Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the license agreement which
accompanied, or was contained in, the Program for which you are obtaining
the PTF.  You are not authorized to install or use the PTF except as part

APAR Error Description / Circumvention

-----------------------------------------------
Calling the SETASPGRP command specifying an IASP that is not
owned by that LPAR (such as a Target IASP used in a High
Availability Replication Product) can occasionally result in an
MCH3601 F/QYASPPG1 as a result of an uninitialized variable.

CORRECTION FOR APAR SE67173 :
-----------------------------
All variables are now initialized and the appropriate CPFB8ED
error message is sent.

CIRCUMVENTION FOR APAR SE67173 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR SE67495 :
-----------------------------------------------
After flashcopy, vary on IASP fails with MSGMCH5203. This
specific occurrence of a failed vary on is very rare; if an
unspecified error occurs during vary on of an IASP, a flag is
set to indicate that failure. Later in the vary on, the flag is
not checked before proceeding, and a resulting MCH5203 escape
message is signaled.

CORRECTION FOR APAR SE67495 :
-----------------------------
The vary on code path was changed to fail the vary on of an IASP
if the device description indicates that the device has failed.
The failure will send a CPFB8E5 escape message.

CIRCUMVENTION FOR APAR SE67495 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR SE67411 :
-----------------------------------------------
Vary on of IASP fails with MSGCPF980A due to an internal logic
error where the code returned a "True" value indicating that
IASP disks reported in when in reality the value should have
been "False" indicating that 6 minutes had passed and the disks
were not yet enlisted.

CORRECTION FOR APAR SE67411 :
-----------------------------
Code was enhanced to properly handle the condition of IASP disks
not reporting in and provide the correct message handling.

CIRCUMVENTION FOR APAR SE67411 :
--------------------------------
None.


Activation Instructions

Special Instructions


Once the PTF is applied, a new job must be started to pick up the new
code since the service programs contained in the PTF are activated into
the Default Activation Group.

********************************************************************
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 SI65393 :
=================================================

a new job MUST be started to activate the fix

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI64841 :
=================================================

Start a new job after applying this fix to activate the new code.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI64806 :
=================================================

Please start a new job in order to activate the fix.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI64167 :
=================================================

On each node in the cluster, end clustering, apply the fix, and then
start clustering.  It is not necessary to update all nodes at the same
time, however, any node without the fix will continue to be a potential
source of the problem.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI63655 :
=================================================

A new job must be started to activate the fix.
Additionally, the IASP must be varied off and varied back on for fix to
take effect.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI63448 :
=================================================

Any vary on or vary off requests AFTER this PTF is applied will contain
the vary request information enhancement.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI60534 :
=================================================

Start a new job after applying the PTF.
Additionally, to have DSPASPSTS panel reset its counters, you must vary
off then vary back on your IASP.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI60256 :
=================================================

IPL after applying or removing the fix.

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI58908 :
=================================================

You must IPL to apply the fix.
