In Huawei OceanStor hybrid flash storage, the data, logs, and modification information of a database application are stored in the primary LUDN1, primary LUN2, and primary LUN3 respectively, and asynchronous remote replication is created for the three primary LUNs. When the primary LUIN2 fails, the database can be started normally through the primary storage system after the data of the primary storage system is restored using the secondary storage system.
