Setting Auto Verify for a Unit
The Auto Verify policy causes verify tasks to be performed automatically.
This feature is designed to make verification of units easier.
If Auto Verify is set and there is no schedule set up for verify tasks, then the
controller firmware can initiate a verify task once every 24 hours. If verify
time windows are scheduled, then the controller will only start an automatic
verify task during the scheduled time windows. (For information about
schedules, see “Scheduling Background Tasks” on page 76.)
If Auto Verify is not set, you must manually specify when you want to run a
verify, on the 3DM
Controller Settings page. If a schedule is set for verify,
then the verify that you manually start will only run during the scheduled
time.
You can set the Auto Verify policy while creating a unit through 3DM or you
can change the setting later using the following method.
To set the Auto Verify policy for an existing unit
1 Choose
Management > Controller Settings from the menu bar in 3DM.
2In the
Unit Policies section of the Controller Settings page, check the
Auto Verify box for the appropriate unit. (To disable this policy, uncheck
the box.)
The page refreshes, and a message at the top confirms the change you
have made.
