The above screen shows each logical volume and the number of logical partitions,
number of copies, stripe size and number of physical volumes currently assigned
to the logical volume. Select a logical volume and press Enter. A screen similar to
the following is then displayed, showing a list of physical volumes currently
assigned to the volume group in which the logical volume exists:
Select a physical volume and press Enter. The physical volume to use must first be
assigned to this volume group using the Select Physical Volumes for Volume
Groups menu. To deselect a currently selected physical volume, select the volume
and press Enter.
Note: Although you can specify specific physical volumes where a logical volume
is placed, there is no guarantee that the logical volume will be placed only
on those disks unless you create the logical volume using a physical
partition map. Verification ensures that adequate space exists in the volume
group for all of the logical volumes, but no checks are made to ensure there
is adequate space on each disk to satisfy the logical volume selections. If
there is not adequate space on the physical volumes when the logical
volume is created, it is created using the first available space in the volume
group.
When changes are complete, press Esc to return to the previous menu.
