203w 0xyz Remote I/O (RIO) configuration
warning.
This code indicates that an 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 drawers 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 drawers 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 CEC drawer according to the
following table:
y = Nearest RIO Port
1 = 0
2 = 1
v
z = B, indicates a missing return
line from the I/O drawer to the
CEC drawer.
v z = C, indicates a missing link
between two I/O drawers.
v
z = E, indicates an I/O drawer was
found connected to RIO port 3 with
no return to the CEC drawer, and
no I/O drawer was found
connected to RIO port 2. In this
case, the I/O connected to RIO
port 3 is removed from the
configuration because the cause of
the error and the proper location of
the I/O cannot be determined.
1. Check the RIO cables
2. Go to “MAP 1540: Minimum
Configuration” on page 113.
