5.6.5 Drive I/O Faults

Diagnose and rectify drive I/O faults depending on the symptoms.
Issue 20 (2020-09-25)
Handling Procedure
1. Install the faulty DIMM in
different channels and use
FusionServer Tools Toolkit
orSmart Provisioning
the DIMM.
● If the error is caused by the
DIMM, replace the DIMM.
● If the error is caused by the
DIMM slot, check the
DIMM connector. If the
connector is damaged,
replace the mainboard or
memory board.
2. Remove the CPU connected to
the faulty DIMM channel, and
check whether the CPU socket
pins are damaged.
● If yes, replace the
mainboard.
● If no, go to 3.
3. Replace the CPU connected to
the faulty DIMM channel.
NO TE

5 Diagnosing and Rectifying Faults
Quick Recovery Method
1. Switch the position of a
DIMM you suspect to be
faulty and a DIMM which is
to test functioning correctly. Then,
determine whether the fault
is caused by the DIMM or
DIMM slot.
● If the fault is caused by
the DIMM you suspect to
be faulty, replace the
DIMM.
● If the fault is caused by
the DIMM slot, change
the CPU with a normal
one. If the problem is
caused by the CPU,
replace the CPU.
Otherwise, replace the
mainboard or memory
board.
2. If the preceding steps do
not reproduce the fault, use
FusionServer Tools Toolkit
or Smart Provisioning
perform memory pressure
tests. If the fault is
reproduced, perform 1.
Otherwise, contact Huawei
technical support.
