--scan-array, -sa

The scan array option performs a continuous read operation of an array in the background, accessing every
block of the array from beginning to end. The array scan takes place only when the array is idle (that is, when
there is no input to or output from the array). This option uses --array as a qualifier.

--task, -t

The Task Control option allows you to pause/resume or to remove a running task. It can be used on create,
copy, consistency check, and bitmap check tasks. On transforms and restores for distributed and global
spares, task control can only pause/resume, but cannot remove the task.
If the running task is a copy, either the source array or the destination array can be used in the command. Be
aware that when a task is removed, data that was to be transferred in the portion of the task that did not finish
will be lost on the destination array.
This option uses --array as a qualifier.
