Starting a Task

You can use the starttask command to start a CLI command that runs as a
background_command task type. The background_command manages CLI commands with
long running times in the background so that multiple tasks can run concurrently. The
background_command task type can be managed with the task manager commands:
See Table 10 (page 126)
See the background_command task type in
that can be run by the starttask command.
If the command running as a background_command requires user confirmation, you must force
the command with the -f option.
To start a background_command task, issue the starttask <command_name> command,
where:
<command_name> is the name of the CLI command to run as a background_command.
For a complete list of options available for the starttask command, see the HP 3PAR Command
Line Interface Reference and the HP 3PAR CLI Help.

Displaying Task Information

Once a task is started, you can use the task ID to obtain information about the task. To see a list
of all tasks that have been active within the last 24 hours, you can use the showtask command
without specifying a task ID. For example:
cli% showtask
Id Type Name Status Phase Step -----Start_Time------
1 vv_copy vv1a done
2004
2 vv1b vv_copy active 2/3
All tasks are displayed by their task IDs, including active and completed tasks. The system stores
information for up to 1,000 tasks. You can use the showtask-t <hours> command to show
tasks older than 24 hours.
You can use the showtask -d command and the task ID to display status information about a
specific ongoing or completed task. Task 454 is shown in the following example:
cli% showtask -d 454
Id Type
