CMUN03027E commitflash: 0003:0003: FlashCopy operation failure: action prohibited by current FlashCopy state
The following explanations apply to the cases presented in Example 9-4:
򐂰 Example 1: commit the FlashCopy relationship.
This example shows the properties of the two FlashCopy relationships 0001:0101 and
0005:0105 using the lsflash command prior and after issuing the setflashrevertible
command. After the commitflash command is executed the properties of the two
FlashCopy relationships are listed again.
򐂰 Example 2: error occurs when trying to commit FlashCopy relationship.
When trying to commit a FlashCopy relationship that isn’t revertible (property Revertible is
disabled) an error will be the result. The script will end after this command with return code
2 and any other commands following the one that causes the error will not be executed.
Incremental FlashCopy using resyncflash
With the resyncflash command an existing FlashCopy relationship can be incremented. To
run this command, the FlashCopy relationship must have the options Recording and
Persistent enabled.
To make sure an existing FlashCopy relationship can be incremented multiple times, it is
necessary to repeat the -record and -persist parameters with the resyncflash command.
Example 9-5 shows examples where the resyncflash command is used.

Tip: You do not have to wait for the background copy to complete before you do the Flash-
Copy resynchronization. The resyncflash command can be used at any time.
