However if you use a Logical VOlumn Manager (LVM) you can make one disk look like several disks. This means rather then having one device in /dev you have several each corresponding to part of the disk. I have used HP's Logical Volumn Manager under HP-UX 9.04 to make 3*9 Gig drives look like 14*2 Gig drives with no problem. -- David Williams
