APAR Error Description / Circumvention

-----------------------------------------------
During a MSD IPL the changed page reclaimator fails, resulting
in a full directory recovery.  The exception is caused due to
incorrect information in a page descriptor at the time of the
MSD.  The incorrect information is seen due to the order of
updates to the page descriptor.

CORRECTION FOR APAR MA46274 :
-----------------------------
The code which updates page descriptor information is changed to
store the information in the correct order, so that the changed
page reclaimator will no longer take an exception while
processing.

CIRCUMVENTION FOR APAR MA46274 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions
