Host SCSI ID All SCSI devices on one SCSI bus, including the SCSI controller, must
be set to separate SCSI addresses.
The SCSI controller is normally set to ID 7.
You do not normally need to change the SCSI address, not even if you
install several SCSI controllers. In this case each SCSI controller may
be assigned address 7, because each is connected to it's own SCSI
bus.
SCSI Bus Defines the scan order of the IDs on the SCSI bus.
