2. Choose System Storage Management (Physical and Logical Storage) from the
System Management menu.
3. Choose Logical Volume Manager from the System Storage Management menu.
The Logical Volume Manager menu is displayed on the Logical Volume Manager
screen. You will be using menu options from this menu to create a volume group and
then a logical volume within this volume group.
Volume groups are a way of dividing and allocating disk storage capacity. Volume
groups can be used to subdivide a large partition of storage into smaller units of usable
space called logical volumes.
Each volume group is divided into logical volumes, which are seen by applications as
individual disks. Logical volumes can contain their own file systems.
The underlying physical storage in a volume group consists of one or more physical
volumes. A physical volume can be a single physical disk or a partition of a disk array.
In this appendix, the physical volume is the disk device you identified in “Identifying
the Device on Which You Will Create a Logical Volume” on page H-4.
H.5 Creating a Volume Group

2. Choose Add a Volume Group from the Volume Groups menu.
3. Type the name you want to give the volume group next to VOLUME GROUP name.

in “Identifying the Device on Which You Will Create a Logical Volume” on page H-4.
An “ARE YOU SURE” confirmation screen is displayed.
5. Confirm this message to display a status screen.
When the volume group is created, a status screen displays “Command: OK.”
