The
service
representative
has
full
authorization
access
to
all
functions
of
the
3494
Tape
Library.

you
choose
to
use
password
protection,
the

the
Library

Each
time
a
user
enters
a
part
of
the
application
that
requires
a
password,
then
enters
a
password,
a
log
entry
is
made
at
the
Library
Manager.
Exiting
a
protected
menu
also
creates
a
log
entry.
See
for
more
information.
Database
The
Library
Manager
creates
and
maintains
a
database
that
contains
the
following:
v
The
configuration
of
the
3494
Tape
Library
v
Physical
location
information
for
all
the
elements
of
the
3494
Tape
Library
that
the
cartridge
accessor
services
v
The
inventory
of
the
physical
cartridge
volumes
and
logical
volumes
that
a
VTS
manages;
also
information
about
their
use
and
current
status
v
The
status
of
each
3490E,
3590,
or
3592
device
and
virtual
device
As
operations
progress
through
the
library,
the
Library
Manager
updates
the
database
dynamically
on
the
disk
drive
to
reflect
the
current
status
of
the
3494
Tape
Library.
3494
HA1
Option
If
the
3494
HA1
Option
is
installed,
the
right
service
bay
contains
a
second
Library
Manager.
Each
Library
Manager
contains
two
hard
(disk)
drives:
a
primary
disk
and
a
secondary
disk.
Under
normal
operation,
one
Library
Manager
is
the
active
Library
Manager,
and
the
other
Library
Manager
is
the
standby
Library
Manager.
The
active
Library
Manager,
on
its
primary
disk,
creates
and
updates
the
database
dynamically
to
reflect
the
current
status
of
each
3494
Tape
Library.
The
secondary
disk
contains
a
backup
of
the
database,
which
the
Library
Manager
also
updates
dynamically
to
reflect
the
current
status
of
the
3494
Tape
Library.
If
the
active
Library
Manager
fails,
the
standby
Library
Manager
becomes
the
active
Library
Manager
automatically
and
takes
control
of
operations.
A
new
backup
database
is
then
created
on
the
active
Library
Manager’s
secondary
disk.
The
new
active
Library
Manager
runs
in
degraded
mode
until
the
failing
Library
Manager
is
repaired.
This
allows
continued
operation
of
the
3494
Tape
Library.
