13.3.8 tune_vv_restart
The tune_vv_restart task type is used to track tunevv restart operations performed
with the 3PAR System Tuner
tunevv restart command. The tunevv restart command
enables you to resume a failed or cancelled
tunevv operation.
The following examples shows how to start, cancel, and then restart a
tunevv 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
tunevv 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 about the 3PAR System Tuner and the
tunevv command, see
Chapter 16, Performance Tuning.
