摘要： A system creates a configuration definition table to be used for accessing a physical disk according to a host I/O request, to decrease a memory size of the configuration definition table even if common firmware is used for models with different scales. For this, a model correspondence table to show the definition of each model is provided in a configuration setup processing module, the maximum values of this model are recorded in a memory based on this content, and a memory area for each item is secured. And the actual content of the configuration definition is developed on the secured memory. Therefore even for a diversity of models, the memory size of the configuration definition table can be decreased to a size matching the model, with common firmware regardless the model.

摘要： In a storage system, a disk device performs recovery and transfers read data to a control device, and the control device judges the validity of the recovery to prevent a transfer of erroneous data. A control device read-accesses a disk device, and the disk device returns read data and a recovered read error response. A control device, at the time of an initial recovered read error, performs a retry of a similar command, and if an error does not occur for read commands including the retry read command, judges the data to be valid. Uncertain data (suspect data) upon occurrence of a recovered read error is restored through disk retry, and accurate read data can be transferred to the host.

摘要： A RAID system access a physical disk and perform Rebuild/Copy back processing according to a host I/O request, so as to implement high-speed Rebuild/Copy back processing without interfering with the processing of a normal I/O. When one disk device fails, out of a plurality of disk devices constituting a RAID configuration, the controller performs Rebuild/Copy back processing to reconstruct the RAID. In Rebuild/Copy back, the controller reads the data from one disk and writes the data to another disk, so the presence of a normal I/O is judged, and when a normal I/O is absent, read and write of these different disk drives are executed simultaneously. By this, the Rebuild/Copy back time can be decreased.

摘要： A code conversion apparatus, a disk drive, a code buffer, and an encryption buffer are included in a storage. The code buffer stores therein first encrypted data present in the disk drive, and the encryption buffer stores therein first unencrypted data present in the disk drive. An encrypting unit encrypts the first unencrypted data present in the encryption buffer to predetermined encrypted data, and a decrypting unit decrypts the first encrypted data present in the code buffer to second unencrypted data. Moreover, a re-encrypting unit decrypts the first encrypted data present in the code buffer to third unencrypted data and encrypts the third unencrypted data to second encrypted data different from the first encrypted data.

摘要： The present invention has been made to obtain a magnetic disk apparatus and the like capable of using a patrol region in the magnetic disk to detect a location in need of maintenance in hardware equipment around the magnetic disk in a separate manner from the disk itself and thereby avoiding useless replacement and operating the magnetic disk apparatus at low cost. In a preventive maintenance detection for a magnetic disk apparatus having a patrol function that uses a patrol region in the magnetic disk to determine the presence/absence of the need of preventive maintenance, a data pattern for detecting crosstalk in hardware equipment around the disk is generated, a write command or read command corresponding to the generated data pattern is executed, and the crosstalk is determined/detected based on the command execution result.
