ctape1    For rewinding, non retensioning
      ntape1    For non rewinding, non retensioning
      rtape1    For rewinding, retensioning
     nrtape1    For non rewinding, retensioning
      utape1    For unloading the tape after the operation.

Tape devices can also have c#b#t#l#.

   The c, b, t, and l stand for:
      c# is the controller number (like c0 or c1 for each HBA card or IDE).
      b# is the bus number of the HBA.  This is usually 0, as in b0.
      t# is the scsi id (or scsi target id) of the device you are naming.
      l# is the lun number (also usually 0 as in d0).
    where on a disk drive
      d# is the lun number (also usually 0 as in d0).

    Use a device like ctape2 if you have a second drive.

Substitute a 2 if you are using the second tape drive. Usually we find ourselves using /dev/rmt/ctape1 for common cpio and tar tasks.
