Message Description Action
W.58001 [W.58001] The PFA Threshold
limit (correctable error logging
limit) has been exceeded on
DIMM number % at address %.
MC5 Status contains % and
MC5 Misc contains %. DIMM PFA Threshold
Exceeded. 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.
Swap the affected DIMMs (as
indicated by the error LEDs on
the system board or the event
logs) to a different memory
channel (see “Installing a memory
module” on page 62 for memory
population sequence).
3. If the error still occurs on the
same DIMM, replace the affected
DIMM.
4. If the problem occurs on the same
DIMM connector, swap other
DIMMs (in the same memory
channel) to a different memory
channel or microprocessor (see
“Installing a memory module” on
page 62 for memory population
sequence). If the problem follows
a moved DIMM to a different
memory channel, replace the
affected DIMM.
5. (Trained technician only) If the
problem occurs on the same
DIMM connector, check the
DIMM connector. Remove any
foreign material on the DIMM
connector, if found. If the
connector is damaged, replace the
system board.
6. (Trained technician only) Remove
the affected microprocessor and
check the microprocessor socket
pins for any damaged pins. If a
damage is found or the
microprocessor is an upgrade
part, replace the system board.
7. (Trained technician only) Replace
the affected microprocessor (see
“Removing a microprocessor and
heat sink” on page 416 and
“Replacing a microprocessor and
heat sink” on page 418).
8. (Trained technician only) Replace
the system board.
