Publication number: 20150331926Abstract: The invention relates to an information processing apparatus which performs mirroring for synchronizing storage contents of a first storage unit and a second storage unit. If mirroring is valid when the information processing apparatus is started, the information processing apparatus detects a storage unit attached to itself. If a detection result indicates that no storage unit has been detected or one storage unit has been detected, the information processing apparatus displays, on a display unit, a connection acknowledgement screen for the storage unit which has not been detected. If the detection result indicates that two storage units have been detected, activation processing is executed for the information processing apparatus.Type: ApplicationFiled: July 29, 2015Publication date: November 19, 2015Inventors: Koji Shimizu, Keishi Inaba, Kohei Asano, Kiyokazu Umimura, Yuji Naya, Yuichi Konosu
