The
following
information
pertains
to
console
takeover
and
recovery:
In
V5R4
and
later
releases,
there
is
a
special
set
of
functions
known
as
console
take
over
and
recovery,
that
allows
a
LAN-connected
Operations
Console
to
take
control
from
another
console
device.
Use
the
following
information
to
help
determine
what
console
devices
are
best
for
your
work
environment
and
how
to
deploy
these
devices
to
take
advantage
of
the
new
functions.
v
Takeover
is
the
process
used
for
a
LAN-connected
console
device
to
take
control
from
the
current
console
device.
The
user
signed
on
to
the
PC
that
wishes
to
take
control
requires
special
authority
and
is
initiating
the
takeover
from
a
new
menu.
This
takeover
function
is
not
used
for
directly
attached
consoles.
v
Recovery
is
the
process
of
regaining
control
of
the
job
running
on
the
console
after
a
problem
with
the
console
was
encountered.
The
recovery
process
may
be
to
the
same
console
device
or
a
different
console
device
and
may
be
facilitated
by
additional
work
to
enable
a
device
using
a
different
connectivity.
The
exception
is
twinaxial
console
which
does
not
use
the
same
type
of
5250
emulation
and
thus
cannot
recover
the
console
without
data
loss.
When
the
takeover
option
is
enabled
and
the
device
is
properly
connected,
each
console
capable
device
running
5250
emulation,
regardless
of
connectivity,
will
be
presented
a
screen
of
data
regardless
of
whether
or
not
it
is
the
active
console.
In
V5R3
and
later
releases,
more
than
one
device
will
have
data
on
the
screen
after
the
console
has
been
established.
There
will
be
no
more
blank
console
screens
showing
Disconnected
when
initially
connecting
a
device.
The
new
function
now
allows
the
job
at
the
console
to
be
transferred
to
another
device
without
causing
loss
of
data.
This
function
is
accomplished
by
suspending
the
data
stream
to
a
console
that
loses
a
connection
or
is
being
taken
over,
save
further
data
and
then
send
that
data
to
the
next
device
to
become
the
console,
even
if
the
device
is
the
same
former
console.
Recoverability
is
essentially
taking
over
the
console
from
the
same
or
different
qualified
device
regardless
of
what
the
former
console
was
doing.
The
following
information
pertains
to
independent
and
primary
partitions:
v
Console
supporting
hardware
may
be
required
to
be
located
in
specific
slot
locations,
based
on
model.
v
Multiple
IOPs
capable
of
supporting
a
console
workstation
can
interfere
with
the
selection
of
the
desired
LAN
adapter.
Consider
the
following:
–
Having
a
second
IOP
on
the
bus
before
your
intended
console
adapter
card,
when
the
first
IOP
contains
a
twinaxial
adapter
card,
may
fail
to
provide
a
LAN-connected
console.
For
example,
a
model
890
uses
eligible
card
locations
C04,
and
C06
through
C10
and
if
an
IOP
were
placed
in
C08
and
a
twinaxial
adapter
preceded
this
IOP
on
the
bus
then
the
LAN
adapter
card
located
at
C09
or
C10
will
fail
to
provide
a
LAN-connected
console.
The
LAN
adapter
card
must
be
in
a
location
preceding
the
second
IOP,
such
as
C06
or
C07.
–
Typically,
the
card
location
used
for
Operations
Console
directly
attached
configurations,
commonly
referred
to
as
the
Electronic
Customer
Support
(ECS)
slot,
is
located
close
to
the
beginning
of
the
bus.
When
the
card
location
is
a
low
number,
for
example
C02,
then
C03
is
further
from
the
beginning
of
the
bus
than
C02.
When
the
card
location
is
a
high
number,
for
example
C07,
then
C06
is
further
from
the
beginning
of
the
bus
than
C07.
There
may
be
exceptions
to
this
numbering
scheme
based
on
specific
models
and
expansion
units.
Contact
your
service
representative
if
you
have
questions
about
the
placement
of
the
ECS.
The
following
information
pertains
to
a
multi-partitioned
environment:
v
If
you
plan
to
use
Operations
Console
as
your
primary
console
or
as
a
backup
console,
you
must
tag
the
IOP
to
support
the
primary
console
and
Electronic
Customer
Support
(slot),
even
if
you
do
not
plan
to
use
Electronic
Customer
Support.
For
example,
if
you
are
planning
to
use
Operations
Console
on
a
direct
connection,
you
must
tag
an
IOP
with
the
console
tag
and
the
ECS
tag.
These
steps
are
also
necessary
if
you
are
planning
to
use
Operations
Console
with
a
LAN
connection.
v
When
more
than
one
console
adapter
is
available
for
a
single
IOP,
the
adapter
with
the
lowest
bus
address
will
be
chosen
for
use
by
Operations
Console.
For
example,
you
tag
an
IOP
that
has
two
LAN
Operations
Console
