Data processing system having internally installed SCSI devices

摘要

A data processing apparatus 10 has two or more internal SCSI devices 54, including a SCSI controller 19, and can also accommodate external SCSI devices 57M, 57N via a port connector. The apparatus 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, by directly writing ID numbers 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 a SCSI hard disk drive that is internally positioned can be read so that the internal SCSI hard disk drive can be designated as a hibernation target to which a hibernation file is saved if the system enters into a hibernation mode because the remaining capacity of a battery falls.
