I rebooted my server to update to FN 11.3-U3.1, and got an email:
I logged into IPMI, and found the System Event Log had an entry:
Failing DIMM: DIMM location. (Correctable memory component found) (DIMMC1)
There were six similar errors over the last six months in the log, all for slot C1, but this is the first one for which I received an email.
I shutdown the server and swapped the DIMMs between slots C1 and D1, to attempt to determine if the issue is bad DIMM or a bad slot. Or maybe reseating the DIMM would correct the problem.
What does this error mean? Did ECC find and correct a one bit error?
Server Details:
Supermicro X10SRH-cF
E5 1650-v4 CPU
96 GB ECC RAM
8x 4TB WD Red in RAIDZ2 + 8x 4TB WD Red in RAIDZ2 as local backup pool
Norco RPC-4224 chassis.
Code:
