摘要： A copy export application implemented in a computational device receives a request to perform a copy export operation of data and metadata to a selected tape in a tape library coupled to the computational device. The copy export application copies the data from the computational device to the selected tape. The copy export application determines a medium error on the selected tape while copying the metadata from the computational device to the selected tape, subsequent to completion of the copying of the data from the computational device to the selected tape. The copy export application sends a request to a tape control application to replace the selected tape by a new tape and copy the data from the selected tape to the new tape. The copy export application copies the metadata to the new tape.

摘要： A hybrid data storage system is one which has data storage clusters of different types. In a hybrid data storage system, at least one first data storage cluster is configured to store data and has high data storage capacity; and at least one second data storage cluster is configured to store data and has lower data storage capacity than the first cluster. The data is initially replicated and stored by at least one first and at least one second data storage cluster. The method identifies a portion of the stored initially replicated data of at least one second data storage cluster as “pinned”; continues to store the pinned initially replicated data; and selectively removes non-pinned initially replicated data from the second data storage cluster(s) to account for the capacity difference.

摘要： Provided are a method, system, and program for performing a data transfer operation with respect to a source and target storage devices in a network, wherein storage devices in the network are assigned temporary network addresses. Device information is maintained and includes for each identified device a fixed address that does not change and a temporary network address. A data transfer request is received to transfer data between a source and target devices. The network is queried to determine changes to the temporary network addresses of the storage devices in response to receiving the data transfer request and the device information is updated to include any changed determined temporary network addresses for the storage devices. A data transfer command is constructed to transfer data between the source and target storage devices, wherein the data transfer command includes the temporary network addresses of the source and target devices in the device information.

摘要： An apparatus, system, and method are disclosed for data access management on a storage device connected to a storage area network. A client includes network connections to a first and second network, where the second network comprises a storage area network (SAN). The client also includes a storage management client and a storage agent. The storage agent is configured to minimize the amount of metadata processing that occurs on the client by sending the metadata or a copy thereof to a storage server to be stored in a centralized metadata database. The storage server also includes a storage manager that is configured to manage data access by the storage agent to the requested storage device.
