       NAME
             prtvtoc - disk information display utility

       SYNOPSIS
             prtvtoc [-aep] [-f vtoc-file] raw-device

       DESCRIPTION
             The default and primary function of prtvtoc is to display the
             contents of the VTOC (Volume Table Of Contents).  The
             information displayed for each valid slice includes slice
             number, slice tag, slice flag/permissions, slice start sector,
             slice size (in sectors).

          Options
             -a    Print the alternates tables (bad tracks and bad
                   sectors).

             -e    Creates or add information to the /etc/partitions file.
                   Dependence on this feature is not suggested since it
                   will not be supported in a future release.

             -p    Print the information contained in the pdinfo structure.

             -f vtoc-file
                   Write the current contents of the VTOC into the vtoc-
                   file in a condensed format.  The format of the file is
                   slice number, slice tag value, slice flag value, slice
                   start sector, slice size (in sectors).  The purpose of
                   this file is to be input for the edvtoc command.

             raw-device
                   The character special device for the disk drive to be
                   accessed.  It must be the slice 0 device to represent
                   the entire device (for example, /dev/rdsk/0s0 or
                   /dev/rdsk/c0b0t0d0s0).

          Files
             /dev/rdsk/cCbBtTdDs0

       USAGE
             When editing the VTOC, the following entries are the valid
             slice tags and slice permission flags.

            The start and size value are in absolute sector numbers where
            the first sector on the drive is 0 (which is reserved for the
            partition table).  Slices should start and end on a cylinder
            boundary if possible.  The head, cylinder and sectors/track
            information provided by prtvtoc -p will assist in the
            calculations.  Slices should not overlap (slice 0 is the
            exception, it describes the entire UNIX partition).
