LD, LDEV Logical device. An LDEV is created when a RAID group is divided into

sections using a selected host emulation mode (for example, OPEN-9 or

OPEN-M). The number of resulting LDEVs depends on the emulation mode.

The term LDEV is often used synonymously with the term volume.

LU Logical unit.

LUN Logical unit number. A LUN results from mapping a SCSI logical unit

number, port ID, and LDEV ID to a RAID group. The size of the LUN is

determined by the emulation mode of the LDEV, and the number of LDevs

associated with the Lun. For example, a LUN associated with two OPEN-3

LDEVs will have a size of 4,693 MB.

LUSE Logical Unit Size Expansion, a feature which logically combines LDEVs

so they appear as a larger LDEV. This allows a LUN to be associated with 2

to 36 LDEVs. Essentially, LUSE makes it possible for applications to

access data requiring a large amount of disk space.

LVM Logical Volume Manager.

MB Megabytes.

MPE Maximum physical extent.

OFC Open Fibre Control.

OPEN-x A general term describing any one of the supported OPEN emulation

modes (for example, OPEN-3, OPEN-9, OPEN-L).

Supported emulation modes: OPEN-3/8/9/E/L.
