Intrepid® 6064 Director Installation and Service Manual
Glossary
link incident The interruption of traffic on a Fibre Channel link due to loss of light
or other malfunction.
Link Incident Log A log recorded at the Element Manager application that displays a
history of Fibre Channel link incidents (with associated port
numbers) for a director or switch.
LIP sequence See loop initialization primitive sequence.
local area network A communication system that links computers in a network through
a wiring-based cable scheme. LANs connect servers, storage devices,
and printers together to allow users to communicate and share
resources. LAN devices are linked in a localized geographical area
(for example, a building or campus), and are typically user-owned
and do not run over leased lines. Contrast with metropolitan area
network, storage area network, and wide area network.
logical port address The address used to specify port connectivity parameters when a
director or switch is set to operate in S/390 mode.
logical unit number In systems network architecture, a LUN is a number assigned to each
logical partition of a storage device. Each logical partition is uniquely
identified in a SAN when the LUN combines with the WWN of the
storage device’s N_Port.
loop initialization
primitive sequence
A transmitted LIP sequence enables initialization of a Fibre Channel
arbitrated loop. An arbitrated loop must initialize prior to operation
and when configuration changes are detected. Any FL_Port with a
valid AL_PA can start loop initialization by entering the initializing
state and transmitting a LIP sequence.
LUN See logical unit number.
M
MAC address See media access control address.
maintenance port Connector on a director or switch whereby a PC running an ASCII
terminal emulator can be connected for specialized maintenance
support.
MAN See metropolitan area network.
