EDG2441I

Explanation
During inventory management, DFSMSrmm validates
the execution environment prior to using OAM services. DFSMSrmm detected
an error during validation.
In the message text: function
This is the DFSMSrmm control data set function requested and can
be: LOCATION
Checks that a volume destination is valid and that the volume
is defined in the volume catalog.
MEDIACNV 
Checks that the required location of the volume is a known store
location which supports the volume's media name.
SMSLEVEL
Checks that DFSMS/MVS is installed and that the SMS subsystem
is active.
TCDBVOL
Checks that a TCDB exists and contains at least one volume.
VOLUME
Checks that a volume is defined in the volume catalog.

identifier
identifier is provided only for the LOCATION
function, the MEDIACNV function, the VOLUME
function and identifies the volume being processed. DFSMSrmm does
not provide the identifier for the SMSLEVEL and TCDBVOL functions.
return_code
This is the return code set by either the CBRXLCS macro or SMS
or DFSMSrmm.
reason_code
This is the reason code set by either the CBRXLCS macro or SMS
or DFSMSrmm.

System action
 Inventory management abnormally ends with abend
code U2450 and DFSMSrmm writes an SVC dump in the following cases:For the LOCATION function if the return code is greater than 8.
For the MEDIACNV function if the return code is
greater than 8.
For the SMSLEVEL function if the return code is greater than 4.
For the VOLUME function if the return code is not equal to zero. 

If DFSMSrmm does not issue an abend, the current volume is skipped
and inventory management processing continues with the next volume.

Operator response
Inform the system programmer.

System programmer response
If the return code is 8, report the
problem to the IBM® Support Center.
Otherwise, refer to z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries 
for OAM return code and reason code explanations.
