v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 4, "Parts listing, Types 7871 and 1949," on page 41 to determine which components are customer
replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
Trained service technician.
Error code Description
00580A5 Mirror failover detected.
0058001 PFA threshold exceeded.
Action
Information only. Memory redundancy has been lost.
Check the event log for uncorrected DIMM failure
events (see "Error logs" on page 99).
1. Refer to TIP H21455 for minimum code level.
2. Check the IBM support website for an applicable
retain tip or firmware update that applies to this
memory error.
3. 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 "Installing a memory
module" on page 64 for memory population
sequence).
4. If the error still occurs on the same DIMM,
replace the affected DIMM.
5. (Trained service technician only) If the problem
occurs on the same DIMM connector, check the
DIMM connector. If the connector is damaged,
replace the system-board assembly (see
"Removing the system-board assembly" on page
94 and "Installing the system-board assembly" on
page 95).
6. (Trained service 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 assembly (see "Removing the
system-board assembly" on page 94 and
"Installing the system-board assembly" on page
95).
7. (Trained Service technician only) Replace the
affected microprocessor (See "Removing a
microprocessor and heat sink" on page 85 and
"Installing a microprocessor and heat sink" on
page 88).
