| 发明名称 | Multiple hyperswap replication sessions | ||
| 摘要 | 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. | ||

| 主权项 | 1. A system comprising; a server; a first location including one or more storage systems in communication with the server, wherein at least one of the one or more storage systems at the first location includes a designation of a primary storage system and at least one of the one or more storage systems at the first location includes a designation of a secondary storage system; a second location including one or more storage systems in communication with the server, wherein at least one of the one or more storage systems at the second location includes the designation of the primary storage system and at least one of the one or more storage systems at the second location includes a designation of the secondary storage system; a link operable for providing communication between the one or more storage systems at the first location and the one or more storage systems at the second location; wherein the server comprises a HyperSwap manager for monitoring a plurality of HyperSwap sessions between the one or more storage systems at the first location and the one or more storage systems at the second location; wherein either the first location or the second location is designated as a preferred location; and wherein in response to detecting an error event the HyperSwap manager changes the designation of all of storage systems at the preferred location to the primary storage systems. | ||
