[Linux-PowerEdge] Clearing memory errors

The error "should" clear itself after the faulty memory has been replaced but sometimes this is not the case.

Running this command will clear the error:
dcicfg command=clearmemfailures

Subject: [Linux-PowerEdge] Clearing memory errors

We recently had an R720 exceed memory errors for a DIMM (16GB).  We got a replacement and swapped it in.  During which time the power cables were removed and the power button held down for 20+ seconds.

However, on reboot, although the DRAC GUI says all is well, we see this with
OMSA:

Any ideas how to clear this, please?
