C is the controller, referencing the controller on the system to which the disk drive is connected. This number will be the same for all disks connected to that controller. T is the target number. On a SCSI bus, for example, each disk has its unique target number. D is the hardware device unit number. This is only important for disk/tape products that have two or more devices with a shared controller. For products not on a shared controller, the device unit number will always be 0. For products on shared controller the numbers reference the internal number of the device units. S is the section number of the disk. By default, the insf command will not create device files for all sections of a disk. If you don't want to use the logical volume manager you must manually create the device files for the different disk sections with mksf.
