Stopping FlashCopy mappings by using the CLI

You can use the command-line interface (CLI) to stop a mapping.

Follow these steps to stop a single stand-alone mapping.
  1. To stop a mapping, issue the following stopfcmap command:
    stopfcmap fc_map_id or fc_map_name

    where fc_map_id or fc_map_name is the ID or name of the mapping to stop.

  2. To stop immediately all processing that is associated with the mapping and break the dependency on the source volume of any mappings that are also dependent on the target disk, issue the following command:
    stopfcmap -force -split fc_map_id or fc_map_name

    When you use the force parameter, all mappings that depend on this mapping (as listed by the lsfcmapdependentmaps command) are also stopped.

    Important: Using the force parameter might result in a loss of access. Use it only under the direction of the IBM Support Center.

    The split parameter can be specified only when stopping a map that has a progress of 100 as shown by the lsfcmap command. The split parameter removes the dependency of any other mappings on the source volume. It might be used before starting another FlashCopy mapping whose target disk is the source disk of the mapping that is being stopped. After the mapping is stopped with the split option, you can start the other mapping without the restore option.
