1. A method for analyzing a mainframe system having a hierarchical storage unit for sensitive information, comprising:
- receiving a request to analyze a first data set of records from the mainframe system;
determining that the first data set of records has been migrated by the hierarchical storage unit from a first source to a second source by operation of the mainframe system;
recalling the first data set of records from the second source to the first source;
reading the first data set of records from the first source;
inferring structure in at least one of a plurality of records of the first data set to define fields in the at least one of the plurality of records;
analyzing the fields for sensitive information; and
re-migrating the first data set of records to the second source responsive to the completion of the analysis.

Abstract
Examples of methods, systems, and computer-readable media for detection of sensitive information on hierarchical storage management mainframes are described using multiple techniques. The techniques may include determining if data has been migrated from a first storage medium to a second storage medium, recalling the migrated data from a second storage medium to the first storage medium, reading the migrated data, then re-migrating the data to the second storage medium.
