I have both the Activity and Attention LED's off in one of the disks - NetApp DS212C disk shelf (FAS2520). The disk is NetApp 108-00270+B0 - 2TB 7.2K RPM 64MB Cache SATA 3.5" encased in a NetApp 111-00734+C0 - 2TB Hard Drive Caddy with NetApp P003464-01a - Emulex SATA - SAS Server Interposer Board.
What could be wrong? The disk or the carrier / caddy.
