CMMVC9013E The FlashCopy mapping was not prepared because the mapping or consistency group is in the stopping state. The mapping or consistency group must first complete the stop operation and then be prepared
Explanation
You cannot prepare a FlashCopy mapping or consistency group when the FlashCopy mapping or consistency group is in the stopping state. If you want to prepare a FlashCopy mapping or consistency group, the FlashCopy mapping or consistency group must be in the Stopped or idle_or_copied state.
User response
Wait until the FlashCopy mapping or consistency group reaches the Stopped or idle_or_copied state and then resubmit the command.
