Location of SCSI bus connectors
The integrated SCSI controller is factory–specified as Controller 0;
system software knows the controller by its device name ncsc(0).
The optional SCSI buses are factory–specified as Controller 1 and
Controller 2 (first expansion board) and Controller 3 and
Controller 4 (second expansion board). Figure 3–1 shows the default
device names for each SCSI controller.
Of course, if your system does not include the optional SCSI I/O
expansion boards, the slots do not contain SCSI bus connectors.
Each SCSI bus in your system supports up to seven devices housed
internally, independently, or within a storage subsystem.
