摘要
A management data synchronization method and apparatus applied to a master controller, and a management data synchronization method and apparatus applied to a slave controller, and a storage device and a readable storage medium. According to the method, multicast technology is used to design progressively increasing multicast serial numbers and sequentially process multicast messages, and a slave controller determines, by means of the multicast serial numbers, whether messages are missing, and insofar as the messages are missing, actively pulls missing messages from a master controller, such that management data synchronization is realized. According to the method, insofar as the synchronization workload of the master controller is reduced, the consistency of management data in the slave controller and the master controller is ensured, and the system stability of a multi-controller storage array can be further ensured.
