mklv Command
Purpose
Creates a logical volume.
Syntax
mklv [ -mirror ] [ -lv NewLogicalVolume | -prefix Prefix ] VolumeGroup Size [ PhysicalVolume ... ]
Description
The mklv command creates a new logical volume within
the VolumeGroup. If you specify one or more physical
volumes with the PhysicalVolume parameter, only those
physical volumes are available for allocating physical partitions; otherwise,
all the physical volumes within the volume group are available.
The allocation policy is to use a minimum number of physical volumes.
The Size parameter specifies the minimum size the
logical volume should be. When specifying Size the following conventions must
be used:
| Size |
Logical volume size |
| ###M/m |
### MB |
| ###G/g |
### GB |
Flags

using a system-generated name. Logical volume names must be unique system
wide name, and can range from 1 to 15 characters. |
| -mirror |

| -prefix |
Specifies the Prefix to use instead of the prefix in
a system-generated name for the new logical volume. The prefix must be less
than or equal to 13 characters. The name cannot begin with a prefix already
defined in the PdDv class in the Device Configuration
Database for other devices, nor be a name already used by another device. |
