Physical Device Names

The physical device name is assigned by the system firmware. This name is expressed in the form of a path name. The path name describes the location of the device in relation to the CPU. For SCSI devices the target ID is part of this address name.

After the firmware assigns the physical device names, special files are copied to the /devices directory that reflect the physical device names. This occurs when the system is booted with the reconfiguration option (boot -r or when /reconfigure file exists and the system is booted).
