The failed disk is either /dev/sdd or /dev/sde, but since both disks here is the same make and model it is hard for me to determine which serial number under /dev/disk/by-id is the correct one to remove.
Now the question is: dmesg refers to ata5.00 , which one is correct? lsscsi or /dev/disk-by/path/ or (more likely) are both correct. How to determine which disk is actually failing?
EDIT: This question is about finding out what ataX.XX in dmesg refers to what /dev/sdX
