摘要： A method, system and program are disclosed for efficiently processing host data which comprises encrypted and non-encrypted data and is to be written to a storage medium. The encrypted data is written to the storage medium in encrypted form. The non-encrypted data is encrypted by a storage device using a well known encryption key and written to the storage medium. In this way, the data that is processed by the storage device to and from the storage medium can always be processed through a single encryption engine.

摘要： Provided are a method, system, and article of manufacture in which a non-reversible signature of a symmetric cryptographic key is computed, wherein the symmetric cryptographic key is used to symmetrically encrypt data at rest in a storage device. The non-reversible signature is stored in association with the symmetrically encrypted data at rest in the storage device. The non-reversible signature is used to determine validity of a cryptographic key provided by a host for accessing the symmetrically encrypted data at rest in the storage device.

摘要： A system and computer program product are provided for utilizing target of opportunity to perform at least one special operation while a removable storage medium is mounted within a data storage drive for another purpose. The system comprises a tape library and a tape drive coupled to the tape library. The tape library receives a command to mount a tape cartridge in the tape drive. If it is determined by the tape library that at least one special operation may be performed, then tape library has recognized that a target of opportunity exists. In response to determining that at least one special operation may be performed, the tape library sends a first notification that the tape drive is to remain in a not ready state. The tape library mounts the tape cartridge in the tape drive after determining that at least one special operation may be performed. In response to the tape drive performing the at least one special operation, the tape library sends a second notification that the tape drive is in a ready state or an error state.

摘要： Backspacing over data to overwrite the data as recorded on magnetic tape is provided logically, rather than by causing a magnetic tape to drive to backhitch. The data is written to the magnetic tape as it was before it was logically changed in order to insure that the data is preserved on tape. Recovery of the data is from a succeeding data set which logically invalidates the original data by a superseding identifier. Control logic arranges data transactions for writing to magnetic tape as data sets; and, in response to backspace and overwrite commands, or when transactions are accumulated into a succeeding data set, rewrites the original transaction adjusted in accordance with the commands as a superseding data set downstream from the original transaction, logically invalidating the original transaction by setting a superseding identifier in the superseding data set(s).
摘要翻译：逻辑上提供了对数据进行覆盖以覆盖磁带上记录的数据，而不是通过使磁带驱动到后退。数据被写入磁带，因为它是在逻辑上改变之前，以确保数据保存在磁带上。来自后续数据集的数据的恢复，其通过替代标识符逻辑地使原始数据无效。控制逻辑将数据交易写入磁带作为数据集; 并且响应于退格和重写命令，或者当事务被累积到后续数据集中时，重写根据命令调整的原始事务作为来自原始事务下游的替代数据集，通过设置原始事务来逻辑地使原始事务无效在取代的数据集中替代标识符。
