My server has 11 drives connected ATM with more to come. These are connected in a variety of ways - 2 SCSI drives, 6 SATA drives plugged directly into the mobo, and 3 via port multipliers. All of these drives are in various softRAID arrays. I'd like to be able to identify a specific drive via software, so that when a drive is overheating or failing I can pull just that drive, instead of going through the 'Let's pull this one and see if that's right' routine. Long ago I had a hardware RAID controller that could do just that. You could tell it to id a specific drive and it would flash that LED. Is there any way to do that? --Yan
