Abstract
Provided are a computer program product, system, and method for recovering a volume table and data sets from a corrupted volume. Data corruption is detected in a volume having data sets. A volume table having information on the data sets allocated in the volume is diagnosed. A backup volume table comprising a most recent valid backup of the volume table is accessed from a backup of the volume in response to determining that the diagnosed volume table is not valid. Content from the backup volume table is processed to bring to a current state in a recovery volume table for a recovery volume. The data sets in the volume are processed to determine whether they are valid. The valid data sets are moved to the recovery volume. A data recovery operation is initiated for the data sets determined not to be valid.
