IMPORTANT: Be aware of the possibility of creating conflicting filters. For example, if
the RAM (in MB) field is used in multiple filters, make sure the effective logical operators
where each is used make sense for the MB values that you enter. You could have one filter
requiring exactly 512 MB of RAM and another accepting a device having at least 512 MB
of RAM. If those filters are both required for the device to match the rule (this is with the
AND condition existing between them), you’d have a conflict that causes the filter to fail
its purpose.
13 Because you can create multiple rules to be listed here, and the information configured in the
Rule Construction dialog box comprises one rule, repeat
Step 10 through Step 12 as necessary.
14 To enable this work rule, select the check box for the Enabled field.
After you exit this dialog box, you can see whether the work rule is enabled by viewing the
work rules listing on the Preboot Services page.
To enable or disable a rule after creating it, you must edit the work rule from the Preboot
Services page.
15 To force the image to be reapplied to the device, select the check box for the Force download
field.
By default, ZENworks imaging does not reimage a device containing the same image. This
option allows you to force the image to be reapplied to the device. For example, you might
want to refresh all of your lab devices for the next use of the lab.
IMPORTANT: Use this option cautiously, because you can create an endless loop when the
option remains selected after an image is applied. If you image a device that remains non-
registered after it is imaged, it is reimaged with the same image over and over each time it
boots. To prevent this, deselect this option after you have imaged the applicable devices.
16 After exiting the Rule Construction dialog box, you can manipulate the order and existence of
the listed rules:
Edit: Opens the Rule Construction dialog box in edit mode.
Move up/down: After adding rules, you can change the order in which they are to be executed.
You can only move one rule at a time. This order is important because the first rule that is found
in the listing to match the device is used to apply the bundle, and the remainder of the rules are
ignored.
Remove: Removes the selected rules.
17 Click either Apply or OK to save the changes.
29.4.5 Configuring the Server Referral List
Referral lists are used to make sure managed devices belonging to other ZENworks Management
Zones can access their home zone. For more information, see
Section 28.3.6, “Preboot Referral
Lists,” on page 328 .
To set up referral lists:
1 In the ZENworks Control Center, click the Configuration tab, which displays the following
Management Zone Settings section:
