Check the SCSI ID Settings
Each device in your system must have its
own unique SCSI ID setting. If your DEC
3000 system has a factory-installed drive, it
is set to SCSI ID 3.
You can check the SCSI ID settings on your
drives by referring to the DEC 3000 Model
400/400S AXP Options Guide. The RZ23L
and RZ24 SCSI ID settings (not covered in
the guide) are shown here.
