EDG8194I

Explanation
DFSMSrmm was unable to process an OAM request for
the volume because the OAM status for the volume is being changed
to SCRATCH and the DFSMSrmm status for the volume is MASTER or USER.
DFSMSrmm does not allow a volume's status to change from MASTER or
USER to SCRATCH by OAM, unless the volume is already a scratch candidate
volume. A scratch candidate is pending release and
the only pending action is "return to scratch".
In the
message text: function

This is the volume serial number being processing.

System action
EDGLCSUX performs no function.

System programmer response
If you want the volume to become a
SCRATCH volume, use the volume application of the DFSMSrmm ISPF dialog
to release the volume. Depending on the release actions for the volume,
the volume will return to be a scratch volume when the DFSMSrmm inventory
management next runs. If the volume is manually released,
it is a scratch candidate, and you can try the failed request again.
