Glossary
This glossary defines terms and abbreviations
used in this manual. For definitions of other Fibre
Channel or StorageTek terms refer to the
glossary in the appropriate document.
Numbers
8B/10B A type of encoding and decoding
algorithm of bytes, invented and patented by
IBM, to reduce transmission errors. This
algorithm was adopted as part of the FC-PH-1
Standard in 1991.
A
Abort Exchange (ABTX) The Abort Exchange
command can be used with Abort Sequence -
Last Sequence (ABTS - LS) (SCSI-PLDA), by
itself, or with ABTS Fibre Channel Link
Encapsulation (FC-LE) protocol. The Abort
Exchange Command used in the Extended Link
Services, and is prohibited when originated by
the initiator, and is prohibited when originated by
a drive.
Abort Sequence (ABTS) The protocol that is
invoked by devices supporting the Fibre Channel
Protocol for SCSI to abort the exchange
whenever a Sequence Error is detected. It
comes in two protocols: Abort Sequence - Last
Sequence (ABTS - LS) (SCSI-PLDA), by itself, or
with ABTS Fibre Channel Link Encapsulation
(FC-LE).
ABTS See Abort Sequence.
ABTX See Abort Exchange.
ACA Auto Contingent Alliance.
ACC Accept.
ACK See Acknowledge.
Acknowledge A response or confirmation to an
address, message, or poll.
Additional Sense Bytes The additional sense
bytes contain data specific to either or both the
command or peripheral device, and further
define the nature of the FCP_SNS_INFO feature
of the FCP_RSP payload.
Addressing Scheme The order in which node
and port names are presented to the recipient in
a Fibre Channel transaction.
ADISC See Discover Address.
ADVC See Advise Credit.
Advise Credit The Advise Credit Command
used in Extended Link Services. It is prohibited
when originated by the initiator, and prohibited
when originated by a drive.
AEN See Asynchronous Event Notification.
AL_PA See Arbitrated Loop Physical Address.
AL_PD Arbitrated Loop physical destination
address.
AL_PS Arbitrated Loop physical source
address.
AL_TOV Arbitrated loop timeout value.
Allowable A function of Fibre Channel that
allows a feature or parameter to be used
between an initiator and a target.
American National Standards Institute A
standards development organization that is not
associated with the U.S. government, but that
develops standards that can be used voluntarily
by product vendors in the United States. The
name of the organization was recently changed
to the National Committee for Information
Technology Standards (NCITS).
ANSI See American National Standards
Institute.
Arbitrate to win loop In an arbitrated loop
topology, the process that a port performs to
