APAR Error Description / Circumvention

-----------------------------------------------
When a tape library with multiple control paths is initially
attached, multiple tape library resources may be created when
only one should have been created. When the LPAR or IOA is IPLed
the extra tape library resources will show up as not detected.
If one of the resources being used from the initial attachment
is one of those that goes not detected the user has to switch to
using the remaining reported resource. This problem only occurs
with the initial attachment.

CORRECTION FOR APAR MA39883 :
-----------------------------
Apply this fix to prevent incorrect multiple library resources
from being created on the initial connection of a new tape
library.

CIRCUMVENTION FOR APAR MA39883 :
--------------------------------
None.
