Start Enhanced FlashCopy Image Rollback
This command starts a rollback operation for a set of Enhanced FlashCopy images. The content of the
base logical drive changes immediately to match the point-in-time content of the selected Enhanced
FlashCopy image logical drive. The base logical drive immediately becomes available for read/write
requests after the rollback operation has successfully completed. To stop an Enhanced FlashCopy image
rollback operation, use the stop rollback
enhancedFlashCopyImage
command.
The repository logical drive that is associated with the Enhanced FlashCopy image continues to track any
new changes between the base logical drive and the Enhanced FlashCopy image logical drive that occur
after the rollback operation is completed.
Note: You cannot use this command for Enhanced FlashCopy images involved in online VolumeCopy.
