Abstract
When a controller receives a new command from a main controller during overwrite-deletion processing for a specific storage apparatus, the received command is stored at least until completion of the overwrite-deletion processing when the received command is a command to the specific storage apparatus. Alternatively, progression of overwrite-deletion process is stored and priority processing of the received command is executed. On the other hand, when the received command is not a command to the specific storage apparatus, processing for the command is executed.
