HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

background_command
The background_command task type tracks commands initiated by the starttask CLI command.
The background_command task type has only one phase and one step.
• See the background_command task type in Table 10 (page 127) for a list of the commands
that can be run by the starttask command.
• See “Starting a Task” (page 124) for more information about the starttask command.
compact_cpg
The compact_cpg task type tracks the operations of the compactcpg command. For more
information about compacting CPGs, see “Compacting Common Provisioning Groups” (page 150).
The compact_cpg task type has only one phase, and the number of steps is equal to the number
of logical disk regions to be moved.
compact_lds
The compact_lds task type tracks the operations of the compactld command. For more
information about compacting logical disks, see “Compacting Logical Disks” (page 150). The
compact_lds task type has only one phase, and the number of steps is equal to the number of
logical disk regions to be 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 InForm OS 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 104)
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.
promote_sv
The promote_sv task type is used to track virtual copy snapshot promote operations. Promoting
a virtual copy snapshot copies the differences of the virtual copy back to its base volume. You can
promote a virtual copy snapshot using the promotesv command, see the “Promoting a Virtual
Copy” (page 101) for details. Virtual copy snapshots may also be automatically promoted by systems
using Remote Copy, for example when issuing the setrcopytargetreverse or
setrcopygrouptarget commands on a primary storage system or a system with primary
groups in order to reverse targets. Use of Remote Copy requires an HP 3PAR Remote Copy Software
license.
For promote_sv tasks, there is only one phase. The number of steps in that phase is equal to the
number of Gigabytes being copied.
NOTE: The promote_sv task type requires the HP 3PAR Virtual Copy Software license.
remote_copy_sync
The remote_copy_sync task type is used to track remote copy volume synchronizations on
systems using Remote Copy. Remote Copy is an optional volume mirroring solution that can be
used for disaster recovery and backup. The system creates a separate task for each primary volume
undergoing synchronization.
You can initiate Remote Copy volume synchronizations manually by issuing CLI commands, or it
can be performed automatically by the system. For instance, you can manually synchronize remote
