APAR Error Description / Circumvention

-----------------------------------------------
Capture additional data when an error is detected by the device
driver.

CORRECTION FOR APAR MA45947 :
-----------------------------
Apply this fix to allow IBM to more quickly determine the cause
of a tape problem.

CIRCUMVENTION FOR APAR MA45947 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA45948 :
-----------------------------------------------
If a tape drive reports an error on a read as recovered, but
does not transfer data, the LIC code may not report an error on
the operation to the operating system. This can result in the
client code attempting to process a data buffer that has no
valid data.

CORRECTION FOR APAR MA45948 :
-----------------------------
Apply this fix to change the LIC code to ensure that all data
length errors are reported to the operating system.

CIRCUMVENTION FOR APAR MA45948 :
--------------------------------
None.


Activation Instructions
