error is reported to the event log. For virtual disks without redundancy
protection (RAID level 1, RAID level 5, and RAID level 6 virtual disks), the
error is not corrected but is reported to the event log.
• Recovered media error—Data could not be read by the physical disk on the
first attempt but was successfully read on a subsequent attempt. Data is
rewritten to the physical disk and verified and the error is reported to the
event log.
• 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.
