摘要： Provided is an access right managing method for a resource of a storage system, in which a management computer stores access right definition information of the resource, and resource correspondence information including information on a management program which manages another resource related to the resource managed by the management program. In case of which receiving an updating request of an access right of the resource, the management computer updates an access right based on the updating request of the access right, selects a management program of the resource whose access right is requested to be updated based on the resource correspondence information, transmits an updating request of an access right for a relative resource to a management computer which executes the selected management program, and in case of which the access right updating request of the related resource is received, updates the access right of the relative resource.

摘要： Groups of volumes having a certain amount of commonality of data are identified within a storage system. For each group, the process defines a base volume, such as the volume containing the most commonality with the other volumes. For each volume in the group, the process extracts differential data between the base volume and each other volume, saves the differential data in a pool volume, and updates a mapping table. Commonality between volumes in the group is managed in the base volume, the pool volume, and the mapping table. Then the original volumes except the base volume and the pool volume may be deleted, and the original volumes are replaced with virtual volumes accessible through the mapping table. As a result, the amount of data in a storage system can be reduced while maintaining data integrity and accessibility.

摘要： A method for operating a storage system includes providing a primary storage device and a secondary storage device. Data from a first storage volume is copied to a second storage volume using an internal mirror operation, the first and second storage volumes being provided within the primary storage device. The data received from the first volume is copied from the second storage volume to a third storage volume using a remote copy operation, the third storage volume being provided in the secondary storage device. The second storage volume is used for the remote copying to reduce the IO impact on the first volume. The third storage volume copies the data received from the second volume to a fourth storage volume using an internal mirror operation, the fourth storage volume being provided within the secondary storage device. The secondary storage system includes a fifth storage volume that is made available to a secondary host while the data from the third storage volume is being copied to the fourth storage volume, the secondary host being associated with the secondary storage device.

摘要： A virtualization system is introduced between a host and a storage system. An apparatus, system, and method of migrating replication includes stopping or making dormant applications on a host, or checking whether the applications are stopped or dormant. The statuses of a primary volume and a secondary volume that is a replica of the primary volume are checked to determine whether they have become identical. A primary virtual volume is defined to map to the primary volume and a secondary virtual volume is defined to map to the secondary volume. Replication is defined from the primary virtual volume to the secondary virtual volume. Replication is started with a NOCOPY option, and the applications may be restarted or a message is sent indicating that the applications can be restarted. There is no actual migration of application data, and as result, the time required for migrating replication can be eliminated.

摘要： A file to be written can be partitioned into one or more partitions. Each such input partition is identified with a hash code and a group ID. Replica(s) of an input partition can be created to ensure a certain number of identical partitions. When a file is accessed, each partition that is read out can be checked for corruption. Corrupted readout partitions are then replaced with a validated replacement partition, whether the replacement partition is from a replica or from another file.

摘要翻译： 要写入的文件可以划分为一个或多个分区。 每个这样的输入分区用哈希码和组ID标识。 可以创建输入分区的副本，以确保一定数量的相同分区。 当访问文件时，可以检查每个读出的分区是否有损坏。 然后，损坏的读取分区将被替换为经过验证的替换分区，无论替换分区是来自副本还是来自另一个文件。

摘要： A system and method for automatic failure recovery in a storage system that includes replicating data stored in a first storage volume at a storage system into a second storage volume at the storage system, the first storage volume handling Input/Output (I/O) operations between the storage system and a host device. A failure is detected in the I/O operations with the first storage volume and a recovery process initiated that includes identifying a path from the host device to the second storage volume or a third storage volume to allow continuation of the I/O operations automatically. The third storage volume containing data recovered from the second storage volume.

摘要： A definition tool of the present invention declares columns which are concealed in external tables to a multi-database server. The multi-database server controls a decomposition and an execution of query messages such that the multi-database server does not perform an arithmetic using the concealed columns. The external database server encrypts the data of concealed columns in tables of query result tables. The multi-database server designates a range to be decrypted at the time of acquiring and integrating respective result tables. A client program acquires an integrated result table and decrypts the designated range. Since the data encrypted by the external database server is decrypted by and is referred to the client program, it becomes difficult for the multi-database server to refer to a content of the concealed columns.

摘要翻译： 本发明的定义工具将隐藏在外部表中的列声明到多数据库服务器。 多数据库服务器控制查询消息的分解和执行，使得多数据库服务器不使用隐藏列执行算术。 外部数据库服务器加密查询结果表的表中隐藏列的数据。 多数据库服务器在获取并集成各个结果表时指定要解密的范围。 客户程序获取一个综合结果表并解密指定范围。 由于由外部数据库服务器加密的数据被解密并被称为客户机程序，因此多数据库服务器难以引用隐藏列的内容。
