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

NAME

       vxvmboot - prepare Veritas Volume Manager volume as a root, boot, primary swap or dump volume

SYNOPSIS

       /sbin/vxvmboot [-b|-d|-r|-s] [-v] -o offset -l length rawpath

       /sbin/vxvmboot -v rawpath

       /sbin/vxvmboot -c

DESCRIPTION

       The  vxvmboot  command updates information in the LABEL file for the lif disk specified by the pathname of its character (raw) device node,
       rawpath.  The volume at the specified offset and length becomes the boot, root, primary swap or dump volume when the system is next booted.

       This command is normally invoked by the vxbootsetup utility.

OPTIONS

       -b	 Specifies the volume type as a boot volume with name standvol.

       -c	 Is used to update the /stand/rootconf file with the offset and length of the rootvol. The usage is slightly different when the -c
		 argument  is  used.  The rawpath argument is not used with this invocation. Instead the path of the boot device is extracted from
		 the /stand/bootconf file.  Also, the -o and -l arguments are not used to specify the offset and length.  Instead, the offset  and
		 length of the rootvol are obtained from the LIF LABEL file on the boot device.

		 The  -c  option would normally be used in the sbin/ioinitrc script to update the /stand/rootconf file, when the boot disk is VxVM
		 rootable.

       -d	 Specifies the volume type as a dump volume with name dumpvol.

		 If a dumpvol volume exists on the specified disk, the extent information from this volume is used. If no such volume exists,  the
		 extent information of the swap volume is used instead, and swapvol performs the dual role of swap device and dump device.

       -l length Specifies the length of the volume in units of 1024-byte blocks.

       -o offset Specifies the start of the volume as the number of 1024-byte blocks from the beginning of the disk.

       -r	 Specifies the volume type as a root volume with name rootvol.

       -s	 Specifies the volume type as a swap volume with name swapvol.

       -v	 When  used with one of the options -b, -d, -r or -s, displays the contents of the updated LABEL file.	Otherwise, this option may
		 be used to display the contents of the LABEL file on the specified lif disk.

	      Note: The -b, -c, -d, -r and -s options are mutually exclusive.  If more than one of these options is specified, the  vxvmboot  com-
	      mand exits without performing any operation.

ARGUMENTS

       rawpath	 Specifies the pathname of the character (raw) device node for the lif disk.
