      vxdisksetup, vxdiskunsetup - configure a disk for use with VERITAS
      Volume Manager

      /etc/vx/bin/vxdisksetup [-iB] disk_device_address [ attribute...]

      /etc/vx/bin/vxdiskunsetup [-C] disk_device_address...

      The vxdisksetup command configures the disk for use by VERITAS Volume
      Manager (VxVM).  vxdisksetup is called by the vxdiskadd command as
      part of initial disk configuration.  It is not typically necessary to
      call this command directly.  vxdisksetup creates a VERITAS Volume
      Manager private configuration region and public region for allocating

      The vxdiskunsetup command reverses the configuration done by
      vxdisksetup and makes the specified disks unusable by VxVM.
      vxdiskunsetup can be applied only to VxVM-initialized disks that are
      not in use within an imported disk group.

      The disk_device_address argument passed to vxdisksetup or
      vxdiskunsetup directs the command to the disk being operated upon.
      The address should be provided in the form c#t#d#, which define a
      controller number (c#), a SCSI target ID (t#), and a SCSI logical unit
      number (d#).  Each number is specified in decimal and can be multiple
      digits.  If the disks are named using the enclosure based naming
      scheme, the address usually takes the form enclosurename_diskno.	The
      name must reference a valid disk under the /dev/vx/rdmp directory.

      The vxdiskunsetup command operates by removing the public and private
      regions that were created by the last invocation of vxdisksetup on the
      specified disks.	After this operation, those disks are converted from
      the online to the online invalid state (as displayed by vxdisk list).
      The command does not operate on disks that are active members of an
      imported disk group.

      -B	Initializes the VERITAS Volume Manager private region to
		begin at block number 2144.  This block is designated as the
		private region offset for a VERITAS Volume Manager root
		disk.  Without this option, the private region is
		initialized to start at the default block number 128.

      -C	vxdiskunsetup usually does not operate on disks that appear
		to be imported by some other host (for example, a host that
		shares access to the disk).  In this case, the -C option can
		be specified to force de-configuration of the disk,
		effectively removing the host locks that were detected by

      -i	Writes a disk header to the disk, making the disk directly
		usable (as a new disk in a disk group, for example).

      You can specify attributes to affect the layout strategy used by

      CAUTION: Be very careful when using these attributes as they can
      render a disk unusable by VxVM.

      config	Sets up kernel logs or configuration databases on the disk.
		config is the converse of the noconfig attribute and is the
		default.  config is ignored unless the -i option is

      noconfig	Prevents setting up kernel logs or configuration databases
		on the disk.  The size of the default private region is set
		to 160 blocks, which is the minimum allowed private region
		size.  noconfig is ignored unless the -i option is

		Specifies the length of the private region of the disk.	 The
		default size of this area is 2048 blocks.  The maximum
		possible size of the private region is 524288 blocks.

		Indicates the sector offset of the private region on the
		disk.  The default value for the private region offset is
		block number 128 for non-boot disks and block number 2144
		for boot disks.

		Specifies the length of the public region of the disk.	This
		defaults to the size of the disk minus the private area on
		the disk.

		Sets the offset on the disk where the public region starts.
		This defaults to the end of the private region unless the
		private region is moved from the beginning of the disk, in
		which case the public region offset defaults to following
		the private region.

      To initialize a disk for regular use, enter:

	   /etc/vx/bin/vxdisksetup -i c2t1d0
