Possible Cause:  The system found the remirroring process to be out of synchronization due to hardware failure. The designated partition cannot be mirrored. Data integrity might be lost for the volumes that reside on the designated partition. The operating system supports the partition as an unmirrored device. This error might have been caused by a hard disk or channel failure. Another possibility is that the directory was corrupted.

Action:  Try to salvage the data on the mirrored disks. See "Recovering Data from an Out of Sync Disk in the Server Operating System Administration Guide. Replace failing disks.
