Glossary
nondisruptive maintenance
Ability to service FRUs (including maintenance, installation, removal and replacement) while
normal operations continue without interruption. See also
N_Port
See
node
port.
offline
R
eferring to data stored on a medium, such as tape or even paper, that is not available
immediately to the user.
offline diagnostics
Diagnostics that only operate in stand alone mode. User operations cannot take place with
offline diagnostics running.
offline sequence
(OLS) — Sequence sent by the transmitting port to indicate that it is attempting to initialize a
link and has detected a problem in doing so.
offline state
When the switch or director is in the offline state, all the installed ports are offline. The ports
transmit an offline sequence (OLS) and they cannot accept a login connection from an attached
device. See also

OLS
See
offline
sequence.
online state
When the switch or director is in the online state, all of the unblocked ports are allowed to log in
to the fabric and begin communicating. Devices can connect to the switch or director if the port
is not blocked and can communicate with another attached device if both devices are in the
same zone, or if the default zone is enabled. See also
Open Systems Architecture
OSI. A model that represents a network as a hierarchical structure of functional layers. Each
layer provides a set of functions that can be accessed and used by the layer above. Layers are
independent, in that implementation of a layer can be changed without affecting other layers.
open-systems interconnection
A model that represents a network as a hierarchical structure of functional layers. Each layer
provides a set of functions that can be accessed and used by the layer above. Layers are
independent, and the implementation of a layer can be changed without affecting other layers.
Open Systems Management Server
An optional feature that can be enabled on the director or switch through the Element Manager
application. When enabled, host control and management of the director or switch are provided
through an open systems interconnection (OSI) device attached to a director or switch port.
