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
can be run by the starttask command.
See "Starting a Task" (page 127)

compact_cpg

The compact_cpg task type tracks the operations of the compactcpg command. For more
information about compacting CPGs, see
The compact_cpg task type has only one phase, and the number of steps is equal to the number
of LD regions to be moved.

compact_lds

The compact_lds task type tracks the operations of the compactld command. For more
information about compacting LDs, see
task type has only one phase, and the number of steps is equal to the number of LD regions to be
moved.

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
Copy" (page 96)
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
copy volume groups using the command. Restarting remote copy volume groups, by using the
startrcopygroup command, can also initiate a remote copy synchronization on the system.
However, with periodic mode volume groups, the startrcopygroup command will initiate
synchronization only the first time that it is issued for that volume group. In addition, periodic mode
remote copy volume groups may be automatically resynchronized by systems using Remote Copy,
but only if the resynchronization period has been set for the volume groups.
