摘要： A virtualization system, upon judging that a write operation from a higher-level device is an operation to write in the format of the virtual volume, even when the write position of the write operation is in a virtual area different from a virtual area to which an allocated actual area has been allocated, if there is an unused area in the allocated actual area, writes management information to the unused area according to the write operation, and if there is no unused area in the allocated actual area, newly allocates an unallocated actual area, and writes management information to the newly allocated actual area according to the write operation.

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： A storage controller of the present invention can input and output data even when the track size, which is the host management unit, is not consistent with the block size of the storage device. A boundary correction unit adds gap data corresponding to a gap size to data in a buffer memory so that the boundary of the track and boundary of the block inside the storage device match. A guarantee code is added to each logical block received from the host, and these guarantee code-appended blocks are stored in a cache memory. By providing a gap in the storage device every 116 extended logical blocks, the start position of the lead block of a track matches up with the start position of the logical blocks of the storage device.

摘要： Data recorded in a disk of a hard disk unit is copied to another hard disk unit. A proxy mode, for making the other hard disk unit which has been copied with the data to perform an I/O process to the hard disk unit in place thereof, is performed. Meanwhile, the firmware of the original hard disk unit is updated, and contents of the disk is set up to a latest updated state. Then, the operation in the proxy mode is stopped, and the operation is switched to an operation in a normal mode where the I/O process is directly performed to the original hard disk unit.

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.
