doubly allocated file extents remain:
•
If none remain, you are finished with the procedure and you can restart 
applications. 
•
If doubly allocated file extents remain, continue to the next step. 
2. Use FUP DUP or BACKUP to copy to another volume the files identified in the 
DSAP report that contain doubly allocated extents. 
3. Purge these files from the original volume. 
If purging a file causes file-system errors, resolve them by repeating Step 4.
4. Repeat Identifying Doubly Allocated File Extents on page 7-17 to ensure that all 
doubly allocated file extents have been corrected. If none remain, continue with the 
next step.Otherwise, repeat from Step 2. 
5. Use FUP DUP or RESTORE to copy the files back to the original volume. 
6. Restart applications.
