Glossary 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. Fabric OS Version 3.1.x/4.1.x Reference Guide 967
