• 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.
