Adding SCSI tape drives

This is to save someone else the pain, as there's a huge
lack of info.

I've make the device accessible by members of the "disk" group.
This isn't necessary.

Operating System: Red Hat Linux 6.0

Establish "tape" pseudo-device:
  su
  cd /dev
  ./MAKEDEV st0
  ./MAKEDEV nst0
  chgrp disk st0
  chgrp disk nst0
  newgrp disk
     ln -s st0 tape
     ln -s nst0 ntape
     exit
  exit

Set up modules:
  su
  vi /etc/conf.modules
    # Controller: AHA-2940 (PCI)
    #   SCSI ID: 7
    #   Connector: HP-CEN
    alias scsi_hostadapter aic7xxx
    # Tape: HP SureStore 6000 (model C1529-62702)
    #   SCSI ID: 5
    #   Connector: Centronics
    #   Termination: external passive Centronics
    # it is the zeroth (and only) device detected on the SCSI
    # bus, so has minor number 0 for /dev/st0 and 128 for
    # /dev/nst0.
    alias char-major-9-0 st
    alias char-major-9-128 st
  depmod -a
  exit

Test:
  su
    mt rewind
    dmesg
    exit

The successful output from dmesg is:
