			Array Drive Module Status Descriptions
Table A-5. Array Drive Module Status Descriptions
Drive Module Status	Status Code		Meaning/Description
			Production Partition
Production: Active	P.A (PA)	Drive is active.
		Drive is inactive and marked as broken. After its data is moved to
Production: Broken	P.B (PB)	a spare, broken drive is removed from Production partition and
		put in ‘Unavailable: Broken’ (U.B) state.
Production: Copy	P.C (PC)	Drive is receiving data from drain of Production drive.
Production: Draining	P.D (PD)	Drive is being drained.
Production:	P.I (PI)	Drive is part of array initialization process.
Initialize Array
		Drive is awaiting drain, but drain cannot start because:
Production:	P.P (PP)	•	Broken-to-spare data reconstruction is in progress
		•	Another drive in the array is being drained
Pending Drain
		•	The number of spares is inadequate (occurs if number of
			spares was reduced after drain request was accepted).
Production:	P.R (PR)	Data from broken drive is being reconstructed on spare drive,
Reconstruction		which moves to ‘P.A’ state when reconstruction finishes.
		Drive is broken but cause is unknown. Usually means data is be-
Production:	P.? (P?)	ing reconstructed to a spare, but may indicate other unknown
Unknown Drive State		state. After its data is moved, the broken drive moves from the
		Production partition to an ‘Unavailable: Broken’ (U.B) state.
	Media Acceptance Test (MAT) Partition
MAT: Active	M.A (MA)	Drive is active and available for allocation as a spare.
MAT: Fenced	M.F (MF)	Drive is fenced because GFR function is in progress.
		Drive is not active due to diagnostic error. After failure is isolated,
MAT: Drive Not Ready	M.? (M?)	broken drive is removed from MAT partition and put in ‘Unavail-
		able: Broken’ (U.B) state.
			Spares Partition
Spare: Active	S.A (SA)	Drive is available to form arrays, reconstruct data, or receive da-
		ta from drain operation.
Spare: Fenced	S.F (SF)	Drive is fenced for drive test.
Spare: Pending Drain	S.P (SP)	Drive is awaiting drain pending completion of drive test.
		Drive is not active for unknown reason (possible failure). After
Spare: Drive Failure	S.? (S?)	failure is isolated, broken drive is removed from Spares partition
		and put in ‘Unavailable: Broken’ (U.B) state.
			Unavailable Partition
Unavailable: Broken	U.B (UB)	Drive is broken.
Unavailable: Isolated	U.I (UI)	Drive is isolated from the SSA loop configuration.
Unavailable:	U.N (UN)	No active drive is sensed in this slot.
No Active Drive Module
Unavailable:	U.S (US)	No drive is installed in this slot.
Slot Not Installed
