You cannot delete a FlashCopy repository logical drive using the Delete Logical Drive option, but you can using the delete command in the Script Editor or Command Line Interface. See the Enterprise Management Window online help system for more information on using the delete command.
Deleting a logical drive that is participating in a Remote Mirrorrelationship removes the mirror relationship on both the local and remote storage subsystems.
