In practice the modprobe and rmmod commands (and "autoclean") will enforce the correct ordering of loading and unloading modules in the SCSI subsystem. -The individual upper and lower level drivers can be loaded in any order +The individual upper and lower level drivers can be loaded in any order once the scsi core is present in the kernel (either compiled in or loaded as a module).

You can for example load the tape driver to use the tape drive, and then unload it once you have no further need for the driver (and release the associated memory). The lower level drivers are the ones that support the individual cards that are supported for the hardware platform that you are running under. Those individual cards are often called Host Bus Adapters (HBAs). For example the -aic7xxx.o driver is used to control all recent SCSI controller cards from -Adaptec.
