Glossary

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.AL_PA

Arbitrated loop physical address. A unique 8-bit value assigned during loop initialization to a port in an

arbitrated loop.

area number

In Fabric OS 4.0 and later, ports on a switch are assigned a logical area number. Port area numbers can

be viewed by issuing 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.

CLI

Command line interface. An interface that depends entirely on the use of commands, such as through

telnet or SNMP, and does not involve a GUI.

compact flash

Nonvolatile storage that is used in a manner similar to hard disk storage. It is connected to a bridging

component that connects to the PCI bus of the processor.

configuration

1. A set of parameters that can be modified to fine-tune the operation of a switch. Use the configShow

command to view the current configuration of your switch.

2. In HP Advanced Zoning, a zoning element that contains a set of zones. The configuration is the

highest-level zoning element and is used to enable or disable a set of zones on the fabric. See also zone

configuration.

core PID

Core switch port identifier. This PID format supports higher port count switches and is the default mode for

all Fabric OS 4.x switches. The core PID format must be set for all Fabric OS 3.x and earlier switches, if

any version 4.x switch is included in a fabric. See also native PID, extended edge PID.

CSCN

Common service connection.

CSDBG

Common services debug framework.

CSMSG

Common services messaging service.

DAP

A device address: domain:areaID:AL_PA

DLS

Dynamic load-sharing. Dynamic distribution of traffic over available paths. Allows for the recomputing of

routes when an Fx_Port or E_Port changes status.

domain ID

A unique identifier for all switches in a fabric; used in routing frames. Usually assigned by the principal

switch, but can be assigned manually. The domain ID for an HP StorageWorks switch can be any integer

between 1 and 239.
