vgextend - add physical volumes to a volume group
vgextend [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test]
  [-v|--verbose] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]
vgextend allows you to add one or more initialized physical volumes ( see
  pvcreate(8) ) to an existing volume group to extend it in size.
See lvm for common options.
"vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing
  volume group "vg00" by the new physical volumes (see
  pvcreate(8) ) "/dev/sdn1" and /dev/sda4".
