In the following description of the asynchronous remote replication of the OceanStor V3 storage array, which one is wrong?

When adding a secondary LUN for asynchronous remote replication, the system automatically creates and activates the snapshot of the primary and secondary LUNs.

During asynchronous remote replication, after the master LUN write I/O is successful, the master array returns the write I/O success to the host.

After creating an asynchronous remote replication relationship, you need to do an initial synchronization.

When adding a secondary LUN for asynchronous remote replication, the system automatically creates and activates the snapshot of the primary and secondary LUNs.
