HP 3PAR OS 3.1.3 CLI Administrator's Manual

The number of steps in the phase is equal to the number of regions being moved.
vv_copy
The vv_copy task type is used to track physical copy operations. This includes creating physical
copies and resynchronizing a physical copy with its parent base volume. You can create physical
copies using the createvvcopy command. See the HP 3PAR Command Line Interface Reference
for details. You can also resynchronize a physical copy using the createvvcopy command with
the -r resyncronization option. See “Resynchronizing a Physical Copy” (page 106) for details.
For vv_copy tasks, there is only one phase. The number of steps in that phase is equal to the
number of gigabytes being copied.
System Scheduler
The System Scheduler allows you to create, modify, and remove schedules for initiating system
operations with long running times. With the System Scheduler, commands you can schedule
specific CLI commands to run at regularly scheduled intervals, or to run once at a specified time.
