Change the Priority Level of a Task
The task priority feature allows the user to speed up or slow down tasks being performed on arrays.
To decrease the amount of time it takes for a task to complete, set the task priority higher (10 is the highest).
NOTE:
A task priority can only be changed after a task is running on the array.
NOTE:
Tasks include operations such as a Transform, Copy, or Consistency Check.
To change a task priority
1.
Click the array.
2.
From the Array drop-down menu, select
Task -> Priority
.
3.
Change the task priority by clicking the slider and moving it one way or the other.
Interrupt or Cancel a Task
The Task Control commands allow the user to pause, resume, or cancel (remove) tasks being performed on
arrays.
Full task control can be used on Create, Copy, Consistency Check, and Bitmap_Check tasks. On Restores with
dedicated or global spares the task can be removed, but the array will return to the Critical state.
NOTE:
Task control can only be used when a task is running on the array.
