Command Line Interface Reference Guide
node
In data communications, the point at which one or more functional units connect
transmission lines. In Fibre Channel, a device that has at least one N_Port or NL_Port.
nominal membership
The desired number of mirrorset members the mirrorset is fully populated with active
devices. If a member is removed from a mirrorset, the actual number of members can fall
below the “nominal” membership.
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 are 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.
nonredundant controller configuration
(1) A single controller configuration. (2) A controller configuration that does not include a
second controller.
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
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 is written since the mirrorset was created or lost cache data was
cleared. A normalizing member is created by a normal member either all of the normal
members fail or all of the normal members are removed from the mirrorset. See also
copying member.
OCP
Operator control panel. The control and indicator panel associated with a controller. The
OCP is mounted on the controller and is accessible to the operator
operator control panel
