Abstract
A method, device, and computer program product for performing asynchronous remote copy verification is provided. An initial track-to-track comparison between a primary and a secondary volume pair is performed. A first predetermined time is waited for. Upon completion of the first predetermined time, a subsequent primary volume track-to-secondary volume track comparison is performed only on the noncompare tracks. A query is performed for determining whether all of the noncompare tracks have been resolved. If any of the noncompare tracks have not been resolved, a query is performed for determining if a predetermined number of iterations of the primary volume track-to-secondary volume track comparison have been performed, and an additional subsequent primary volume track-to-secondary volume track comparison is performed only on unresolved noncompare tracks.
