Use the stopfcconsistgrp command to stop all processing that is associated with a FlashCopy® consistency group that is in one of the following processing states: prepared, copying, stopping, or suspended.
If the -force parameter is specified, any Metro Mirror or Global Mirror relationships associated with the target volumes of the FlashCopy mappings in the specified consistency group stops. If a remote copy relationship associated with the target was mirroring I/O when the map was copying, it might lose its difference recording capability and require a full resychronization upon a subsequent restart.
This command stops a group of mappings in a consistency group. If the copy process is stopped, the target disks become unusable unless they already contain complete images of the source. Disks that contain complete images of the source have a progress of 100, as indicated in the lsfcmap command output. The target volume is reported as offline if it does not contain a complete image. Before you can access this volume, the group of mappings must be prepared and restarted.
The split option can be used when all of the maps in the group have progress of 100. It removes the dependency of any other maps on the source volumes. It might be used prior to starting another FlashCopy consistency group whose target disks are the source disks of the mappings being stopped. Once the consistency group has been stopped with the split option, the other consistency group could then be started without the restore option.
