vgextend(8)
NAME
  vgextend - Extend a volume group by adding physical volumes to it

SYNOPSIS
  /usr/sbin/vgextend [-x Extensibility] [-v VGDA] VolumeGroupName
  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 vgextend assigns physical volumes to the VolumeGroupName.	 The volume
  group must be active.

  You extend the volume group by adding one or more physical volumes
  represented by the PhysicalVolumePath parameter(s).

  After the physical volumes have been successfully added to the volume
  group, they can be used.

  Before assigning a physical volume to a volume group, you must create the
  physical volume with the pvcreate command.

  If, for any reason, one of the remaining specified physical volumes cannot
  be installed into the volume group, an error message is printed.  However,
  the installation continues to the end of the list of physical volumes.

FLAGS
  -x Extensibility
	    Sets the allocation permission for additional physical extents on
	    the physical volume specified by the PhysicalVolumePath
	    parameter.	The Extensibility  parameter is represented by one of
	    the following:

	    y	      Allows the allocation of additional physical extents on
		      the physical volume.  (The default.)

	    n	      Prohibits the allocation of additional physical extents
		      on the physical volume. The logical volumes that reside
		      on the physical volume can still be accessed.

  -v VGDA   This option allows you to specify if a VGDA (Volume Group
	    Descriptor Area) of the volume group must be stored on the
	    physical volume.  VGDA is represented by one of the following:

	    y	      Allows the creation of a VGDA on the physical volume.
		      (The default.)

	    n	      Prohibits the creation of a VGDA on the physical
		      volume.

EXAMPLES
  This section contains a Digital device-specific example.

  To add physical volumes rz3c and rz4c to volume group vg03, enter:

       vgextend /dev/vg03  /dev/rz3c  /dev/rz4c

  The physical volumes rz3c and rz4c now belong to volume group vg03.
