\Device\AFA0 related error

I'm getting the same series of errors on a PowerEdge with the PERC 3/Di controller. They're only appearing in the Windows Event Log, they're not appearing in the Dell OpenManage Array Manager console at all.

Our initial impression is that it's a hard disk going bad, but that theory isn't supported by the Array Manager. Any other ideas?

Hi,

 

since a few days, every night around 2AM my poweredge 2450 server registers the following warnings in the Windows 2000 event log:

It appears some kind of bad block detection system. What I'd like to understand is which disk is affected. The server has a PERC3D/i RAID controller with 4 disks connected to it, in RAID1 (mirror). Basically an "Array Group 0" with a "Raid 1 container 0" and "Raid 1 container 1" where each container is made up of 2 disks.

 

I'm asking this here cause no warning or error message is reported anywhere else but in the windows' event log (diagnostics all ok, open manage server administrator all ok, etc...)

 

Thanks for any help you can give me.
