 NAME
      pvmove - move allocated physical extents from one LVM physical volume
      to other physical volumes

 SYNOPSIS
      /usr/sbin/pvmove [-A autobackup] [-n lv_path] source_pv_path
	   [dest_pv_path ... | dest_pvg_name ...]

    Remarks
      pvmove cannot be performed if the volume group is activated in shared
      mode.

 DESCRIPTION
      The pvmove command moves allocated physical extents and the data they
      contain from a source physical volume, source_pv_path, to one or more
      other physical volumes in the same volume group.

      If a destination physical volume or physical volume group is not
      specified, all physical volumes in the volume group are available as
      destination volumes for the transfer.  pvmove selects the proper
      physical volumes to be used in order to preserve the allocation
      policies of the logical volume involved.

      To limit the transfer to specific physical volumes, specify the name
      of each physical volume directly with a dest_pv_path argument.
      Optionally, if physical volume groups are defined for the volume
      group, specify the physical volumes indirectly with one or more
      dest_pvg_name arguments.

      source_pv_path must not appear as a dest_pv_path.

      If source_pv_path is a member of a dest_pv_path, it is automatically
      excluded from being a destination physical volume.

      pvmove succeeds only if there is enough space on the destination
      physical volumes to hold all the allocated extents of the source
      physical volume.

      If you have installed HP MirrorDisk/UX on your system and
      source_pv_path is an "active spare" physical volume within a mirrored
      logical volume, once all of the data has been moved to dest_pv_path,
      the source_pv_path physical volume will be returned to a "stand-by"
      spare physical volume. This is how to "unspare" data once the original
      failed physical volume has been repaired and is available to receive
      data.

    Options
      pvmove recognizes the following options:

	   dest_pv_path	       The block device path name of a physical
			       volume.	It cannot be the source physical

			       volume.	It must be in the same volume group
			       as source_pv_path.

	   dest_pvg_name       The name of a physical volume group.  It must
			       be in the same volume group as
			       source_pv_path.

	   source_pv_path      The block device path name of a physical
			       volume.

	   -A autobackup       Set automatic backup for this invocation of
			       this command.  autobackup can have one of the
			       following values:

				    y	 Automatically back up configuration
					 changes made to the physical
					 volume.  This is the default.

					 After this command executes, the
					 vgcfgbackup command (see
					 vgcfgbackup(1M)) is executed for
					 the volume group to which the
					 physical volume belongs.

				    n	 Do not back up configuration
					 changes this time.

	   -n lv_path	       Move only the physical extents allocated to
			       the logical volume specified by lv_path that
			       are located on the source physical volume
			       specified by source_pv_path.

 EXTERNAL INFLUENCES
    Environment Variables
      LANG determines the language in which messages are displayed.

      If LANG is not specified or is null, it defaults to "C" (see lang(5)).

      If any internationalization variable contains an invalid setting, all
      internationalization variables default to "C" (see environ(5)).

 EXAMPLES
      Move physical extents from /dev/dsk/c1t0d0 to /dev/dsk/c2t0d0 and
      /dev/dsk/c3t0d0:

	   pvmove /dev/dsk/c1t0d0 /dev/dsk/c2t0d0 /dev/dsk/c3t0d0

      If physical volumes /dev/dsk/c2t0d0 and /dev/dsk/c3t0d0 are the only
      ones that belong to physical volume group PVG0, the same result can be
      achieved with the following command:

	   pvmove /dev/dsk/c1t0d0 PVG0

      Move only the physical extents for logical volume /dev/vg01/lvol2 that
      are currently on /dev/dsk/c1t0d0 to /dev/dsk/c2t0d0:

	   pvmove -n /dev/vg01/lvol2 /dev/dsk/c1t0d0 /dev/dsk/c2t0d0
