NAME

       dvhtool - Disk volume header manipulation tool

SYNOPSIS

       dvhtool --device devicename [ option ]

       dvhtool -d devicename [ option ]

DESCRIPTION

       dvhtool  is  a  utility  for  displaying  SGI disk partition and volume
       header information as well as for copying files to and from the  volume
       header.

       It  is  similar  to  the IRIX(tm) utility of the same name, however the
       options and usage are quite different.  Also, the IRIX  utility  cannot
       display partition and boot file information.

       The disk volume header includes the disk partition table and the volume
       directory.  The volume directory is an index to the files stored in the
       volume  header  part  of the disk.  These files can be anything but are
       usually standalone programs (like sash, the SGI standalone shell).  The
       space  available  for  files  is  usually  limited to one, two or a few
       megabytes, this can only be changed by repartitioning the disk with fx,
       the SGI disk formatting and partitioning tool or fdisk.

       You  must  be  root to invoke dvhtool.  The device name can be /dev/sda
       for the first disk, /dev/sdb for the second, and so on.

       dvhtool will also work on a file image of a disk volume header.

       OPTIONS -d,  --device devicename Specify the volume header device  name
       (or file image)

       --print-volume-header
              Show volume header data only

       --print-volume-directory
              Show volume table of contents

       --print-partitions
              Show partition data

       --print-all
              Equivalent to all three above options

       --vh-remove name
              Remove volhdr file name.

       --vh-to-unix name file
              Copy volhdr file name to Unix file file

       --unix-to-vh file name
              Copy Unix file file to volhdr as name

       --help Show usage information
