Note:
You
can
view
component

from
the
Specialist
(see
The
Library
Manager
keeps
track
of
the
components
that
are
available
so
that
it
can
make
the
best
use
of
the
available
hardware
when
processing
commands.
When
a
component
fails,
the
component
is
marked
unavailable
for
use
automatically.
The
Library
Manager
does
not
use
the
component
until
it
is
marked
available
through
the
Service
menu
on
the
Library
Manager
console.
You
can
display
the
availability
status
of
all
the
3494
Tape
Library
components
on
the
Library
Manager
console.
Availability
information
is
kept
in
the
Library
Manager
database
so
that
it
is
not
lost
if
the
Library
Manager
is
shut
down.
Drives
can
be
marked
on
the
Library
Manager
as
available
or
unavailable.
If
a
drive
is
available,
it
is
available
to
the
cartridge
accessor.
If
the
drive
is
marked
unavailable,
the
drive
is
not
available
to
the
cartridge
accessor.
Note:
Device
availability
or
unavailability
is
independent
of
the
drive
status
(online
or
offline)
with
the
host.
A
drive
is
marked
unavailable
when
something
prevents
the
cartridge
accessor
from
going
to
that
drive
(for
example,
when
the
drive
is
being
serviced).
Even
if
no
host
requests
are
made
for
the
drive,
the
Library
Manager
may
try
to
clean
a
drive
if
it
is
available.
Device
availability
is
not
checked
when
host
requests
are
received
and
validated.
It
is
not
checked
because
the
drive
availability
can
change
between
the
time
the
command
is
accepted
and
the
time
the
request
is
executed.
If
a
host
request
is
accepted
and
the
required
drive
is
marked
as
unavailable
when
it
is
time
to
execute
the
request,
the
request
fails.
Conversely,
if
the
required
drive
is
unavailable
at
request
acceptance
but
is
made
available
before
the
request
executes,
the
request
completes
normally.
