| 发明名称 | Maintenance of a fabric priority during synchronous copy operations | ||
| 摘要 | A primary storage controller receives a write command from a host, wherein Fibre Channel frames corresponding to the write command have a priority indicated by the host. The primary storage controller performs a synchronous copy operation to copy data written by the write command from the primary storage controller to a secondary storage controller, wherein Fibre Channel frames corresponding to the synchronous copy operations have an identical priority to the priority indicated by the host. | ||

| 主权项 | 1. A method, comprising: receiving, by a primary storage controller, a write command from a host, wherein Fibre Channel frames corresponding to the write command have a priority indicated by the host; and performing, by the primary storage controller, a synchronous copy operation to copy data written by the write command from the primary storage controller to a secondary storage controller, wherein Fibre Channel frames corresponding to the synchronous copy operation have an identical priority to the priority indicated by the host. | ||
