in the I/O stations. The screen also
indicates the current activity being
performed, the volume serial (VOLSER)
number of the cartridge associated with
the activity, and a history of previous
activities. The Activity screen leads to the
Main Menu.

See adapter card.
adapter card
A circuit board that adds function to a
computer.
addressable cartridge storage slots
See accessible cartridge storage slots.
Advanced Interactive eXecutive (AIX)
A UNIX operating system developed by
IBM that is designed and optimized to
run on POWER
hardware such as servers, workstations,
and blades.
Advanced Library Management System (ALMS)
The next generation of IBM's patented
Multi-Path Architecture. ALMS enables
logical libraries to consist of unique
drives and ranges of VOLSERs, instead of
fixed locations. It offers the ability to
assign tape drives to any logical library
by using the IBM System Storage Tape
Library Specialist Web interface. Logical
libraries can also be added, deleted, or
easily changed without disruption.
aggregate sustained data transfer rate
For all of the drives in the TS3500 Tape
Library, the sum of their average
throughput of uninterrupted data.

alphanumeric
Pertaining to a character set that contains
letters, numerals, and usually other
characters, such as punctuation marks.
alternating current (ac)
An electric current that reverses its
direction at regularly recurring intervals.

microprocessor-based
is equivalent to a flow of one coulomb
per second, or to the current produced by
one volt applied across a resistance of one
ohm.
Arbitrated Loop Physical Address (AL_PA)
An 8-bit value used to identify a device in
an arbitrated loop. Device ports
communicate by using AL_PAs.
audit The process of moving cartridges in an
HD slot in order to scan each barcode
label.
authorized assembler program (AAP)
A training program for selected IBM
Business Partners that enables them to
purchase incomplete machines and parts,
and provides them with the knowledge to
assemble the components into a final
configured product for sale to customers.
automatic cleaning
A method by which the TS3500 Tape
Library automatically responds to any
tape drive's request for cleaning by
beginning the cleaning process. An
operator enables automatic cleaning by
using the menus on the library's
touchscreen or the web interface.
automatic inventory
A survey of the location of cartridges in
the TS3500 Tape Library. The library
performs the survey at power-on or
whenever the front door of any frame is
opened and closed during operation.
B
backhitch
When the speed of the host server is
slower than that of the drive, the action of
stopping the tape, rewinding some
distance, and restarting.
backup
The short-term retention of records used
for restoring essential business and
system files when vital data has been lost
because of program or system errors or
malfunctions.
Backup recovery and media services (BRMS)
A software program that runs on OS/400
and allows a business to plan, control,
and automate the backup, recovery, and
media management services for its
AS/400 systems.
