1600 Mirrored disk repair halted because of difference.

Explanation

During the repair of a mirrored VDisk 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 either VDisk Copy's data. Therefore it is important not to use the VDisk 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.

Action

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 VDisk. 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 VDisk from a backup.
Decide which disk has correct data, then delete the copy that is different and recreate it allowing it to be synchronized.

Then mark the error as "fixed".
