Error Code Description Action/
Possible Failing FRU
203w 0xyz Remote I/O (RIO) configuration warning.
This code indicates that a RIO configuration
was detected that does not result in complete
loops. The system continues to boot, however
performance or recovery capability may be
reduced. In some cases, the problem may
result in missing I/O. Remote I/O subsystems
are connected in loops. Use the letters w, y,
and z in the error code to isolate the location
of the open loop. Check RIO cables for loose
connections, and verify power on the I/O
subsystems by the presence of fan motion.
The following numbers may be used to help
isolate the failing component.
v
w = loop number, this is either 0 or 1 in a
system with 2 RIO loops.
v
x = Always 0.
v
y is either 1 or 2 on a system with 2 loops.
y indicates the nearest associated RIO port
number on the processor subsystem
according to the following table:
y = Nearest RIO Port
1 = 0
2 = 1
3 = 2
4 = 3
v
z = B, indicates a missing return line from
the I/O subsystem to the processor
subsystem.
v z = C, indicates a missing link between two
I/O subsystems.
v
z = E, indicates an I/O subsystem was
found connected to RIO port 3 with no
return to the processor subsystem, and no
I/O subsystem was found connected to RIO
port 2. In this case, the I/O connected to
RIO port 3 is removed from the
configuration since the cause of the error
and the proper location of the I/O cannot
be determined.
