Abstract
A storage apparatus includes first and second controller modules. The first controller module monitors power states of the first and second controller modules. When the monitoring results indicate that the power state of the first controller module is an ON state and the power state of the second controller module is an ON processing state in which an ON process of switching from OFF to ON is being executed, the first controller module maintains the power state of the first controller module upon detection of a power control signal for controlling the power state of the first controller module.
