144 StreamLine™ SL8500 Modular Library System User's Guide • March 2007 Revision K • 96154
home libraryIn a library complex of two or more SL8500 libraries connected by PTPs, the
library that supplies power and signals to the pass-thru port on its left side (as
viewed from the front of the libraries). See also away library.
host auditThe process of updating the cartridge VOLIDs and locations (collected by a
security audit) in a host CDS. This audit is initiated by a host command.
Host Software Component
(HSC)A host-resident software package that controls an automated cartridge system
(ACS). After synchronizing with the target library (or libraries), HSC records cell
status, allocates devices, and automates mount and dismount requests from the
host.
hot swapRemoval and replacement of a system component while system power remains on
and system operations continue. Contrast with cold swap. Contrast with hot-
pluggable.
Synonymous with online servicing.
hot-pluggableThe capability that allows a service representative to replace FRUs while power to
the FRU is maintained. This feature allows hardware maintenance actions and
hardware upgrades to proceed without disrupting subsystem availability. Contrast
with hot swap.
HSCSee Host Software Component.
I
importThe process of placing a cartridge into the cartridge access port so that the library
can insert it into a storage slot.
Synonymous with enter.
initial program load
(IPL)(1) A process that activates a machine reset and loads system programs to prepare
a computer system for operation. Processors having diagnostic programs activate
these programs at initial program load execution. Devices running firmware
usually reload the functional firmware from a diskette or disk drive at initial
program load execution. Synonymous with initial microprogram load (IML). (from
the GLS Glossary)
(2) The initialization procedure that activates a machine reset, initiates wake-up
diagnostics (from EPROMs) and loads functional code. (from the GLS Glossary)
interlock switchA switch that disconnects power to library mechanisms, excluding tape drives,
when the front door is opened.
IPLSee initial program load.
