Glossary
AL_PA
Arbitrated-loop physical address. A unique 8-bit value assigned during loop initialization to a port in an arbitrated
loop. Alternately, “arbitrated-loop parameters.”
alias
A logical grouping of elements in a fabric. An alias is a collection of port numbers and connected devices, used to
simplify the entry of port numbers and WWNs when creating zones.
ARB
Arbitrative primitive signal. Applies only to an arbitrated-loop topology. Transmitted as the fill word by an L_Port to
indicate that the port is arbitrating access to the loop.
area number
In HP Fabric OS v4.0 and above, ports on a switch are assigned a logical area number. Port area numbers can be
viewed by entering the switchshow command. They are used to define the operative port for many Fabric OS
commands: for example, area numbers can be used to define the ports within an alias or zone.
ASIC
Application-specific integrated circuit.
authentication
The process of verifying that an entity in a fabric (such as a switch) is what it claims to be. See also digital certificate.
autocommit
A feature of the firmwaredownload command. Enabled by default, autocommit commits new firmware to both
partitions of a control processor.
autoreboot
Refers to the -b option of the firmwaredownload command. Enabled by default.
backbone fabric
An optional capability that enables scalable meta-SANs by allowing the networking of multiple FC routers, which
connect to the backbone fabric via EB_Port interfaces.
backup FCS switch
Relates to the HP Secure Fabric OS feature. The backup fabric configuration server serves as a backup in case the
primary FCS switch fails. See also FCS switch, primary FCS switch.
BB fabric
A backbone fabric that connects FC Routers. The FC Routers communicate over the backbone fabric using FCRP
(Fibre Channel Router Protocol).
BB_Credit
Buffer-to-buffer credit. The number of frames that can be transmitted to a directly connected recipient or within an
arbitrated loop. Determined by the number of receive buffers available. See also buffer-to-buffer flow control,
EE_Credit.
