponding to the first undamaged record. The method can further include determining, based on the transfer status, a response to the access request and generating, based at least in part on the backup catalog, a restored catalog.

Abstract: A method for analyzing data corruption is disclosed. In one embodiment, such a method includes identifying a data set to analyze for data corruption. This data set resides on tracks of a volume. The method further determines, from control information associated with the volume, on which tracks of the volume the data set resides. The method reads content of the data set without opening the data set by performing full-track reads of the tracks. The method further determines an expected format of the content by analyzing the control information. An actual format of the content is compared to the expected format to identify areas of the data set that may be corrupt. A corresponding system and computer program product are also disclosed.

Abstract: Provided are a computer program product, system, and method for an application to provide for, in one embodiment, using hierarchical storage management to respond to a request to delete a data set by migrating the data set to another storage tier in a storage system before deleting the data set from its current location. As a result, the data set is stored on another tier to provide an opportunity to reverse the decision to delete the data set. In one embodiment, a temporary interval of time is provided to reverse the deletion decision and restore the data set from the migrated data set, before the data set is permanently deleted.

Abstract: Provided are a computer program product, system, and method for determining when to release a lock from a first task holding the lock to grant to a second task waiting for the lock. A determination is made as to whether a holding of a lock to the resource by a first task satisfies a condition and whether the lock is swappable. The lock is released from the first task and granted to a second task waiting in a queue for the lock in response to determining that the holding of the lock satisfies the condition and that the lock is swappable. The first task is indicated in the queue waiting for the lock in response to granting the lock to the second task.

Abstract: A method of and system for opening a data set is disclosed. The method and system may include structuring a storage facility to have address spaces. The address spaces may include a first address space having an open manager. The open manager may be configured and arranged to manage activities associated with an open request in response to receiving the open request. The method and system may include performing pseudo-opens associated with the open request in the address spaces. The method and system may include performing a batch-open utilizing the pseudo-opens and a resource used to complete the open request.

Abstract: Provided are a computer program product, system, and method for using an alias volume name for a volume to allocate space to a data set. An assignment of a plurality of volumes to a data set is maintained, wherein the volumes are configured in a storage system. A request is received to extend the data set. An alias volume name is assigned to the data set for a previously assigned volume to the data to extend the data set in response to one of the previously assigned volumes having available space to extend the data set. A base volume name is assigned to the data set for a volume not assigned to the data set in response to one of the previously assigned volumes to the data set not having available space to extend the data set.
