ACB
Alternate Control Block is a subset of the
InitFW block of firmware parameters in
Flash
memory.
AL_PA
Arbitrated loop_physical address, a
low-level address on the FC loop.
arbitrated loop
A non-point-to-point circular topology
where two or more
port
s can be intercon-
nected, but only two ports can communi-
cate at one time. All communication is
passed through all ports connected onto
the loop.
ARP
Address resolution protocol. An Internet
protocol used for mapping an IP address
to a physical address on an Ethernet LAN.
BIOS
Basic input/output system. A QLA2
xxx
HBA
's flash PROM contains the code that
allows booting from the HBA at startup.
boot code
The first program to run when a system is
powered on. This is also true for devices
within a system, such as
FC
HBA
s.
FCode
,
BIOS
, and EFI (enhanced
firmware interface) are all forms of boot
code for specific hardware/operating
system environments.
Boot code for QLogic FC HBAs is required
if the computer system is booting from a
storage device (boot device) attached to
the QLogic HBA. The primary function of
the boot code is communication with the
external boot device before the operating
system is up and running. There are also
secondary functions that can be performed
by the boot code, including managing the
setup for the HBA and initializing and
testing the HBA’s ISP.
boot device
The hard disk that contains the operating
system that the
BIOS
uses to boot from
when the computer is started.
core dump
The recorded state of the working memory
of a computer program at a specific time,
generally when the program has termi-
nated abnormally. Core dumps are often
used to diagnose or debug errors in
computer programs.
CRC
Cyclic Redundancy Check. A CRC is a
type of check value designed to catch
most transmission errors.
CSV file
Comma separated values file.
