Scheduled_Task; Snapspace_Accounting; Startao - HP 3PAR StoreServ 7200 2-node Administrator's Manual

For remote_copy_sync tasks, there are three phases:
Phase 1 (startup): sync request has been received and synchronization is scheduled to start.
Phase 2: performing the resynchronization.
Phase 3: copying has completed and cleanup (such as deleting snapshots and setting state
values) is taking place.
In the showtask output, the Step column indicates the completed and total volume size, in MBs,
using the format <completed_size>/<total_size>.
For remote copy synchronizations, the finish time in the showrcopy output for the resynchronization
task may not match the LastSync column in the showrcopy command output for the system holding
the primary volumes. This is because the times are taken at different points in the process. The task
time is set by the task subsystem when it is marked as completed, whereas the LastSync time
is set when remote copy completes the sync. These two times should be similar, but may differ by
up to a few seconds.
You cannot use the canceltask command to cancel a remote copy synchronization task.
For details about volume synchronizations and remote copy commands, see the HP 3PAR Remote
Copy Software User's Guide.
NOTE: The remote_copy_sync task type requires the HP 3PAR Remote Copy Software license.
The tunevv CLI command requires the HP 3PAR Dynamic Optimization Software license.

scheduled_task

The scheduled_task task type is used to track system operations initiated by the System Scheduler
commands. See
Table 13 (page 137)
Scheduler commands. The scheduled_task task type has only one phase and one step.

snapspace_accounting

The snapspace_accounting task type tracks the progress of the snapshot space usage
accounting process and runs the updatesnapspace command. The snapshot space usage
displayed by showvv-s is not necessarily the current usage. You have to issue the showvv -hist
command to display the last time updatesnapspace was run on the virtual volumes. The
TimeCalculated column shows the last time the usage was calculated. The updatesnapspace
command causes the system to begin calculating current snapshot space usage. If one or more
virtual volume names or patterns are specified, only the specified virtual volumes are updated. If
no virtual volume names are specified, all virtual volumes are updated.
The updatesnapspacecommand immediately returns the task ID associated with the updated
snapshot space usage accounting process. The canceltask command cannot be used to cancel
the snapspace_accounting task type. To wait for completion, use the waittask command.
The snapspace_accounting task type has only one phase, and the number of steps is equal
to the number of virtual volumes affected by the updatesnapspace command.

startao

When a startao command is scheduled, the user-defined schedule name appears in the list of
schedules. The startao command syntax and operation are described in the HP 3PAR Command
Line Interface Reference, "Start Commands" section. For more information about Adaptive
Optimization concepts and usage, see
Table 12 (page 137) for a complete list of the System Scheduler commands. See
for a complete list of the CLI commands that can be initiated with the System
"Adaptive Optimization" (page 140).
