lvextend -L 400 /dev/vg01/lvol4
Allocate two mirrors (that is, two copies of the original) for each logical extent of a logical volume:
lvextend -m 2 /dev/vg01/lvol5
Mirror a logical volume onto a particular physical volume.
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c0t3d0
Increase the size of a file system existing on a logical volume.

Unmount the file system.
umount /dev/vg06/lvol3
