APAR Error Description / Circumvention

-----------------------------------------------
If two cartridges have the same barcode in a 3584, and both are
located in slots, the IOPless device driver will not allow one
of them to be moved, making it difficult to remove one of the
duplicates from the library.

CORRECTION FOR APAR MA42241 :
-----------------------------
Apply this fix to allow duplicate cartridges to be moved similar
to the IOP attached solution. One must be removed from the
library to recover usability.

CIRCUMVENTION FOR APAR MA42241 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA42191 :
-----------------------------------------------
WRKMLMBRM doesn't show some volumes, but WRKMEDBRM does. SLIC
Tape cartridge inventory buffer is too small and request to
increase the buffer was not sent.

CORRECTION FOR APAR MA42191 :
-----------------------------
Problem may occur when the inventory size is increased and the
new media appears at the very end of the inventory list.  Apply
this fix to correct the problem.

CIRCUMVENTION FOR APAR MA42191 :
--------------------------------
None.

Special Instructions


********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF55409 :
=================================================

This fix provides support for up to 15000 storage elements in an
attached 3584 or ProtecTIER library.
The time required for a media library to respond to the system for an
inventory request is significant, and a larger library will appear
slower to both the user interface and to applications. The tape library
response will get progressively slower as the number of elements
increases and having multiple hosts actively using the tape library
will also slow down the response times. The point at which the
performance is not acceptable depends on the workload mix, the number
of controlling systems, and the timing of the jobs running on the
systems. IBM cannot identify the general case where the performance
becomes an issue. If a large library configuration is not fast enough
in your environment, reduce the number of storage slots.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
