APAR Error Description / Circumvention

-----------------------------------------------
If a partiion has disk units with 512-byte sectors, and the disk
units are mirror protected with system level mirroring, and
there is an error that occurs which causes the mirror subunit to
go into error recovery and be suspended, there is a case where
the data page is not constructed correctly.

Service Keywords:
CPI0949 - "Mirrored protection suspended on disk unit"

CORRECTION FOR APAR MA46641 :
-----------------------------
The system licensed internal code is changed to use the correct
IO request after the mirror error recovery completes.

CIRCUMVENTION FOR APAR MA46641 :
--------------------------------
None.
