If you enable extended bin support, you can specify that DFSMSrmm make bins available for reuse when volume moves have started. To make bins available for reuse when a volume move is started, specify the DFSMSrmm parmlib OPTION command REUSEBIN(STARTMOVE) operand. The default operand is REUSEBIN(CONFIRMMOVE), whether extended bin support is enabled or is not enabled. See Defining system options: OPTION for detailed information.

To enable extended bin support, create or update the control data set control record using EDGUTIL with the EXTENDEDBIN(YES) option. See Creating or updating the control data set control record for detailed information.
