Managing tasks

This module describes how to manage tasks.

About tasks

When you perform any operation, P9000 Command View AE Suite registers the operation as a task.

When a task is registered, P9000 Command View AE Suite reserves any resources that the task
requires (such as, volumes, parity groups, pools, host groups), and denies access to other operations
until the task either completes or is canceled.

If the server stops before a task starts, the task will run the next time the server starts. If the server stops
while a task is running, the task will fail. Scheduled tasks can be rescheduled after the server is
restarted.

You can check the progress or the results of all previously executed tasks on the Tasks & Alerts tab.

NOTE:

Information about previously run tasks is automatically deleted, starting with the oldest task, after the
number of tasks exceeds 100,000. Tasks can also be deleted manually.

Until the task is complete, do not perform operations on any volume included in the task by using
P9000 Command View AE Suite or any other program.

Viewing task status

Viewing the status of a task allows you to see if a task has completed as well as other details.
