Error A memory scrub
failure has been
detected.
Info DIMM disabled.
6. (Trained technician only) Remove
the affected microprocessor and
check the microprocessor socket
pins for any damaged pins. If a
damage is found, replace the
system board (see "Removing the
system board" on page 258 and
"Installing the system board" on
page 261).
7. (Trained technician only) Swap the
affected microprocessor, if there
are more than one microprocessor
installed. If the problem follows the
microprocessor, replace the
affected microprocessor (see
"Removing the microprocessor and
heat sink" on page 250 and
"Installing a microprocessor and
heat sink" on page 254).
8. (Trained technician only) Replace
the system board (see "Removing
the system board" on page 258
and "Installing the system board"
on page 261).
1. Make sure the DIMM is installed
correctly (see "Installing a memory
module" on page 203).
2. If the DIMM was disabled because
of a memory fault (memory
uncorrectable error or memory
logging limit reached), follow the
suggested actions for that error
event and restart the server.
3. Check the IBM support website for
an applicable retain tip or firmware
update that applies to this memory
event. If no memory fault is
recorded in the logs and no DIMM
connector error LED is lit, you can
re-enable the DIMM through the
Setup utility or the Advanced
Settings Utility (ASU).
