Removing A Task; Canceling A Task; Task Types - HP 3PAR StoreServ 7200 2-node Administrator's Manual

Removing a Task

The removetask command only works on completed, failed, and cancelled tasks. Information
about a task remains on the system unless it is manually removed using the removetask command
and the task ID. For example:
cli% removetask 454
Remove the following tasks?
454
select q=quit y=yes n=no: y
The specified task ID and any information associated with it are removed from the system. However,
task IDs are not recycled, so the next task started on the system will use the next whole integer that
has not already been used (for example, 455). Task ID numbers roll over at 9999.

Canceling a Task

For all task types except remote_copy_sync, scheduled_task, snapspace_accounting,
background_command, and system_task, you can cancel an active task using the canceltask
command and the task ID. For example:
cli# canceltask <task_ID>
select q=quit y=yes n=no: y
Information for the task will still be available with the showtask command, where the status of
the task will now appear as Cancelled.
