  • vgdisplay
    • uses volume group device as argument f.e. /dev/vg00
  • lvdisplay
    • uses logical volume block device as argument
  • mediainit
    • formats disk and confirms integrity. uses raw / character device file!
  • pvcreate
    • creates physical volume using raw device file

    • vgcreate /dev/vg02 /dev/dsk/c2t5d0
