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 11 (page 130) for a list of the commands that can be run by the starttask command. See "Starting a Task" (page 127) 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 179). 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 "Compacting Logical Disks" (page 178). The compact_lds 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 "Promoting a Virtual Copy" (page 96) 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 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. 132 Managing Tasks
