13.3.6 tune_vv_restart
The tune_vv_restart task type is used to track tunealdvv -restart operations
performed with the 3PAR System Tuner
tunealdvv -restart command. The tunealdvv -
restart
command enables users to resume a failed or cancelled tunealdvv operation. Use
of this feature requires a 3PAR System Tuner license.
The following examples shows how to start, cancel, and then restart a
tunealdvv operation
on virtual volume
testvol:
Note that the
tune_vv_restart task is a new task and takes a new task ID number.
After restarting the
tunealdvv operation, you can use the showtask command to see the
cancelled and restarted tasks:
For
tune_vv_restart tasks, there are two phases:
 Phase 1: performing the actual region moves.
 Phase 2: deleting the information stored in Phase 1 of the corresponding tune_vv task.
The number of steps in the phase is equal to the number of regions being moved.
For more information on 3PAR System Tuner and the
tunealdvv command see Chapter 15,
Using Dynamic Optimization, and the InForm OS Command Line Interface Reference.
