Abstract
An approach to providing auto recovery of data sets in volumes. When an error condition results from an attempt to access an unintentionally deleted data set, an event is generated and sent to other systems with access to the volume in which the data set existed. The volume is also locked to prevent corruption during the recovery process. A system that has the unintentionally deleted data set open retrieves location information for the data set from control blocks in the system's memory. This location information is used to build a new entry for the data set in the VTOC for the volume. When the data set is thus recovered, the data set is validated, the lock removed, and the data set is made available to the systems sharing the volume.
