Abstract

A computer system wherein a first access environment program converts an application data created by the first application program, according to access environment information, and sends the converted application data to a first volume, wherein a 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 and a second application program stored the second host computer, accesses to the second volume via the second access environment program configured by the access environment information.

Claims

1. 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 and a second application program stored the second host computer, accesses to the second volume via the second access environment program configured by the access environment information.

2. A computer system according to claim 1,

wherein the second host computer installs the second access environment program before receiving the request to access the second volume from the second host computer.

3. A computer system according to claim 1,

wherein the second host computer installs the second access environment program according to reception of the request to access the second volume from the second host computer.

4. A data managing method in a computer system including a first host computer, a second host computer, a storage system, and a management computer, comprising:

by a storage system, configuring a first volume and a second volume;

by the first host computer, installing a first application program and a first access environment program;

by the first host computer, storing access environment information indicating a configuration of the first access environment program;

by the first application program, generating an application data;

by the first access environment program, converting the application data according to the access environment information, and sending the converted application data to the first volume;

by the storage system, copying data stored in the first volume to the second volume;

by the management computer, storing the access environment information, and relationship between the second volume and the access environment information;

when the management computer receives a request to access the second volume from the second host computer, by the management computer, identifying the access environment information based on the relationship, and sends the access environment information to the second host computer; and

by the second host computer, configuring an second access environment program installed to the second host computer, based on the access environment information; and

by a second application program installed to the second host computer, accesses to the second volume via the second access environment program configured by the access environment information.

5. A data managing method according to claim 4,

wherein the second host computer installs the second access environment program before receiving the request to access the second volume from the second host computer.

6. A data managing method according to claim 4,

wherein the second host computer installs the second access environment program according to reception of the request to access the second volume from the second host computer.
