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 99) 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. System Scheduler Commands Table 12 (page 137) summarizes the System Scheduler commands.
