GL–12 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
network A data communication, a configuration in which two or more terminals or
devices are connected to enable information transfer.
node In data communications, the point at which one or more functional units
connect transmission lines.
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.
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.
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.
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 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.
