PROBLEM TO BE SOLVED: To provide a storage configuration recovery method which changes the storage configuration so that a virtualization apparatus is not interposed and operation can be resumed promptly when a failure occurs in the virtualization apparatus in a SAN environment in which the virtualization apparatus is not duplicated. SOLUTION: When a failure occurs in a virtualization apparatus in a storage network environment in which the virtualization apparatus 600 is operated, a storage management server 100 determines volume position information, cache configuration information and pair configuration information which are configuration information of the virtualization apparatus 600 and an external storage 700 comprehensively; decides candidates of a volume to be recovered and candidates of methods to recover data in the volume; configures a physical volume and pairs; restores the data; and changes an access path to the recovered physical primary volume. Consequently, the system configuration can be changed so that the virtualization apparatus 600 is not interposed in a short time and continuous operation can be attained. COPYRIGHT: (C)2009,JPO&INPIT
