Every failure has a failure status: OPEN or CLOSED.
The status of a failure is OPEN until the appropriate repair action is invoked. The status changes to CLOSED after the failure is repaired.
Every time you execute LIST FAILURE , Data Recovery Advisor revalidates all open failures and closes failures that no longer exist. Thus, if you fixed some failures as part of a separate procedure, or if the failures were transient problems that disappeared by themselves, running LIST FAILURE automatically closes them.
You can use CHANGE FAILURE to change the status of an open failure to CLOSED if you have fixed it manually. However, it makes sense to use CHANGE FAILURE … CLOSED only if for some reason the failure was not closed automatically. If a failure still exists when you use CHANGE to close it manually, then Data Recover Advisor re-creates it with a different failure ID when the appropriate data integrity check is executed.
