Message Text

Database mirroring is disabled due to a failed redo operation. Unable to resume.

Database mirroring failed to redo a log record on the mirror.

Possible Causes

The most likely cause is that an add-file operation completed on the principal database but then failed on the mirror database because file names or directory structures differ on the principal server and mirror server.

Look in the SQL Server error log for the cause of this error. Try to resolve the cause and resume mirroring on the database.
