APAR Error Description / Circumvention

-----------------------------------------------
While attempting concurrent maintenance against a failing slot,
the concurrent maintenance fails.  This could be an action such
as a Dynamic Logical Partitioning remove, a concurrent
maintenance repair, or a power off of a slot.

CORRECTION FOR APAR MA46049 :
-----------------------------
While the concurrent maintenance action was shutting down the
device, error recovery was still using it.  This caused an
exception in a critical path.  This timing window is very small.
In order for this problem to occur, the hardware essentially
must fail repeatedly, failing again every time recovery
completes.  The serialization between concurrent maintenance and
error recovery code paths has been enhanced.

CIRCUMVENTION FOR APAR MA46049 :
--------------------------------
None.
