摘要： A storage apparatus has a plurality of storage media including each storage area in which a stripe is set extending over the storage area of the plurality of storage media. An access unit that writes a format data into the storage area, wherein when the plurality of storage media are formatted, the access unit writes an unformatted-state identifier indicating incompletion of formatting into at least a portion of storage area to be included in the stripe, or when the storage area to be included in the stripe is accessed for writing new data, the access unit reads out existing data stored in the storage area included in the stripe to be accessed. And when the unformatted-state identifier is detected from the existing data that has been read out, the access unit writes the new data or the format data to be written by formatting into the storage area.

摘要： A storage control apparatus manages a plurality of storage devices which belong to an RLU such that data is made redundant between different storage devices. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.

摘要： A storage control apparatus manages a plurality of storage devices which belong to a RAID Logical Unit (RLU) such that data is made redundant between different storage devices, where RAID stands for Redundant Arrays of Independent Disks. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.

摘要： A control apparatus, coupled to a storage medium via communication links, controls data write operations to the storage medium. A cache memory is configured to store a temporary copy of first data written in the storage medium. A processor receives second data with which the first data in the storage medium is to be updated, and determines whether the received second data coincides with the first data, based on comparison data read out of the storage medium, when no copy of the first data is found in the cache memory. When the second data is determined to coincide with the first data, the processor determines not to write the second data into the storage medium.
