Glossary
nominal membership
The desired number of mirrorset members when the mirrorset is fully populated with active
devices. If a member is removed from a mirrorset, the actual number of members may 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 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.
OCP
Operator control panel. The control and indicator panel associated with an array controller.
The OCP is mounted on the controller and is accessible to the operator.
