Redundancy mismatches error—The first 10 redundancy mismatches that are found on the virtual disk are reported to the event log.

Unfixable error—Data could not be read and parity or redundancy information could not be used to regenerate the data. For example, redundancy information cannot be used to reconstruct the data on a degraded virtual disk. The error is reported to the event log.

7To enable or disable the consistency check, select either With consistency check or Without consistency check.

NOTE: A consistency check scans the data blocks in a RAID Level 5 virtual disk, or a RAID Level 6 virtual disk and checks the consistency information for each block. A consistency check compares data blocks on RAID Level 1 mirrored physical disks. RAID Level 0 virtual disks have no data consistency.
