Abstract: 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.

Abstract: PURPOSE: A distributed/shared RAID(Redundant Array of Inexpensive Disks) system having a function for recovering an error of a multi-RAID controller and an error recovery method thereof are provided to make the RAID controller having the mirror data continuously perform the function of the RAID controller occurring the error by mirroring the write cache data to the rear RAID controller. CONSTITUTION: All RAID controllers(101-104) are capable of communicating with each other through the network such as the Ethernet, an optical channel switch, and the SCI(Scalable Coherence Interface). Forming the RAID controllers in a logical circular linked list, each RAID controller prevents the data loss when the error is generated by mirroring the write cache data of the RAID controller of a front side in the list to a mirroring cache of the RAID controller of a rear side. Thus, the operation of the RAID controller is continuously performed by making a role of the RAID controller generating the error succeeded to the RAID controller having the mirroring cache for the RAID controller generating the error.

Abstract translation: 目的：提供具有恢复多RAID控制器的错误的功能的分散/共享的RAID（廉价磁盘冗余阵列）系统及其错误恢复方法，以使具有镜像数据的RAID控制器连续地执行 RAID控制器通过将写缓存数据镜像到后RAID控制器来发生错误。 规定：所有RAID控制器（101-104）都能够通过网络进行通信，如以太网，光通道交换机和SCI（可伸缩相干接口）。 通过将RAID控制器组合成逻辑循环链表，每个RAID控制器通过将列表前端的RAID控制器的写入高速缓存数据镜像到RAID控制器的镜像缓存来防止错误发生时的数据丢失 后侧。 因此，RAID控制器的操作通过使RAID控制器产生错误成功的RAID控制器的角色来连续执行，该RAID控制器具有用于RAID控制器的镜像缓存器生成错误。
