Well I haven't used a J4500, but when we had an x4500 (Thumper) on loan they had Solaris pretty well integrated with the hardware. When a disk failed, I used cfgadm to offline it and as soon as I did that a bright blue "Ready to Remove" LED lit up on the drive tray of the faulty disk, right next to the handle you need to lift to remove the drive.
There's also a bright red "Fault" LED as well as the standard green "OK" LED, so spotting failed drives really should be a piece of cake. Certainly in my tests, so long as you followed the procedure in the manual it really is impossible to get the wrong drive.
