16.7.2 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, Managing Tasks, for information
about tasks and viewing tasks.
2 Issue the
tunevv rollback <VV_name> command.
16.7.3 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.
 To restart a Dynamic Optimization task, issue the tunevv restart <VV_name>
command.
NOTE: Rollback and restart operations should not be performed on Thinly-
Provisioned Virtual Volumes.
