APAR Error Description / Circumvention

-----------------------------------------------
The CHGHYSSTS *SWAP command fails with message CPF9898, reason
code 5. Another symptom is CPI09B3 messages in the QSYSOPR
message queue indicating HyperSwap cannot be used. The problem
is caused by a race condition in the HyperSwap IPL path that
results in an internal state being incorrectly set that
indicates the HyperSwap configuration is not valid.

CORRECTION FOR APAR MA45721 :
-----------------------------
A PTF will be created to correct the problem. The PTF should be
applied to systems with DS8000 HyperSwap configured.

CIRCUMVENTION FOR APAR MA45721 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA45733 :
-----------------------------------------------
On a system with DS8000 HyperSwap disk units, some paths to
primary DS8000 volumes incorrectly indicate "Ineligible" status
after performing a CHGHYSSTS *SWAP. Another symptom of the
problem is paths to the primary DS8000 volume indicate "Unknown"
status after adding units to an ASP. The incorrect status
appears on the Display Disk Path Status display under the System
Service Tools (SST).

CORRECTION FOR APAR MA45733 :
-----------------------------
A PTF will be created to correct the problem. The PTF should be
applied to systems that have DS8000 HyperSwap configured.

CIRCUMVENTION FOR APAR MA45733 :
--------------------------------
None.
