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. Differences between primary and secondary volume tracks are recorded as noncompare tracks. A first predetermined time is waited for. A subsequent track-to-track comparison of the noncompare tracks is performed.
