The logical volume manager enables you to span a volume that is visible to the user over several physical volumes.
Let's assume you want to group sdi, sdj, sdk and sdl to one big disk.
First prepare the physical volumes:
pvcreate /dev/sdi pvcreate /dev/sdj pvcreate /dev/sdk pvcreate /dev/sdl
Then create a volume group
vgcreate vg1 /dev/sdi /dev/sdj /dev/sdk /dev/sdl
