Parameter Description
repositoryFullPolicy
Defines how Enhanced FlashCopy image processing
continues if the Enhanced FlashCopy group repository
logical drive is full. You can choose to fail I/O writes to
the base logical drive (
failBaseWrites ) or delete (purge) the
Enhanced FlashCopy images
(
purgeEnhancedFlashCopyImages ) in the repository logical
drive. The purgeEnhancedFlashCopyImages option deletes
the oldest Enhanced FlashCopy images to free up space.
The default action is
purgeEnhancedFlashCopyImages .
rollBackPriority Determines whether system resources should be
allocated to the rollback operation at the expense of
system performance. A value of
high indicates that the
rollback operation is prioritized over all other host I/O.

should be performed with minimal impact to host I/O.
The default value is
