DFS2675A I/O ERROR OCCURRED WHEN ATTEMPTING TO READ FROM AREA=areaname UOW=nnnnnnnn IN (BUILD|COPY) PHASE

Explanation

The DEDB Direct Reorganization utility, DBFUMDR0, attempted to read from the area and unit of work, nnnnnnn, and encountered an I/O error.

BUILD in the message text indicates that this message was issued during the build phase of the DEDB Direct Reorganization utility. An error occurred while reading from the original UOW. The area is still usable, but all the data sets have unreadable control intervals with the same relative byte address (RBA) in the original UOW of each data set.

COPY in the message text indicates that this message was issued in the copy phase of the DEDB Direct Reorganization utility. An error occurred while reading from a reorganized UOW. The system stops the area and set the area to a recovery-needed status.
