tape, the system attempted to update the use attribute of the tape
volume from scratch to private, but the use attribute was already
private.
In the message text: volser
The tape volume on which data set is open for output

System action
System updates fields in the tape volume record
for the tape volume, and updates the category of the volume in the
hardware inventory to private. Processing continues.

System programmer response
If this message appears frequently
or if you want to verify that other volumes do not have similar discrepancies,
use the DISPLAY SMS,VOLUME(volser) command to display
the use attribute setting in the tape configuration data base and
the corresponding category of the volume in the hardware inventory.
 Use the VOLUME ALTER command to make both settings the same.
