As logical volumes are exported, DFSMSrmm tracks the 'in container' stacked volume and drives movement based on the destination of logical volumes. Use DFSMSrmm export processing to remove logical volumes from a VTS.

1. Define vital record specifications that specify locations to which data sets in the VTS should be moved.
2. Run DFSMSrmm inventory management vital records and storage location management processing to determine which logical volumes should be moved. DFSMSrmm allocates a bin number to the volume if the volume's destination is shelf-managed. There will be unused bin numbers for logical volumes that are moving to shelf-managed storage locations. You will waste bin numbers because EDGRPTD ignores the assigned bin numbers for logical volumes.
3. Create a list of volumes to export. Create the list after you run storage location management. The moves are those that are identified during vital record processing or those changes that are made when you issue the RMM CHANGEVOLUME subcommand. Use the RMM SEARCHVOLUME subcommand to obtain volume information for the list as shown in Figure 1.

   DFSMSrmm returns a list of volumes to export that you can use as input for creating the export list logical volume file 1. See these examples in SYS1.SAMPLIB for the format and required files for the export list volume.
   • CBRSPSXP — sample JCL for export list volume scratch request.
   • CBRSPPXP — sample JCL for export list volume private request.
   You can track the movement of logical volumes by using the LOCATION field and DESTINATION field of the volume information.
4. Start the export process as described in the z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries using the LIBRARY EXPORT command or use the CBRSPLCS sample program.

   The VTS export process runs asynchronously to DFSMSrmm processing. Once the export request has been initiated, VTS library signals trigger DFSMSrmm actions related to export processing.

   During the VTS export process, logical volumes are copied to a stacked volume, and the stacked volume is completed. For each logical volume copied to the stacked volume, DFSMSrmm is notified of both the logical volume and stacked volume. DFSMSrmm updates the DFSMSrmm control data set with the volume serial number of the stacked volume as the 'in container'.

5. After export VTS processing is completed, you can run DFSMSrmm inventory management report extract processing to obtain information about the volumes that were processed.
6. Create movement report and pick lists by using the DFSMSrmm EDGRPTD report utility.
7. Use the movement reports to eject the stacked volumes from the VTS using the library manager and move them to the destination storage location. Transfer the stacked volumes in the export hold category to the exit station using the library manager console.
8. Physically move the stacked volumes listed in your movement report from the VTS exit station to the destination storage location.
9. Confirm that volumes have been moved. When the stacked volume is moved, you must confirm the move for all the logical volumes that reside on the volume. Use the RMM CHANGEVOLUME subcommand as shown in Figure 2 to confirm the completion of the movement of volumes.
