VOLUME MANAGEMENT METHOD IN A STORAGE APPARATUS HAVING ENCRYPTION FEATURE
First Claim
1. A management computer connected to plural host computers and plural storage apparatuses, each host computer being designed to execute an application program, and each storage apparatus connected to the host computers having plural logical volumes,the management computer comprising:
- memory for storing first association information for associating each application program with application security level information indicating a security level required by the application program, and second association information for associating each logical volume with logical volume security level information indicating a security level in the logical volume;
an interface for receiving a logical volume allocation request specifying an application program; and
a processor for specifying, based on the first association information, application security level information that indicates the security level required by the application program specified by the logical volume allocation request, and selecting, based on the second association information, from the plural logical volumes, a logical volume that satisfies the security level indicated by the specified application security level information.

Abstract
The invention provides a computer system including a storage apparatus having an encryption feature, a management computer for running a management program for managing the storage apparatus, and an application host computer, wherein when allocating a logical volume or creating a copy pair, the management program selects, from the storage apparatus, a logical volume that satisfies a security level required by an application program that uses the logical volume to allocate the logical volume or create a copy pair.
