It is an object to use a storage region in an efficient manner and maintain a performance of a storage system. A volume group GRincludes reference volumes, andand source volumes, andthat derive from the reference volumes. Each of the volumes stores only the difference data from a volume that is a parent thereof. A volume that is a cause of a problem is moved or copied from a pool of the momentto other pool. A configuration of a volume group is modified.

Storage system and performance management method of storage system

A computer system is provided that is capable of reducing an administrator's operational errors by connecting a new server to a SAN and automating a SAN boot setting, and capable of lightening the administrator's task of checking for a wrong connection by detecting a wrong connection made when a new server is connected to an SNW connection device. Once a new server connected to a PnP SAN starts with a boot program obtained from a boot management server, the new server transmits configuration information on the new server to a resource management server. In response to a request from the resource management server, a storage device refers to PnP SAN information to transmit SAN information on a storage network connection device to which the new server is connected. The resource management server determines to add the new server to a resource group on the basis of the SAN information and requirement information. The resource management server sets the storage device and the new server for SAN-booting the new server.
