DHS EMP HSP INI ONL PRC RBL RDY SBY SHS drive. Before you replace the drive, ensure that: 1. All cables are connected correctly to the backplane and to the hard disk drive. Also, check to ensure that all cables inside the server are connected correctly. 2. The hot-swap drive tray is seated properly in the drive bay. 3. See "Symptom-to-FRU index" on page 264. A drive enters the Defunct Hot-spare (DHS) state if: 1. A defunct (DDD) drive has been rebuilt to another drive, such as a hot-spare drive. 2. A hot-spare (HSP) or standby hot-spare (SHS) drive fails to respond to commands from the ServeRAID controller. No device is present in the bay. This state appears as dashes (- - -) on the ServeRAID configuration screen, or as a blank space on the Administration and Monitor utility screen. A hot-spare (HSP) drive is a hard disk drive that is defined for automatic use when a similar drive fails. (See "Defining hot-spare drives" on page 111 for more information.) The INI represents the initiator for the ServeRAID controller. The drive is online (ONL). It is functioning properly and is part of an array. The device is a generic SCSI controller (for example, a hot-swap backplane that has onboard systems-management support). The drive is being rebuilt. (See "Understanding the drive rebuild process" on page 131 for more information.) The ServeRAID controller recognizes a ready (RDY) drive as being available for definition. The ready drive state changes to empty (EMP) when the drive is physically removed from the bay. A standby (SBY) drive is a hard disk drive that the ServeRAID controller has spun down. A standby hot-spare (SHS) is a hot-spare drive that the ServeRAID controller has spun down. If an online (ONL) drive becomes defunct and no suitable hot-spare drive is available, a standby hot-spare of the appropriate size automatically spins up, and enters the rebuild (RBL) state.
