Using manual move control

You can override automatic processing and control volume movement manually by using the RMM CHANGEVOLUME subcommand with the MANUALMOVE operand. To return the volume to automatic movement control, use the RMM CHANGEVOLUME subcommand with the AUTOMOVE operand.

When you put a volume under manual move control, DFSMSrmm does not move the volume anywhere automatically, even when it expires and is pending release. Volume movement occurs only if you request it using the RMM CHANGEVOLUME subcommand with the LOCATION operand.

To allow release processing, you must remove the volume from manual move control unless the volume is in its home location. When a volume is in its home location, release processing is performed even if the volume is under manual move control.

You might use manual move control to keep volumes on-site even though they are flagged to be sent off-site for disaster recovery. To keep the volume on-site, or to request it be moved back to its home location, you could specify the RMM CHANGEVOLUME subcommand as shown in Figure 1.

RMM CHANGEVOLUME volser MANUALMOVE LOCATION(HOME)

When a volume is put under manual move control, any outstanding move is canceled. Moves can also be canceled by issuing the RMM CHANGEVOLUME subcommand with the LOCATION operand. The operand LOCATION(HOME) is specified in Figure 1 to cancel any pending moves because the volume is in its home location.

You might use manual move control for volumes you create on one system and then send to other systems for processing. Define the other systems as locations by using the parmlib LOCDEF command. When a volume is ready to be sent to the other system, you can confirm the volume move and put the volume under manual move control at the same time. For example, to send a volume to another system defined on a LOCDEF command as OTHER1, you can issue the command:

RMM CHANGEVOLUME volser LOCATION(OTHER1) CONFIRMMOVE MANUALMOVE

The MANUALMOVE operand shown in Figure 2 puts the volume under manual move control and cancels any outstanding moves. This prevents the volume from being moved automatically. The LOCATION operand sets the destination for volume. The CONFIRMMOVE operand shown in Figure 2 confirms that the volume move has completed. When the volume is returned from the other system, remove the volume from manual move control and confirm that the volume is back in its home location as shown in Figure 3.
