adapters
installed.
The
system
will
use
the
first
adapter
found
on
the
bus.
However,
during
an
IPL
the
first
adapter
may
not
be
ready
in
time
and
the
system
could
select
the
second
adapter.
This
could
prevent
the
console
from
starting
immediately
or
you
might
not
be
able
to
use
that
resource
for
your
intended
purposes.
It
is
recommended
that
you
install
only
one
console-capable
adapter
that
matches
your
configurations
for
a
single
IOP.
This
situation
also
will
affect
asynchronous
adapters
used
by
a
local
console
directly
attached
to
the
system.
v
The
term
alternate
console
is
referring
to
a
twinaxial
console
type
located
in
another
IOP
tagged
as
the
alternate
console.
Operations
Console
and
HMC
type
consoles
do
not
use
resources
tagged
as
the
alternate
console.
Note:
Tagging
the
same
IOP
as
both
the
primary
console
and
the
alternate
console
may
result
in
the
inability
to
select
a
console.
If
you
have
a
twinaxial
adapter
in
the
same
IOP
as
your
primary
console’s
adapter,
consider
the
twinaxial
adapter
to
be
a
backup
console,
not
an
alternate
console.
You
only
have
to
change
the
console
type
to
take
advantage
of
the
twinaxial
adapter
for
the
console.

many

consider
the
console
in
their
plans.

Considerations
for
a
backup
console
v
The
adapter
location
is
fixed,
or
at
least
limited,
for
independent
systems
or
primary
partitions.
Based
on
your
system’s
hardware
requirements,
you
might
have
limited
choices
of
console
types.
Try
to
accommodate
at
least
one
additional
console
type,
if
possible.
v
Consider
using
the
take
over
and
recovery
option
as
part
of
your
backup
console
strategy.
However,
the
hardware
used
for
the
new
console
type
must
exist
and
be
available
at
the
time
of
recovery.
v
If
you
are
working
in
a
partitioned
environment,
consider:
–
In
a
logical
partition
environment,
the
term
alternate
console
refers
to
the
twinaxial
console
type
located
in
another
input/output
processor
(IOP)
that
is
tagged
as
the
alternate
console.
If
a
failure
of
the
primary
console
(twinaxial
only)
is
detected,
the
system
automatically
tries
the
alternate
console’s
IOP.
This
function
gives
you
another
level
of
protection.
Tagging
a
single
IOP
as
both
the
primary
console
and
the
alternate
console
can
result
in
errors
when
selecting
a
console.
Further
isolation
can
be
planned
by
placing
the
alternate
console
IOP
on
a
different
bus
so
that
failures
of
the
primary
console’s
bus
cannot
prevent
a
console
from
being
available.
–
Models
270
and
8xx
are
tagged
for
a
console
type
only
at
the
IOP
level.
Tagging
an
IOP
that
has
two
alike
console
adapters
reporting
to
it,
for
example
two
2849s
or
two
2771s,
for
the
same
IOP
can
sometimes
make
it
difficult
to
determine,
in
advance,
which
adapter
will
be
used
for
the
console.
When
tagging
the
IOP,
be
sure
that
it
only
has
one
console-capable
adapter
per
connectivity.
For
example,
only
one
2849
and
one
2771.
Each
adapter
can
support
a
different
console
type
but
only
one
adapter
type
should
be
present.
The
lowest
addressed
adapter
on
the
bus
is
attempted
first.
But
if
that
adapter
is
slow
in
reporting
to
the
system,
another
adapter
might
get
selected
instead,
when
two
adapters
of
the
same
connectivity
are
present.
Another
example
of
this
might
be
that
the
IOP
has
both
a
2838
and
a
2849
Ethernet
adapter
reporting
to
it.
They
are
different
adapters
but
have
the
same
connectivity
for
the
console.
