dvhtool - Disk volume header manipulation tool
dvhtool --device devicename [ option ]
dvhtool -d devicename [ option ]
dvhtool is a utility for displaying SGI disk partition and volume
header information as well as for copying files to and from the volume
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)
