15.10.1 Rolling Back a Dynamic Optimization Operation
Rolling back a dynamic optimization task restores a volume to its state prior to the initiation of
the task. Essentially, issuing a rollback command performs an undo of the operation. You may
choose to roll back a dynamic optimization task if the operation was interrupted because of:
 Lack of space.
 User-initiated cancellation of a task.
To perform a rollback operation, perform the following:
1 Issue the
canceltask <task_ID> command, where <task_ID> is the ID of the dynamic
optimization task you wish to cancel. Refer to Chapter 13, Task Management, for
information about tasks and viewing tasks.
2 Issue the
tunevv rollback <VV_name> command.
15.10.2 Restarting a Dynamic Optimization Operation
Restarting a dynamic optimization task restarts a task that was previously interrupted. You
may choose to restart a dynamic optimization task if the operation was interrupted because
of:
 User-initiated cancellation of a task.
 Component failure.
X To restart a dynamic optimization task, issue the tunevv restart <VV_name>
command.
