Advanced configuration 277 Managing node clusters Note: SuperUsers can establish a cluster master node; Administrators, StandardUsers, and RestrictedUsers cannot. See "User groups reference" on page 319 for more about permissions. Adding slave nodes to clusters Symantec Network Security provides a way to add both Network Security software nodes and 7100 Series appliance nodes to a cluster, using the topology tree. Add a slave node to the topology tree after you install Symantec Network Security on the corresponding slave computer. Similarly, add a 7100 Series node to the topology tree after performing the initial configuration of the appliance itself. When you add slave nodes to the topology tree, make a note of the node number that you assign. You must supply the same number when you perform the initial configuration of the appliance, and when you install Symantec Network Security software on a designated computer. See the following for additional related information: ■ See "Adding or editing software nodes" on page 86. ■ See "Adding or editing 7100 Series nodes" on page 92. ■ See "Configuring availability for multiple nodes" on page 289. Caution: Verify that Network Time Protocol (NTP) is not running on any slave node within a cluster. If a slave node is running NTP, it cannot synchronize with the master node, which can cause the slave node to malfunction. Note: SuperUsers can add both Network Security software nodes and 7100 Series appliance nodes to a cluster and assign them master and slave status. See "User groups reference" on page 319 for more about permissions. Deleting nodes from clusters Symantec Network Security provides a way to delete both Network Security software nodes and 7100 Series appliance nodes from a cluster, using the topology tree. See "Deleting objects" on page 81.
