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 off the system
and power it on 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. Check RIO cable connections
2. Clear NVRAM and retry
3. Check for system firmware
update
4. Replace primary I/O drawer
