Abstract
A method includes monitoring a plurality of HyperSwap sessions between one or more storage systems located at a first location and one or more storage systems located at a second location, wherein at least one of the one or more storage systems located at the first location and at the second location are designated as a primary storage system. The method includes detecting an error event and freezing communications between the storage systems located at the first location and the second location in response to the error event. The method also includes designating either the first location or the second location as a preferred location and modifying the designation of all of storage systems at the preferred location to be primary storage systems in response to the error event.
