State
to
Initialization
Complete
State
After
the
Library
Manager
starts
the
main
process
of
the
Library
Manager
application,
the
3494
Tape
Library
enters
the
Initialization

change.
Offline
State
to
Online
State
Either
you
or
the
Library
Manager
can
initiate
the
request
to
enter
the
Online
state.
In
either
case,
the
following
actions
occur
during
the
transition:
1.
The
Library
Manager
examines
the
database
to
determine
if
both
the
teach
and
the
inventory
operations
have
completed.
The
3494
Tape
Library
cannot
enter
the
Online
state
unless
they
have
completed.
2.
The
Library
Manager
examines
the
status
of
the
interfaces
to
the
tape
drives
and
host
systems
to
determine
whether
any
interfaces
are
initialized
with
the
Library
Manager.
If
at
least
one
of
the
tape
drive
interfaces
is
initialized
and
the
associated
controller
is
Online
to
the
Library
Manager,
the
3494
Tape
Library
enters
the
Online
state
and
notifies
all
attached
hosts.
If
no
interfaces
are
initialized,
the
3494
Tape
Library
enters
the
Online
state
but
does
not
send
a
notification.
3.
If
a
VTS
is
installed,
the
Library
Manager
checks
for
defined
“Fast
Ready”
categories.
If
it
finds
none,
a
message
stating
that
“Fast
Ready”
categories
should
be
defined
is
displayed
for
one
minute
or
until
you
select
OK
.
Notify
your
system
administrator
if
you
see
this
message.
Online
State
to
Offline
State
You
initiate
a
request
to
enter
the
Offline
state.
After
you
request
it,
the
transition
must
complete
before
you
can
request
a
transition
to
the
Online
state.
The
following
actions
occur
during
the
change
to
the
Offline
state:
1.
The
Library
Manager
sends
a
message
to
all
attached
hosts
indicating
that
the
3494
Tape
Library
is
entering
the
Offline
state.
The
controllers,
VTSs,
and
the
Library
Manager
will
fail
any
later
host
requests
for
3494
Tape
Library
functions.
2.
The
3494
Tape
Library
processes
all
host
requests
that
the
Library
Manager
accepted
and
queued
before
the
request
to
enter
the
Offline
state.
The
Library
Manager
provides
responses
to
the
requesting
host
as
appropriate.
3.
The
Library
Manager
completes
all
internal
commands
that
were
queued
before
the
request
to
enter
the
Offline
state.
If
it
detects
errors,
it
sends
appropriate
messages
to
all
attached
hosts.
4.
After
the
Library
Manager
completes
all
queued
commands
and
sends
responses,
the
3494
Tape
Library
enters
the
Offline
state.
Note:
1.
The
change
from
the
Online
to
the
Offline
state
can
take
more
than
ten
minutes
if
a
High-Capacity
Output
operation
started
before
the
request
to
go
to
the
Offline
state.
The
3494
Tape
Library
needs
this
time
to
move
the
cartridges
to
the
High-Capacity
Output
Facility
from
the
storage
cells.
If
a
High-Capacity
operation
is
in
progress,
