Glossary
Ethernet
A widely implemented local area network (LAN) protocol that uses a bus or star topology and
serves as the basis for the Institute of Electrical and Electronics Engineers (IEEE) 802.3
standard, which specifies the physical and software layers.
Ethernet hub
A device used to connect the HAFM server and the directors it manages.
event code
A three-digit number that specifies the exact event that occurred. This code provides
information on system failures, such as hardware failures, failure locations, or general
information on normal system events.
Event Log
Record of significant events that have occurred on the director or switch (director or switch
Event Log) or through the HAFM Services application (HAFM Event Log). There are two
Event Logs: director or switch Event Log, and HAFM Event Log.
(1) Director or switch Event Log. Log displayed through the Product Manager application that
provides a history of events for an individual director or switch, such as system events,
degraded operation, FRU failures, FRU removals and replacements, port problems, Fibre
Channel link incidents, and HAFM server-to-product communication problems. All detected
software and hardware failures are recorded in the Event Log. The information is useful to
maintenance personnel for fault isolation and repair verification. Contrast with HAFM Event
Log. See also Audit Log; Hardware Log; Link Incident Log; Threshold Alert Log.
(2) See HAFM Event Log.
exchange
A term that refers to one of the Fibre Channel protocol “building blocks,” composed of one or
more nonconcurrent sequences.
expansion port
E_Port. Physical interface on a Fibre Channel switch within a fabric, that attaches to an E_Port
on another Fibre Channel switch through an interswitch link (ISL) to form a multiswitch
fabric. See also bridge port; fabric port; generic port; node port; segmented expansion port.
