IPL. See initial program load.
K
Keep. When a stacked physical volume is borrowed
from the Common Scratch Pool (CSP) and it is not to
be returned to the CSP when it is reclaimed.
KEK. Key Encrypting Key. An alphanumeric string
used to encrypt the Data Key. See EEDK.
keystore. A database of private encryption keys and
their associated digital certificate chains used to
authenticate the corresponding public keys.
L
LAN. See local area network.
Library Manager. The controller for the 3494 Tape
Library. It manages the location of tape cartridges,
monitors performance, issues commands to the
hardware, displays status, and performs other
functions. It communicates with host systems through
the tape control unit in each library or, in AS/400 and
iSeries, directly through the RS-232 interface. The
Library Manager also provides operator and service
panel functions.
load. (1) The process, performed by an operator or by
the cartridge accessor, of placing a cartridge into a
location within the tape library for later use or
retrieval. (2) The term used when describing the action
of the tape transport when it removes the leader block
from a cartridge and threads the media through the
internal tape path.
local area network. A computer network located on a
user's premises within a limited geographical area.
Communication within a LAN is not subject to external
regulations; however, communication across a LAN
boundary may be subject to regulation.
M
manual mode. A mode of operation, where the
operator, under the direction of the Library Manager,
locates and moves tape cartridges to and from storage
cells and tape units manually. This mode allows data to
be retrieved when normal tape library operations are
interrupted by unexpected conditions.
MES. Miscellaneous Equipment Specification.
migrate. Move virtual volume data from the VTS
cache to a physical stacked tape.
mount. A host command to load a cartridge into a
tape unit.

mount from input station. A function available
through the Commands window on the Library
Manager. It allows transient cartridges outside the
library to be mounted on devices within the library. It
is used to support stand-alone programs that do not
require the support of a full operating system.
N
NEMA. National Electrical Manufacturers'
Association.
No Borrow. When a storage pool is out of scratch
stacked volumes, no volumes will be borrowed from
the Common Scratch Pool.
non-user interface VTS. The VTS in a Peer-to-Peer
VTS configuration that was not selected as the user
interface VTS. The non-user interface VTS is the
secondary VTS in the configuration. User applications
do not recognize the non-user interface VTS.
O
OEMI. See original equipment manufacturers interface.
offline. Pertaining to the operation of a unit when not
under the direct control of a host system. Compare
with unavailable. Contrast with online.
online. Pertaining to the operation of a unit when
under the direct control of a host system. Compare
with available. Contrast with offline.
original equipment manufacturers interface. A
common communication interface that allows
connection from a host to a tape drive.
P
Peer-to-Peer VTS. A VTS configuration in which
copies of data in newly created or updated tape
volumes are created or updated automatically in each
of two interconnected VTSs. This dual-volume copy
functionality improves data availability and data
recovery, while being transparent to user applications
and host processor resources.
program temporary fix. A temporary solution to, or
bypass of, a defect in a current release of a licensed
program.
PTF. See program temporary fix.
R
recall. Move data from a stacked physical tape to the
VTS cache.
