Error Code Description

20FB 0xxx Permanent addressing to map SPCN
addresses to match RIO addresses.
Note: 20FB 0xxx error codes will
cause the system to hang.

SPCN configuration table in NVRAM
Action/ Possible Failing FRU
Values normally found in non-volatile
storage that point to the location of
an operating system were not found.
This can happen for two reasons;
either your installed operating system
does not support storing the values
or some event occurred that caused
the system to lose non-volatile
storage information (drainage or
replacement of the battery). If you
are running AIX, this information can
be reconstructed by running the
bootlist command specifying the
device that the operating system is
installed on. Refer to your AIX
documentation for the exact syntax
and usage of the bootlist command.
To boot the operating system so that
the above mentioned values can be
reconstructed, power the system
down and power it back up again.
This should cause the system to look
for the operating system in the
devices contained in the custom boot
list or in the default boot list,
depending on the condition of the
system. If this is not successful, use
the System Management Services
menus to modify the boot sequence
(also known as boot list) to include
devices that are known to contain a
copy of the operating system. For
example, select a hard disk known to
have a copy of the operating system
as the first and only device in the
boot sequence (boot list) and attempt
to boot again.
1. Clear NVRAM and retry
2. Check for system firmware
update
3. Replace the system board. (See
