摘要
PURPOSE: A method for operating/managing a distributed/shared RAID(Redundant Array of Inexpensive Disks) system based on a SAN(Storage Area Network) is provided to reduce a load of a web server and a diagnosis/management program, and enhance the security reliability by managing/controlling a system through a server based on the web. CONSTITUTION: If a management object is downloaded by using the node information obtained through a heartbeat message, a current state of the server is judged(S402). If the current state of the server is in-service, a download process is terminated. In case that the download of the management object is needed, the state of the server is changed to going-in-service, and the state of all nodes of the in-service is changed to a standby state by broadcasting a standby message to all servers and controllers(S406). Thus, the discordance during the download of the management object is removed by making the standby nodes process only a restricted message.
