1600 Mirrored disk repair halted because of difference.

Explanation
During the repair of a mirrored volume two copy
disks were found to contain different data for the same logical block
address (LBA). The validate option was used, so the repair process
has halted.
Read operations to the LBAs that differ might return
the data of either volume copy. Therefore it is important not to use
the volume unless you are sure that the host applications will not
read the LBAs that differ or can manage the different data that potentially
can be returned.

User response
Perform one of the following actions:

Continue the repair starting with the next LBA after the difference
to see how many differences there are for the whole mirrored volume.
This can help you decide which of the following actions to take.

Choose a primary disk and run repair resynchronizing differences.

Run a repair and create medium errors for differences.

Restore all or part of the volume from a backup.

Decide which disk has correct data, then delete the copy that
is different and re-create it allowing it to be synchronized.

Then mark the error as fixed.
