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) | • | ||
• | 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 | ||||
