Abstract: A related art has not taken account of the authority to manage the physical configuration of a storage system. Therefore, the configuration of a storage system cannot be safely managed. Moreover, storage systems to be used by administrators may be duplicate. The availability of an entire computer system is degraded due to stoppage of a storage system caused by scheduled maintenance or the like. Responsively to a manipulation a storage administrator performs in order to allocate or un-allocate a volume, the authority to manage the physical configuration of a storage system is given to the storage administrator or the storage administrator is deprived of the authority. Specifically, a volume allocation program installed in a management computer gives the storage administrator the authority to manage the physical configuration of a storage system, which includes a created volume, responsively to creation of the volume.

The volume management system comprises a storage having volumes served as a storage region, a managing computer, and a plurality of hosts used by users obtaining an operation authority over the volume. Two or more users can use an identical volume. Upon obtaining an operation content of one user for at least one of the volumes over which two or more users have the operation authority, the managing computer determines from an attribute of the volume and the operation authority of the two or more users over the volume whether the operation content is executable. When the operation content is not executable, the operation content is restrained.

Abstract: With respect to an administrator in a data management system, although an authority to see contents of data is not granted depending on a job of the administrator, it is necessary to acquire information of a volume in order to replicate the data on a computer in a job such as a replication of the data at the time of managing a storage system, and since the data can also be operated by the administrator who replicates the data, there is a problem from the view point of security. A volume to encrypt and decrypt is determined by a user management program 112 of a management computer 100 according to a user's job. Further, as to whether to encrypt or whether to decrypt, a command of yes/no of the encryption and decryption is given to an encryption apparatus in accordance with the authority in an application of the user so as to perform the job such as performing the data replication by the encrypted data.

Abstract: A configuration management computer and program for managing volume configuration of a computer system are provided. This program collects configuration information from a host computer, switch, and storage system, that are objects for management, and creates correspondence of usage between a replica volume and a replica configuration definition.
