You can also set the rate at which background tasks are performed compared
to I/O tasks. For more information, see “Setting Background Task Rate” on
page 172.
Scheduled Task Duration
If a rebuild does not complete in a scheduled time block, it will pause and
continue where it left off at the next scheduled time block.
This is also true for verify, if you use the Advanced Verify schedule. If you
use the Basic Verify Schedule, verifies will run to completion, and are not
limited to a specific duration.
Viewing Current Task Schedules
You can see the current schedules for background tasks on the Scheduling
page.
To view the current task schedule
1 Choose Management > Schedule from the menu bar.
The Scheduling page appears, showing the schedule for Rebuild Tasks.
(Migration and initialization tasks follow the Rebuild Task schedule.)
2 To view Verify Tasks or Self-test Tasks, select it from the drop-down list
at the top of the page.
Note : Setting up the scheduling window does not actually request background
tasks. It simply specifies when they can run. For more information about the
background tasks themselves, see “Background Tasks” on page 158.
Note: When using Basic Verify Schedule and Auto Verify, if the system is off at the
scheduled time, a Verify will start when the system is powered on, if it has been
longer than a week since a verify last completed.
