APAR Error Description / Circumvention

-----------------------------------------------
If an RDX dock with device firmware level 227 is connected, the
system performance of save operations to the device is much
slower than expected.

CORRECTION FOR APAR MA45249 :
-----------------------------
The device responds differently during device identification,
and the device driver incorrectly sets up the vital product data
for how the device manages it's cache.  Apply this fix to
correctly identify device cache operations and improve the
device performance after the next IOA or System IPL.

CIRCUMVENTION FOR APAR MA45249 :
--------------------------------
None.
