Cause. A checksum error was detected on one disk drive of a mirrored volume, but
was successfully read from the other disk drive. In order to provide the highest data
availability, DP2 Driver has rewritten the good block back out to the disk drive that
returned the checksum error.
Effect. None.
Recovery. This is an informational message only; no corrective action is needed.
