Turned out to be a faulty SAS cable! Drives were working fine, no issues reported, but replacing the SAS cable from RAID controller to backplane resolved the issue. Weird.
Hi all, I have an R410 that on both HDD's (it has 2), neither power LED is working on the caddy. The status LED is working fine. I wouldn't have though both caddies have a problem specifically with the Power LED showing, have I missed a setting somewhere that turns them off? Thanks in advance.
Dell R410 No HDD Power LED (Status LED OK)
