  NAME

    disktab - Disk description file

  DESCRIPTION

    The /etc/disktab file is a simple database which describes disk geometries
    and disk partition characteristics.  Entries in disktab consist of a
    number of colon (:) separated fields.  The first entry for each disk gives
    the names which are known for the disk, separated by pipe (|) characters.
    The last name given should be a long name which uniquely identifies the
    disk.

    The following list indicates the normal values stored for each disk entry:

                    Name   Type           Description
                    _________________________________________

                                  cylinder
                     nc    num    total number of cylinders
                                  on the disk
