NAME
  lvextend - Increases the number of physical extents allocated to a logical
  volume

SYNOPSIS
  /usr/sbin/lvextend -l LogicalExtentsNumber | -m MirrorCopies
       LogicalVolumePath [PhysicalVolumePath ...]

DESCRIPTION
				     Note

       This command is no longer supported on Digital UNIX systems.
       Features formerly provided by the Logical Volume Manager (LVM)
       are now provided by the Logical Storage Manager (LSM).  Existing
       LVM volumes must be migrated to LSM, using an encapsulation
       process. For information about moving LVM volumes to LSM, see the
       vollvmencap(8) reference page and the manual Logical Storage
       Manager.


  The lvextend command changes either the number of logical extents allocated
  to a logical volume specified with the LogicalVolumePath parameter or the
  number of physical extents allocated to each logical extent in the logical
  volume. The change is determined according to which command flags you use.

FLAGS
  -l LogicalExtentsNumber
	    Increases the number of logical extents allocated to the
	    LogicalVolumePath.	LogicalExtentsNumber must be greater than the
	    number of logical extents previously allocated to
	    LogicalVolumePath and less than 65535 which is the implementation
	    limit.
	    LogicalExtentsNumber represents the new total number of logical
	    extents that can be allocated to LogicalVolumePath.	 The change
	    is accomplished by allocating the number of additional logical
	    extents represented by the difference between
	    LogicalExtentsNumber and the previous number of extents.
	    The mirror policy and mirror copies number for the new logical
	    extents is the same as previously established for the
	    LogicalVolumePath.
	    Either this option or the -m option must be supplied.

  -m MirrorCopies
	    Sets the number of physical extents allocated for each logical
	    extent.
	    MirrorCopies (that is, mirrors) can be either 1 or 2. This means
	    that beyond the original copy, one or two mirror copies will
	    contain the same data as the original copy.	 MirrorCopies  must
	    be greater than the current number of mirrors for the logical
	    volume.
	    The data in the new copies are synchronized. The synchronization
	    process can be time consuming, depending on the hardware
	    characteristics and the amount of data.  If the allocation policy
	    for the logical volume is strict and the specified physical
	    volume already contains logical extents of the logical volume,
	    the request is rejected.
	    Either this option or the -l option must be supplied.

EXAMPLES
   1.  To increase the number of the logical extents of logical volume lv03
       up to one hundred, enter:
	    lvextend -l	 100  /dev/vg01/lv03

   2.  To get two mirrors (that is, three copies) for each logical extent of
       logical volume lv05, enter:
	    lvextend -m	 2   /dev/vg01/lv05
       Each logical extent of logical volume lv05 is now doubly mirrored.
