Abstract:
In one aspect of the present description, a primary-secondary role swap operation which swaps roles of primary and secondary data storage systems in a distributed data storage system, is synchronized with safe data commit scan operations of individual data storage systems. The safe data commit scan operations of the individual data storage systems are also synchronized to ensure completion of the safe data commit scans and to reduce the occurrence of reductions in input/output (I/O) response times prior to initiation of a primary-secondary role swap operation. Other features and aspects may be realized, depending upon the particular application.

Claim (Index 7):
The method of  claim 3  wherein the first data storage system is a master data storage system and the second data storage system is a subsidiary data storage system, and the synchronizing the first plurality of safe data commit scan operations further includes:\n sending a second start safe data commit scan operation message from the master data storage system to another subsidiary data storage system; \n in response to the second start safe commit scan operation message, initiating a third safe data commit scan operation of the first plurality of safe data commit scan operations in another subsidiary data storage system; \n following completion of the third safe data commit scan operation of the first plurality of safe data commit scan operations in another subsidiary data storage system, sending directly to the master data storage system a completion message indicating completion of the third safe data commit scan operation in another subsidiary data storage system; and \n in response to completion messages received directly from subsidiary data storage systems indicating completion of safe data commit scan operations in the subsidiary data storage systems, swapping roles of the first and second data storage systems such the second data storage system is reconfigured as a primary data storage system and the first data storage system is reconfigured as a secondary data storage system.
