Abstract:
For performing efficient management of tracks in an asynchronous Peer-to-Peer Redundant Copy (PPRC) operation in a computing storage environment, a correct status of a sequential bit is determined by examining a primary cache, where if data being transferred pursuant to the PPRC operation in a primary track remains in the primary cache, the sequential bit setting found therein is used.
