Yes you can. What you have to do is basically create your logical volume by just assigning a name and then when you extend you specify the disk.

# lvcreate -n lvol10 vg01
# lvextend -l 300 /dev/vg01/lvol10 /dev/dsk/c1t1d0

Hi Jerry:

Yes, in two steps. You must allocate the logical volume with a ZERO-size with 'lvcreate'. Then, use 'lvextend' to specify the real size (increase) and specify the *physical* volume then. See the man pages for 'lvcreate' and 'lvextend' for more information.

lvcreate and then lvextend.

lvextend -L new_size lvol_name pv_name.

or you user pvmove also.

Check man pages.

Yes. Create the LV with "0" size first (lvcreate) and then use lvextend command to extend the LV to the required size and specify the pv name there:

# lvcreate -L 0 lv_name
# lvextend -L new_or_required_size lv_name pv_path
