ABSTRACT:
Disclosed is a data processing apparatus that has two or more internal SCSI devices, to include a SCSI controller, that can also accommodate eternal SCSI devices via a port connector and that can manage the ID numbers (identification numbers) of the internal SCSI devices separately from all the other SCSI devices without requiring any action by a user; and a method for controlling such a data processing apparatus. According to the present invention, ID numbers can be written into internal SCSI devices. ID numbers that do not collide with the ID numbers of the externally connected SCSI devices are assigned to the respective internal SCSI devices. The system can automatically write the ID numbers during the booting process or when the system configuration is physically changed. Even when there are SCSI hard disk drives installed both inside and outside the system, the ID numbers of the SCSI hard disk drives that are internally positioned can be read so that the internal SCSI hard disk drives can be designated. When a system enters into a hibernation mode because the remaining capacity of a battery falls low, an internal SCSI hard disk can be designated as a hibernation target to which a hibernation file is saved.
