indicator A device that provides a visual or other
indication of the existence of a defined state. (T)
initialization The operations required for setting
a device to a starting state, before the use of a data
medium, or before implementation of a process.
(T)
initial program load (IPL) 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.
interface Hardware, software, or both, that links
systems, programs, or devices. (IBM)
Internet Protocol (IP) A stacked set of
protocols, developed by the United States
Department of Defense, to facilitate
communication between dissimilar computers over
networks.
Internet Protocol (IP) address A four-byte
value that identifies a library and makes it
accessible through a network. IP addresses are
logically divided into two parts: the network
(similar to a telephone area code), and the system
on the network (similar to a phone number). See
also Ethernet address, library name, subnet mask.
intervention required Operator action is
required (such as removing a cartridge from the
drive).

kb See kilobit.
kB See kilobyte.
kilobit (kb) (1) One thousand bits (10³ bits). (2)

1,024 bits (2

kilobyte (kB) (1) One thousand bytes (10³ bytes).

kilovolt-ampere (kVA) An electrical unit of
power equal to one thousand volt-amperes.
kVA See kilovolt-ampere.
L
label An identifier associated with a removable
media or cartridge. Labels may be humanly
readable, machine readable, or both. Synonymous
with VOLSER and volume serial number.
lb An abbreviation for pound.
leader block. The mechanism that loads the tape
through the tape path of a drive.
Library Admin See StorageTek L-Series Library
Admin.
library name An assigned name that maps to the
Internet Protocol (IP) address for a library. See also
Ethernet address, Internet Protocol (IP) address,
subnet mask.
Library Status tool A proprietary software that
resides internal to the library and is activated using
a Web browser. It is used to monitor the library,
load code, reboot library, and to generate reports
on library, drives, fault symptom codes (FSCs), and
tape inventory.
Linear Tape-Open (LTO) A technology
developed jointly by HP, IBM, and Seagate for new
tape storage options. LTO technology is an open
format, which means that users have multiple
sources of products and media. The open nature
of LTO technology also provides a means of
enabling compatibility between different vendors'
offerings.
low voltage differential (LVD) A type of SCSI
interface. LVD interface restricts cable lengths, 12
m (30.4 ft), but provides faster throughput.
M
m See meter.
mA Milliampere or one one-thousandth (10
an ampere.
