Task Types
InForm OS Version 2.3.1 3PAR InForm CLI Administrator’s Manual
13.3.4 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 InForm OS
Command Line Interface Reference for details).
You can resynchronize a physical copy using the
createvvcopy command with the -r
(resync) option (see 8.3.2 Resynchronizing a Physical Copy on page 8.7 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.
13.3.5 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
8.2.2 Promoting a Virtual Copy on page 8.3 for details). In addition, virtual copy snapshots may
be automatically promoted by systems using 3PAR Remote Copy, for example when issuing the
setrcopytarget reverse or setrcopygroup target commands on a primary storage
system or a system with primary groups in order to reverse targets. Use of Remote Copy
requires a 3PAR Remote Copy 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.
13.3.6 remote_copy_sync
The remote_copy_sync task type is used to track remote copy volume synchronizations on
systems using 3PAR Remote Copy. 3PAR 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
syncrcopy command. Restarting remote copy volume
NOTE: The promote_sv task type requires the 3PAR Virtual Copy license.
