.SH DESCRIPTION
|
|
.I 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
|
|
.IR 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
|
|
.IR fx ,
|
|
the SGI disk formatting and partitioning tool or
|
|
.IR fdisk .
|
|
|
|
You must be root to invoke
|
|
.IR dvhtool .
|
|
The device name can be
|
|
.I /dev/sda
|
|
for the first disk,
|
|
.I /dev/sdb
|
|
for the second, and so on.
|
|
|
|
.I dvhtool
|
|
will also work on a file image of a disk volume header.
