Is there a command to identify which memory slot this error is referring or list all of them, I'm assuming its likely A1 of the 8 slots.

I'm not sure if it starts at channel #1 or channel #0 and might be A2 though (motherboard manual calls A1 channel A).

You are not alone in this problem.  What I would suggest you do is start by googling  CE memory scrubbing error on CPU_SrcID#0_Ha#1_Chan#1_DIMM#0

 

That will get you started.  Apparently, you already have your MB manual for reference.  You could try modifying the search parameters to include your MB spec and see if that gives you more specific help.  Probably, by apply logic and knowledge to your particular situation, some type of pattern will be become obvious.   (Nobody intentionally confused how the information is displayed in the syslog but each manufacturer seems to have their own slot numbering nomenclature ...)

Thanks so a guy here was receiving a channel 0 dimm 0 error also with a supermicro mobo sounds like SM labels start at 0: https://serverfault.com/questions/792225/how-to-find-which-memory-has-ce-error

 

Looks like its likely slot A2 then, ill give that shot.

What is the steps to clear that hardware error out of the logs so I can see if it comes back? (I updated unraid versions previously and it cleared it but didn't reoccur til a week or so later).

Restarting apparently clears the errors associated, or at least there are no errors now after replacing the ram in A1/A2.
