Freezing a System
Freeze a system to prevent the service groups that it hosts from failing over to another system. Use this procedure before performing a system upgrade.
To freeze a system
-
In the [Cluster]:Systems view, in the Systems Listing table, click the linked name of the system that you want to freeze.
-
In the System:Summary view, in the Operations task panel, click Freeze.
-
In the Freeze System dialog box, select one or both of the following options:
-
Select Persistent if you want the system to retain a frozen state when the cluster is rebooted.
-
Select Evacuate if you want the system's active service groups to fail over to another system in the cluster before the freezing operation takes place.
-
Click OK.
You can freeze one or more systems at a time directly from the Cluster:Systems view by selecting the check boxes for systems in the Systems Listing table and then clicking Freeze in the Operations task panel.
