How to clear the SBE DIMM memory log on a Dell PowerEdge?

How to clear the SBE DIMM memory log on a Dell PowerEdge?


The single-bit error (SBE) log records memory errors, and each DIMM slot has its own SBE log. If a dual-inline memory module (DIMM) generates errors and the SBE log is incremented or becomes full, and later the DIMM is moved or replaced, the log entries are not automatically cleared. An SBE log that is full will remain full, even after the failing DIMM in that slot is replaced. The SBE log must be cleared manually by command line.

Warning: This command only works for 11G and previous server generations.


Description

SBE log is full.
SBE memory errors were reported.


Solution

The command to clear the memory error count is
dcicfg command=clearmemfailures



The binary dcicfg, needed to launch the command from a shell command, is included in the OpenManage Server Administrator (OMSA) suite.

Note: Most SBE log messages indicate a non-critical issue. If after clearing the memory failures, the same error occurs on the DIMM, then your DIMM or DIMM slot may be faulty and should be replaced. In this case, swap the DIMM with a DIMM in another slot.
If the error follows the DIMM to the new location, then the DIMM is faulty. If the error remains on the same slot, then the slot on the motherboard is faulty.

Note: Clearing the ESM and alert logs alone does not reset the error count on DIMM. After clearing SBE memory log, SBE counter starts automatically.


2 methods are available to execute the command line

Depending of the version of OMSA, you may run differents commands.
