Change the Control Unit

Caution

The best method to change the control unit is to disable clustering on the control unit, wait for a new control election, and then re-enable clustering. If you must specify the exact unit you want to become the control unit, use the procedure in this section. Note that for centralized features, if you force a control unit change, then all connections are dropped, and you have to re-establish the connections on the new control unit.

To change the control unit, perform the following steps.

Procedure

Step 1

Open the Cluster Status dialog box by choosing Devices > Device Management > More (more icon) > Cluster Live Status.

You can also access the Cluster Status dialog box from Devices > Device Management > Cluster page > General area > Cluster Live Status link.

Step 2

For the unit you want to become the control unit, choose More (more icon) > Change Role to Control.

Step 3

You are prompted to confirm the role change. Check the checkbox, and click OK.
