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

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
