Drive State Defunct Empty Hot Spare Online Rebuilding Ready Standby Standby Hot Spare Meaning A physical hard disk drive in the Online, Hot-Spare, or Rebuild state has become defunct. It does not respond to commands, which means that the ServeRAID controller cannot communicate properly with the drive. A hard disk drive in the Defunct state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that: 1. All cables are connected properly to the server backplane and to the hard disk drive. Also, check to ensure that all cables inside the server are connected properly. 2. The hot-swap drive trays are seated properly in the drive bay. 3. The termination for each device on the SCSI channel is set properly. 4. Each device on the SCSI channel has its own, unique SCSI ID. If the hard disk drive still does not function after you perform these steps, replace the drive. No device is present in the bay. A Hot-Spare drive is a hard disk drive that is defined for automatic use when a similar drive fails. The drive is Online. It is functioning properly and is part of an array. The drive is being rebuilt. For more information on rebuilding a drive, refer to "Rebuilding a defunct drive" on page 157. The ServeRAID controller recognizes a Ready drive as being available for definition. A Standby drive is a hard disk drive that the ServeRAID controller has spun down. A Standby Hot Spare is a Hot-Spare drive that the ServeRAID controller has spun down. If an Online drive becomes Defunct and no suitable Hot-Spare drive is available, a Standby Hot-Spare drive of the appropriate size automatically spins up, and enters the Rebuild state.
