Physical Drive State Descriptions

Physical Drive State Descriptions

The following table provides descriptions of the valid physical drive states.

Drive State	Meaning
Defunct	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.
Empty	No device is present in the bay.
Hot Spare	A Hot-Spare drive is a hard disk drive that is defined for automatic
	use when a similar drive fails.
Online	The drive is Online. It is functioning properly and is part of an array.
Rebuilding	The drive is being rebuilt.
	For more information on rebuilding a drive, refer to
	'Rebuilding a Defunct Drive'.
Ready	The ServeRAID controller recognizes a Ready drive as being available for
	definition.
Standby	A Standby drive is a hard disk drive that the ServeRAID controller has
	spun down.
Standby	A Standby Hot Spare is a Hot-Spare drive that the ServeRAID controller
Hot Spare	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.
