Bus
problem
Symptom
What
you
should
do:
The
system
has
detected
a
bus
problem.
An
SRC
of
the
form
B600
69xx
will
be
displayed
on
the
Control
Panel.
Bus
errors
will
not
prevent
a
system
from
completing
an
IPL,
though
bus
errors
are
logged
during
an
IPL.
Though
it
is
possible
for
a
bus
error
to
bring
a
system
or
partition
down,
most
of
the
time
the
system
or
partition
will
be
functioning
and
the
error
will
be
logged
in
the
Service
Action
Log.
If
the
system
shows
an
SRC
in
the
Service
Action
Log,
look
at
the
failing
items
identified
in
the
Service
Action
Log
view.
If
possible
failing
hardware
can
be
identified,
the
Service
Action
Log
will
list
hardware
FRUs
to
be
replaced.
If
hardware
FRUs
can
not
be
identified,
the
Service
Action
Log
will
list
procedures
designed
to
isolate
failing
hardware.
Perform
any
symbolic
FRUs
or
Bus
problem
isolation
procedures
(Bus
PIPs)
listed
in
the
Service
Action
Log.
To
replace
hardware,
go
to
for
the
system
or
tower
on
which
you
are
working.
If
a
Service
Action
Log
is
not
available,
use
the
SRC
on
the
control
panel
and
go
to
the
appropriate
System
reference
code
table.
