Title: DATA PROCESSING METHOD AND RELATED STORAGE APPARATUS
Abstract:
A data processing method, comprising: a first storage apparatus receiving a first reservation preemption command sent by a host via a target port, the first reservation preemption command comprising a port identifier of the target port, a reservation key to be validated and a LUN; determining a forwarding port corresponding to the target port according to a preset port mapping relationship, combining the reservation key to be validated, the LUN, the port identifier of the target port and a port identifier of the forwarding port to obtain a second reservation preemption command, sending the second reservation preemption command to a second storage apparatus via the forwarding port, the second storage apparatus performing a reservation preemption operation according to the port identifier of the target port. A related storage apparatus for realizing the data processing method is further provided. The invention is capable of guaranteeing the consistency of data between different storage arrays when a split-brain situation occurs in a host aggregate during the process of implementing online data migration in different storage arrays, and has more application scenarios since it is not reliant on a fiber channel switch.
