Memory DIMM n
Status Scrub failure
detected. (n = DIMM
number)
Error A memory scrub
failure has been
detected.
Note: Each time you install or remove
a DIMM, you must disconnect the
server from the power source; then,
wait 10 seconds before restarting the
server.
1. Check the IBM support website for
an applicable retain tip or firmware
update that applies to this memory
error.
2. Make sure that the DIMMs are
firmly seated and no foreign
material is found in the DIMM
connector. Then, retry with the same
DIMM.
3. If the problem is related to a DIMM,
replace the failing DIMM indicated
by the error LEDs (see “Removing a
memory module” on page 312 and
“Replacing a memory module” on
page 313).
4. If the problem occurs on the same
DIMM connector, swap the affected
DIMMs (as indicated by the error
LEDs on the system board or the
event logs) to a different memory
channel or microprocessor (see
“Replacing a memory module” on
page 313 for memory population).
5. (Trained technician only) If the
problem occurs on the same DIMM
connector, check the DIMM
connector. If the connector contains
any foreign material or is damaged,
replace the system board (see
“Removing the system board” on
page 354 and “Replacing the system
board” on page 359).
