Ordered Set
A transmission word that uses 8B/10B mapping and begins with the K28.5 character. Ordered sets
occur outside of frames, and include the following items:
■ Frame delimiters: Mark frame boundaries and describe frame contents.
■ Primitive signals: Indicate events.
■ Primitive sequences: Indicate or initiate port states.
Ordered sets are used to differentiate Fibre Channel control information from data frames and to
manage the transport of frames.
Packet
A set of information transmitted across a network.
See also Frame.
Participating Mode
A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send frames, and
retransmit received transmissions.
See also L_Port, Non-participating Mode.
Path Selection
The selection of a transmission path through the fabric. HP StorageWorks switches use the FSPF
protocol.
Performance Monitor
Comprehensive HP tool for monitoring the performance of networked storage resources.
Performance Monitoring
An HP product that provides error and performance information to the administrator and end user
for use in storage management.
Phantom Address
An AL_PA value that is assigned to an device that is not physically in the loop.
Also known as phantom AL_PA.
Phantom Device
A device that is not physically in an arbitrated loop, but is logically included through the use of a
phantom address.
PLOGI
Port Login. The port-to-port login process by which initiators establish sessions with targets.
See also FLOGI.
