These ASPs are configured for mirrored protection. If the failing disk drive has mirrored protection, record the status of both disk drives in the mirrored pair. You need this information in the recovery procedure. Unprotected. An ASP with a status of Unprotected might contain disk drives that are device parity protected. Record the status of the failing disk drive as it is shown in the Status column of the Display Disk Configuration Status display. A disk drive with one of the following statuses has device parity protection only if all other disk drives in the array are operational: DPY/Active DPY/Failed DPY/HDW Failure DPY/Degraded DPY/Power Loss DPY/Not Ready DPY/Unknown A disk drive with any other status (such as DPY/Rebuild or DPY/Unprotected) does not have device parity protection.
