Changing the use attribute from private to scratch

If the storage administrator uses the ALTER command to specify a NEW VALUE of scratch for the use attribute and any of the volumes on the list are private with an expiration date that has not yet passed, the Private to Scratch Confirmation Panel (Figure 1) is displayed for each volume whose expiration date has not yet passed.

Note: When DFSMSrmm is installed, any attempt to alter the use attribute from private to scratch will be rejected.

 Command ===>
 
 
                       Confirm Alter of Volume: EMB001
 
         Currently this Volume is Private and
         Its Expiration Date has not yet Passed.
 
 Enter "/" to select option   _  Do you still want to change it to scratch?
 
         You may specify that all private volumes on
         the list should be changed to scratch whether
         or not their expiration dates have passed.
         If you do, the volumes will be changed without
         redisplaying this confirmation panel.
 
 Enter "/" to select option   _  Allow All Private Volumes to be
                                 Changed to Scratch?
 
 Use ENTER to Perform Operation;
 Use HELP Command for Help; Use END Command to Exit.
If the response is / on either confirmation panel, OAM changes the following items:
  • The use attribute is changed to S in the TCDB.
  • The storage group name is set to *SCRTCH* in the TCDB.
  • The expiration date in the TCDB is blanked out.
  • The volume error status is reset to NO ERROR in the TCDB.
  • The library manager category of the cartridge is changed from private to scratch (ATLDS only).
Note: The change use attribute installation exit (CBRUXCUA) is invoked whenever there is an attempt to change the use attribute for a tape volume. It may override the request or change the values. See Change use attribute installation exit (CBRUXCUA) for more information on this installation exit.
