APAR Error Description / Circumvention

-----------------------------------------------
Additional diagnostic capability is needed to shorten the time
it takes to diagnose problems.



If a tape device in a library does not report in soon enough
after the mover reports in the TAPMLB device description may not
vary on during autoconfiguration or during a partition IPL.

CORRECTION FOR APAR MA38926 :
-----------------------------
Added additional diagnostic capability.



The code was changed to wait 6 seconds and check for a tape
drive again. This will be done for up to 3 retries. This will
allow for a tape library to vary on during autoconfiguration or
a partition IPL if the tape drive reports in a few seconds after
the mover.

CIRCUMVENTION FOR APAR MA38926 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA38996 :
-----------------------------------------------
A tape resource may be incorrectly left reserved, after an error
occurs, preventing it from being used by another host.

CORRECTION FOR APAR MA38996 :
-----------------------------
The Licensed Internal Code for tape has been changed to release
the drive after an error when appropriate to do so.

CIRCUMVENTION FOR APAR MA38996 :
--------------------------------
None.
