Abstract:
Provided are a computer program product, system, and method for receiving, at a secondary storage controller, information on modified data from a primary storage controller to use to calculate parity data. The secondary storage controller receives from the primary storage controller difference data calculated from modified data and a pre-modified version of the modified data for a primary group of tracks at the primary storage and one of the modified data and new primary parity data calculated at the primary storage controller from the modified data and the difference data. The secondary storage controller uses the difference data and one of the modified data and the new primary parity data to write new secondary parity data and the modified data to a secondary group of tracks at the secondary storage.

Claim (Index 21):
The method of  claim 17 , further comprising:\n receiving the difference data and the new primary parity data from the primary storage controller; calculating the new secondary parity data from data for the secondary group of tracks from all data for the secondary group of tracks in a secondary cache at the secondary storage controller and the received difference data; comparing the new secondary parity data and the new primary parity data; validating transfers from the primary storage controller in response to determining that new secondary parity data and the new primary parity data match; and throwing an exception in response to determining that new secondary parity data and the new primary parity data do not match.
