Change the control unit

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.

Caution

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.

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 and choose the Add, Cluster page, General area, and 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 check box, and click OK.
