Recovering a volume table and data sets from a corrupted volume

A system in communication with a storage, comprising:

• a processor;
• and
• a computer readable storage medium having computer readable program code embodied therein executed by the processor to perform operations, the operations comprising:
• detecting data corruption of a volume having data sets in the storage;
• diagnosing a volume table having information on the data sets allocated in the volume to determine whether the volume table is valid, wherein the volume table is used to determine the data sets in the volume;
• accessing a backup volume table comprising a most recent valid backup of the volume table from a backup of the volume in response to determining that the diagnosed volume table is not valid;
• processing content from the backup volume table to bring to a current state in a recovery volume table for a recovery volume;
• processing the data sets in the volume to determine whether they are valid;
• moving the valid data sets to the recovery volume;
• and
• initiating a data recovery operation for the data sets determined not to be valid.

A method for handling data corruption, comprising:

• detecting data corruption of a volume having the data sets in a storage device;
• diagnosing a volume table having information on the data sets allocated in the volume to determine whether the volume table is valid, wherein the volume table is used to determine the data sets in the volume;
• accessing a backup volume table comprising a most recent valid backup of the volume table from a backup of the volume in response to determining that the diagnosed volume table is not valid;
• processing content from the backup volume table to bring to a current state in a recovery volume table for a recovery volume;
• processing the data sets in the volume to determine whether they are valid;
• moving the valid data sets to the recovery volume;
• and
