Claim:
A computer system comprising: a storage system including a first volume and a second volume; a first host computer coupled to the storage system, which executes a first application program, a first access environment program, and access environment information indicating a configuration of the first access environment program; a second host computer coupled to the storage system; and a management computer coupled to the storage system and the first host computer and the second host computer, wherein the first access environment program converts an application data created by the first application program, according to the access environment information, and sends the converted application data to the first volume, wherein the storage system copies data stored in the first volume to the second volume, wherein the management computer stores the access environment information, and relationship between the second volume and the access environment information, wherein, when the management computer receives a request to access the second volume from the second host computer, the management computer identifies the access environment information based on the relationship, and sends the access environment information to the second host computer, and wherein the second host computer configures a second access environment program stored in the second host computer based on the access environment information, and wherein a second application program is stored on the second host computer, and accesses the second volume via the second access environment program configured by the access environment information.
