August 3, 20223 yr I had two sata ports on the motherboard fail. I bought a 6 port sata controller card and connected the two cables from the inactive drives to the ports on the new controller card. The server is now doing a rebuild for the two inactive drives. My question is should this be happening since if have not made any changes to the data. I thought that if the server looks for the drive serial number then parity should be valid.
August 3, 20223 yr Community Expert If the drives were disabled when the ports failed they need to be rebuilt, just using a different controller would not necessitate rebuild.
August 3, 20223 yr Author Thanks, for the quick reply. As far as I know, the drives were functioning at the time I noticed they were not being detected. But, I very seldom look at the web GUI so I don't know for sure. However, I did not replace those drives I just changed the sata ports. So, I guess something is wrong. I hope the data on those drives will not be deleted during the parity rebuild.
