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.
Production: Broken P.B (PB)
Drive is inactive and marked as broken. After its data is moved to
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:
Initialize Array
P.I (PI) Drive is part of array initialization process.
Production:
Pending Drain
P.P (PP)
Drive is awaiting drain, but drain cannot start because:
• Broken-to-spare data reconstruction is in progress
• Another drive in the array is being drained
• The number of spares is inadequate (occurs if number of
spares was reduced after drain request was accepted).
Production:
Reconstruction
P.R (PR)
Data from broken drive is being reconstructed on spare drive,
which moves to ‘P.A’ state when reconstruction finishes.
Production:
Unknown Drive State
P.? (P?)
Drive is broken but cause is unknown. Usually means data is be-
ing reconstructed to a spare, but may indicate other unknown
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.
MAT: Drive Not Ready M.? (M?)
Drive is not active due to diagnostic error. After failure is isolated,
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.
Spare: Drive Failure S.? (S?)
Drive is not active for unknown reason (possible failure). After
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:
No Active Drive Module
U.N (UN) No active drive is sensed in this slot.
Unavailable:
Slot Not Installed
U.S (US) No drive is installed in this slot.
