ABSTRACT:
A response of a disk device during rebuild can be sped up. A disk array control device determines whether or not there is a normal read request during rebuild. If there is a read request during rebuild, data is read by sequentially switching a plurality of disk devices in a certain block size unit lower than a block size in which each disk device reads data during normal read.
