Damage occurs to the storage device where a data file resides.
In this case, you can restore the damaged data file, the index, and the audit file from a backup device. When the failure occurs, the observations or records that were not written to the data file or catalog are lost and some of the information about where values are stored is inconsistent. If the audit file for a SAS data file becomes damaged, you will not be able to process the data file until you terminate the audit trail. Then, you can initiate a new audit file or process the data file without one. This specification gives the application control over the repair decision and provides awareness that a problem occurred.
