Patent attributes
An electronic apparatus includes first and second processors which execute first and second operating systems, first disk controller which accesses a disk storage device in response to a disk access request from the first processor, a second disk controller which accesses the disk storage device in response to a disk access request from the second processor, a switch device to connect one of the first and second disk controllers to the disk storage device, and a unit for switching an access path, which is used when the first processor accesses the disk storage device, between a first access pass in which the first processor executes access to the disk storage device via the second processor, and a second access pass in which the first processor executes access to the disk storage device without intervention of the second processor.
