[Sajjad Sahir]

[Steven E. Protter]

Shalom,

Have to know whether the logical volumes are raw disk or not.

I'll assume you have disk allocated.

Further I'll assume that the volume group already exists.

The fact I've just used the word assume twice(3) times means you have not provided enough detail about your environment.

vgextend vgdb /dev/dsk/c1t1d0
# use real vg and disk.
lvcreate -n newlvol vgdb /dev/dsk/c1t1d0
# use real vg and disk.
lvextend -L /de/vgdgb/newlvol /dev/dsk/c1t1d0

newfs to format a filesystem if needed.
