Abstract: Management of a largescale SAN requires a robust configuration management system, and a strong monitoring capacity for centralized management of the resources is necessary. Storage resource management applications are one category, and they manage and monitor the physical and logical level of the storage resources. CLI, command line interface, which is used to controller commands and configure commands, is a user state executable file, using the command tree structure algorithm, with convenient operation, high efficiency, speed, safety and other properties. The paper gives its design and implementation.
