摘要：
Provided are a method, system, and article of manufacture, wherein a primary control unit sends a selected time to a plurality of secondary control units. Clocks are periodically synchronized at the primary control unit and the secondary control units with a time server. The primary control unit and the plurality of secondary control units consistently update secondary storage subsystems coupled to the plurality of secondary control units at the selected time.
