Glossary
This section describes common hardware, software, and Fibre Channel terms that
are used in the SANsurfer FC HBA Manager.
Adapter See HBA.
AL_PA AL_PA stands for arbitrated loop_physical address.
This is a low-level address on the Fibre Channel loop.
Arbitrated loop An arbitrated loop is a non-point-to-point circular
topology where two or more ports can be
interconnected, but only two ports can communicate at
one time. All communication is passed through all ports
connected onto the loop.
BIOS A QLA200/QLA2xxx HBA’s flash PROM contains the
code that allows booting from the HBA at startup.
Boot code Boot code is the first program to run when a system is
powered on. This is also true for devices within a
system, such as FC HBAs. 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 boot device is the hard disk that contains the
operating system the BIOS uses to boot from when the
computer is started.
CSV file A comma separated values (CSV) file.
