Abstract
In a storage apparatus a control section writes, at the time of updating at least a part of first data stored in a first storage area by at least a part of second data, the second data to a second storage area other than the first storage area. In addition, the control section determines whether or not a write error occurs. When the write error does not occur, the control section combines the first data and the second data.
Claims15
A storage apparatus comprising:
- a controller which writes, at the time of updating at least a part of first data stored in a first storage area by at least a part of second data, the second data to a second storage area other than the first storage area, which determines whether or not a write error occurs, and which combines, at the time of the write error not occurring, the first data and the second data.
A control apparatus comprising:
- a controller which writes, at the time of updating at least a part of first data stored in a first storage area by at least a part of second data, the second data to a second storage area other than the first storage area, which determines whether or not a write error occurs, which combines, at the time of the write error not occurring, the first data and the second data, and which updates data that is stored in a storage device and that corresponds to the first data and the second data by data obtained by the combination.
A control method for controlling a storage apparatus, the control method comprising:
- writing, at the time of updating at least a part of first data stored in a first storage area by at least a part of second data, the second data to a second storage area other than the first storage area, and determining whether or not a write error occurs;
- and
- combining, at the time of the write error not occurring, the first data and the second data.
