Use
this
procedure
to
determine
if
the
multi-adapter
bridge
is
failing
when
the
symbolic
FRU
PIOCARD
is
in
the
failing
item
list,
with
other
failing
items
that
have
a
multi-adapter
bridge
as
a
component.
The
procedure
will
start
with
the
failing
item
list
for
the
SRC
that
sent
you
here.
It
will
determine
if
PIOCARD
should
be
removed
from
the
failing
item
list
that
you
are
working
in.
Use
the
Service
Action
Log
(SAL)
to
check
for
other
errors
under
the
same
multi-adapter
bridge
using
the
following
steps:
1.
Were
you
able
to
obtain
a
location
for
the
PIOCARD
FRU
from
the
SAL?
v
No
:
Find
the
SRC
in
the
SAL
and
record
the
Direct
Select
Address
(DSA)
in
word
7.
See
to
find
the
DSA
in
the
SRC.
Then,
continue
with
the
next
step.
v
Yes
:
Go
to
step
5
(See
page
2.
Record
the
Bus
number
(
BBBB
part)
of
the
DSA
and
the
Multi-adapter
bridge
number
of
the
DSA.
The
multi-adapter
bridge
number
is
the
first
character
of
the
card
identifier
part
(
Cc
)
in
the
DSA.
See
to
find
the
DSA
in
the
SRC.
3.
Go
to
to
determine
the
location
of
the
PCI
I/O
Card
in
the
failing
item
list.
Return
here
and
continue
with
the
next
step.
4.
Using
the
card
position
table
for
the
frame
or
I/O
tower
type
that
you
recorded
in
Determine
which
of
the
card
positions
within
the
frame
or
I/O
tower
are
controlled
by
the
same
multi-adapter
bridge
that
is
controlling
the
PCI
I/O
card
for
which
you
determined
the
location
in
step
3
(See
page
See
in
the
Bus-PIP
overview.
A
card
position
is
controlled
by
the
same
multi-adapter
bridge
if
it
has
the
same
bus
number
and
multi-adapter
bridge
number
as
the
PCI
I/O
Card
that
you
located
in
step
3
(See
page
Record
the
card
position
and
the
DSA
from
the
card
position
table
for
each
card
position
that
is
controlled
by
the
same
multi-adapter
bridge.

Look
for
other
failures

that
are

6.
Are
there

that
are

FRU?
v
No
:
Use
the
failing
item
list
that
you
were
using
when
you
started
this
procedure.
v
Yes
:
The
multi-adapter
bridge
is
failing.
Remove

Isolate
to
failing
multi-adapter
bridge
resource
Use
this
procedure
to
isolate
a
failing
I/O
processor
or
I/O
adapter
under
a
multi-adapter
bridge.
The
procedure
will
iterate
through
each
IOP
under
the
multi-adapter
bridge,
powering
each
one
off,
and
then
resetting
the
multi-adapter
bridge.
This
process
will
be
repeated
until
the
failing
part
is
isolated.

Does
the

v
Yes
:
Go
to
the
SST/DST
display
in
the
partition
which
reported
the
problem.
Use
STRSST
if
OS/400
is
running,
use

not
work,
or
IPL
