Abstract
A disk array apparatus has a plurality of the same type of disk array units. Each of the disk array units has a plurality of storage areas in each of which firmware for allowing the disk array unit to operate is stored. When the disk array apparatus recognizes that a first disk array unit has been disposed therein, it compares a version number of firmware stored in each storage area included in the first disk array unit with a version number of firmware stored in each storage area included in a second disk array unit that currently operates in the disk array apparatus. If these version numbers are the same, the disk array apparatus makes a storage area in which firmware executed by the first disk array unit is stored conform to a storage area in which firmware executed by the second disk array unit is stored.
