Relationship
between
Operational
Modes
and
States
When
you
request
an
operational
mode
or
state
change,
the
3494
Tape
Library
must
perform
some
steps
before
it
completes
the
change.
During
this
transition
period,
the
immediate
mode
or
state
of
the
3494
Tape
Library
is
mode
pending
or
state
pending
.
For
example,
if
the
3494
Tape
Library
is
in
the
Online
state
and
you
make
a
request
to
enter
the
Offline
state,
the
immediate
operational
state
is
Offline
Pending
.
The
System
Summary
window
on
the
Library
Manager
console
indicates
whether
the
mode
or
state
is
pending.
Sometimes
the
change
between
the
modes
and
the
states
occurs
quickly,
and
the
pending
status
is
displayed
briefly.
Operational
Mode
Transitions
The
3494
Tape
Library
is
in
only
one
operational
mode
at
any
one
time.
When
the
Library
Manager
requests
a
change
in
operational
mode,
it
displays
a
window
that
allows
you
to
confirm
the
mode
change
request.
Note:
If
the
3494
HA1
Option
is
installed,
this
applies
to
the
active
Library
Manager.
Pause
Mode
to
Auto
Mode
You
can
use
either
the
operator
panel
(see
or
the
Library
Manager
to
request
a
change
to
Auto
mode.
Either
way
you
generate
the
request,
the
Library
Manager
checks
the
status
of
the
3494
Tape
Library.
When
you
use
the
Library
Manager
to
request
a
change
from
Pause
mode
to
Auto
mode,
the
following
actions
occur:
1.
The
Library
Manager
checks
the
status
of
the
interface
to
the
cartridge
accessor.
If
it
is
not
available,
a
window
indicates
that
the
cartridge
accessor
interface
is
unavailable.
You
can
cancel
the
request
to
change
to
Auto
mode.
2.
The
Library
Manager
checks
the
cartridge
accessor
status.
If
it
is
not
available
because
of
a
previous
failure,
the
Library
Manager
tests
the
accessor
to
determine
if
it
can
be
made
available.
If
it
can
be
made
available,
the
Library
Manager
attempts
the
transition
to
Auto
mode.
If
the
Library
Manager
detects
a
hardware
problem,
the
3494
Tape
Library
returns
to
Pause
mode,
and
a
window
indicates
that
the
cartridge
accessor
is
unavailable.
You
can
cancel
the
request
to
change
to
Auto
mode.
