NL_port A port attached to a node for use in all three topologies.
network A data communication, a configuration in which two or more terminals or
devices are connected to enable information transfer.
Non-L_Port A Node of Fabric port that is not capable of performing the Arbitrated Loop
functions and protocols. N_Ports and F_Ports loop-capable ports.
non-participating mode A mode within an L_Port that inhibits the port from participating in loop
activities. L_Ports in this mode continue to retransmit received transmission
words but are not permitted to arbitrate or originate frames. An L_Port in
non-participating mode may or may not have an AL_PA. See also
participating mode.
node 1. In data communications, the point at which one or more functional units
connect transmission lines.
2. In Fibre Channel, a device that has at least one N_Port or NL_Port.
normal member A mirrorset member that, block-for-block, contains the same data as other
normal members within the mirrorset. Read requests from the host are always
satisfied by normal members.
normalizing Normalizing is a state in which, block-for-block, data written by the host to a
mirrorset member is consistent with the data on other normal and
normalizing members. The normalizing state exists only after a mirrorset is
initialized. Therefore, no customer data is on the mirrorset.
normalizing member A mirrorset member whose contents is the same as all other normal and
normalizing members for data that has been written since the mirrorset was
created or lost cache data was cleared. A normalizing member is created by a
normal member when either all of the normal members fail or all of the
normal members are removed from the mirrorset. See also copying member.
OC-3 A term used to express the optical carrier that provides high-speed bandwidth
at 155.3 megabits per second.
other controller The controller in a dual-redundant pair that is not connected to the controller
serving your current CLI session with a local terminal.
See also this controller, local terminal.
participating mode A mode within an L_Port that allows the port to participate in loop activities.
A port must have a valid AL_PA to be in participating mode.
