You cannot start a FlashCopy mapping or consistency group when a source VDisk in the FlashCopy mapping or consistency group is the target VDisk of another FlashCopy mapping that is holding the VDisk as inaccessible. The task cannot be initiated because a source VDisk in the FlashCopy mapping or consistency group that you are attempting to start is the target of another FlashCopy mapping that is either prepared, preparing, stopped or stopping with a progress of less than 100%.
Ensure that you have selected to start the correct FlashCopy mapping or consistency group. Ensure that none of the source VDisks in the FlashCopy mapping or consistency group that you specify are target VDisks in another FlashCopy mapping that is prepared, preparing, stopped or stopping with a progress of less than 100%. Resubmit the task.
