Some files require that the dual controllers can access the same data unit (LUN) at the same time. However, Huawei dual controllers cannot access the same data unit (LUN) at the same time.

Good day!

Controllers are connected to each other. LUNs belong to different controllers. If a controller is faulty, the LUNs managed by the controller are accessed by another controller (it is called peer access). The cache data of the two controllers is mirrored.
