Numeric

9490 A device that reads from or writes to a 3480
tape, ETape, or EETape. Also referred to as
TimberLine.
9741 A drive cabinet that attaches to the rear
of the LSM. It contains DLT drives, T9840 drives,
or both.

A

ACSLS Automated Cartridge System Library
Software.
audit (1) For an LSM, a part of its IPL
sequence that catalogs all cartridge locations within
the LSM cells and retains the data in the library
controller card's memory.
(2) For a host, its request to catalog the cartridges
in an LSM by LSM number, panel, row, and
column.
automatic mode A relationship between an LSM
and all attached hosts. An LSM operating in
automatic mode handles cartridges without
operator intervention. This is the normal operating
mode of an LSM that has been placed online to all
host CPUs.

C

CAP See cartridge access port.
cartridge The plastic housing around the tape. A
plastic leader block is attached to the tape for
automatic threading when loaded in a drive. The
spine of the cartridge contains a VOLSER label
listing the volume identification number. The
media ID label allows cartridge capacity to be
identified.
cartridge access port (CAP) A device in the
library that allows an operator to insert or remove
cartridges during library operations.
cartridge drive (CD) A device containing two or
four cartridge transports with associated power
and pneumatic supplies.
cartridge exchange mechanism (CEM) A
mechanism that allows a cartridge to pass from
one library storage module (LSM) to another in a
multiple LSM automated cartridge system.
