LAN
Local area network.
lb.
Pound.
LCP
Local control port.
LD, LDEV
Logical device. An LDEV is created when a RAID group is carved into pieces
according to the selected host emulation mode (that is, OPEN-3, OPEN-8, or
OPEN-9). The number of resulting LDEVs depends on the selected emulation mode.
The term
LDEV
is often used synonymously with the term
volume
.
LED
Light emitting diode.
local disk
A local disk in the host.
local instance
The instance currently being configured or the instance to which commands are issued.
LPAR
Logical partition.
LCP
Link control processor or local control port.
LRU
Least recently used.
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.
LVI
Logical volume image.
LVM
Logical Volume Manager.
LVM mirror
A disk duplicating function provided by Logical Volume Manager (LVM) (capable of
triplicating disks).
m
Meters.
