摘要： A method for copying data from a source logical device to a destination logical device. In response to a copy command from a requesting host application identifying the source and destination logical devices, an environment is established. Thereafter a calling system receives an immediate response that the copy operation is complete even though no data has been copied. Application programs may access storage locations in either the source or the destination logical device during the copy phase. A copy program transfers the date on a track-by-track basis to the destination logical device. Procedures assure that any data access to a particular track in either the source or destination logical device by any application prior to the transfer of that track is accommodated to maintain data integrity.

摘要： A method and apparatus for manipulating data in a storage device that is coupled to a host computer. Manipulations that can be performed by the storage device include moving non-contiguous blocks of data between the host computer and the storage device in a single operation. Other manipulations can be performed directly by the storage device without passing data to or from the host computer and include copying data from one logical object that is defined on the host computer to another, initializing, backing-up, transforming, or securely deleting a logical object that is defined by the host computer with a single command. In one embodiment, an application programming interface is provided that allows a relationship between logical objects on a host computer and storage locations on a storage device to be communicated between the host computer and the storage device. By providing the storage device with knowledge of the relationship between a logical object and the storage locations corresponding to that logical object, data corresponding to the logical object can be manipulated directly by the storage device, rather than by the host computer. In another embodiment, a graphical visualization routine is provided that displays the global mapping of a logical object to a set of physical blocks on the storage device for each layer of mapping below the logical object.

摘要： Described are techniques used in defining and maintaining group data used by multiple host systems. Group data is stored in a distributed fashion on one or more data storage systems. If a device of a data storage system belongs to a group, group data for that group is stored on that data storage system. Group data changes made by one host are communicated to the other hosts by accessing a common data area on each data storage system using a daemon executing on each host. Remotely mirrored groups may be defined on a remote data storage system. A remote mirror of a group includes group data modified in accordance with a point of view of the remote data storage system and a remote host.

摘要： Described are techniques for simulation of a data storage system configuration. The simulation state reflects the data storage system configuration in accordance with an application programming interface (API) model. API calls result in reading existing data storage system configuration data and/or modifying the configuration data by execution of one or more low level calls. A daemon may operate in a simulation mode in which the low level calls are simulated rather than resulting in communications with a data storage system when operating in a non-simulation mode. A low level cache is used to store simulated values returned from the data storage system microcode. A high level cache is used to store API call return data. A seed file is used to initialize the simulation state.
