APAR Error Description / Circumvention

-------------------------------------------------
If commands that are being sent to a tape drive are timing out,
an attempt to vary on the tape drive or allocate it to a tape
library can take a long time before failing.
Before the failure occurs the QTAPARB job is in a wait state
preventing other tape devices from varying on or drive
allocations for other tape libraries from being changed.

CORRECTION FOR APAR 'MA48679' :
-------------------------------
The code has been changed to fail the allocation faster. This
will allow other tape devices to be varied on or allocation
changes to be made without waiting a long time for the
allocation of the bad device to fail.

CIRCUMVENTION FOR APAR 'MA48679' :
----------------------------------
None.


Activation Instructions

None.




Special Instructions

None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
