APAR Error Description / Circumvention

-----------------------------------------------
When saving a network server storage space while active, when
the storage space does not have an NWSD linked,  error messages
MCH3401 and CPDA4CE are sent.

================================
Message ID . . . . . . :   MCH3401       Severity . . . . . . .
:   40
Message type . . . . . :   Escape

Date sent  . . . . . . :   07/16/12      Time sent  . . . . . .
:   15:18:39


Message . . . . :   Cannot resolve to object . Type and Subtype
X'1D01' Authority X'0000'.

Cause . . . . . :   Either a system pointer or a data pointer
can not be resolved.


Message ID . . . . . . :   CPDA4CE       Severity . . . . . . .
:   30
Message type . . . . . :   Diagnostic

Date sent  . . . . . . :   07/16/12      Time sent  . . . . . .
:   15:18:39


Message . . . . :   Network server storage space xxxx will be
saved with inconsistent data.


================================

The issue occurs when a storage space saved while active
attempts to notify the integrated server to thaw the
applications after a check-point on the object is achieved.  For
a storage with no NWSD linked, there is no NWSD to receive the
thaw requests resulting in error MCH3401. Since an error was
returned and the save continues, CPDA4CE is sent saying the save
will continue with inconsistent data.

CORRECTION FOR APAR SE52564 :
-----------------------------
The code is updated to not attempt reading NWSD information if
the storage space was not linked prior to starting the save
while active process.

CIRCUMVENTION FOR APAR SE52564 :
--------------------------------
None.
