Changing the use attribute from scratch to private

When the ALTER line operator or the ALTER command changes the use attribute for a single tape volume or a list of tape volumes to private, the following items are performed:

The use attribute is changed to P in the TCDB.
The volume error status is reset to NO ERROR in the TCDB.
The category of the cartridge or cartridges is changed from scratch to private (ATLDS only).

The changes to the TCDB volume record are performed immediately. When the line operator or command is complete, the user is returned to the Mountable Tape Volume List panel with the appropriate success or failure message. If the volume or volumes were successfully changed, the ISMF REFRESH command may be used to display the new values in the tape volume record.
