Physical Device States

Physical Device States

Descriptions of the physical device states, which appear in the Array/Bay selection list, are as follows:

State	Meaning
CDR	A CD-ROM drive is installed.
DDD	The physical hard disk drive is defunct (DDD). A drive in the Online
	(ONL) or Rebuild (RBL) state has become defunct (DDD). It does not
	respond to commands, which means that the ServeRAID controller cannot
	communicate properly with the drive.
	A hard disk drive in the DDD state does not necessarily mean that you
	need to replace the 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'.
DHS	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.
EMP	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.
HSP	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' for more information.)
INI	The INI represents the initiator for the ServeRAID controller.
ONL	The drive is online (ONL). It is functioning properly and is part of an array.
PRC	The device is a generic SCSI controller (for example, a hot-swap backplane
	that has onboard systems-management support).
RBL	The drive is being rebuilt. (See 'Understanding the Drive Rebuild Process'
	for more information.)
RDY	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.
SBY	A standby (SBY) drive is a hard disk drive that the ServeRAID controller
	has spun down.
SHS	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.
TAP	A tape drive is installed.

Logical Drive States:

Descriptions of the logical drive states, which appear in the Logical Drive list, are as follows:

State	Meaning
CRM	A logical drive undergoing a logical-drive migration (LDM) is in the
	critical state.
CRS	The ServeRAID controller uses this reserved state during a logical-drive
	migration (LDM).
CRT	A RAID level 1 or 5 logical drive that contains a defunct physical drive
	is in the critical state. A critical (CRT) logical drive is accessible,
	despite a physical drive failure.
FRE	The drive is in a free (FRE) state. It is not defined.
LDM	The logical drive is undergoing a logical-drive migration (LDM), that is,
	a change in RAID levels, a change in logical drive size, or an increase in free space.
OFL	The logical drive is offline (OFL) and not accessible. This state occurs if one or more
	physical drives in a RAID level 0 logical drive are defunct. This state also occurs
	when two or more physical drives in a RAID level 1 or RAID level 5 logical drive are defunct.
OKY	The drive is okay (OKY). It is in a good, functional state.
SYS	The ServeRAID controller uses this reserved state during logical-drive migration (LDM).
	If the state of the logical drive is critical (CRT), you must replace and rebuild the
	defunct drive. See 'Understanding the Drive Rebuild Process' for more information.
