摘要： The device controller (a) executes a data I/O process with respect to a physical storage area in accordance with an I/O command, and (b) sends to the storage controller an I/O command-related response comprising status information subsequent to being changed in accordance with the I/O process. The storage controller (A) receives the response from the target physical storage device, and (B) based on the status information included in the response received in (A), makes a determination as to whether or not to execute internal processing, and in a case where the result of the determination is to execute internal processing, sends to the target physical storage device an internal processing execution command instructing the execution of internal processing. The device controller in the target physical storage device (c), upon receiving the internal processing execution command, executes internal processing in accordance with the internal processing execution command.

摘要： A storage system includes a plurality of disk apparatuses configuring a plurality of RAID groups, a spare disk apparatus, and a controller. The controller is adapted to copy data stored in a disk apparatus, whose error count exceeds a first threshold, to the spare disk apparatus. If an error count of a disk apparatus included in a RAID group exceeds a second threshold which is lower than the first threshold, the controller is adapted to check error counts of other disk apparatuses included in the same RAID group. If any of the error counts of the other disk apparatuses included in the same RAID group exceeds the second threshold, the controller is adapted to change the first value of the first disk apparatus and the other disk apparatuses included in the same RAID group.

摘要： The invention is intended to reduce disk access during data transfer from a disk in which occurrence of failure is anticipated to a spare disk as much as possible so that occurrence of double-failure is prevented in advance. When occurrence of failure in a disk which configures a RAID group, contents stored in the disk is copied to the spared disk. Simultaneously, another RAID group is paired with the above described RAID group and a secondary volume is provided therein. A write request is directed to the secondary volume. A differential bitmap controls a update data. Data which is not updated is read out from the primary volume, and data which is already updated is read from the secondary volume. When data transfer is completed, contents stored in the secondary volume are copied to the primary volume.
