HAC Nodes

HAC Nodes are indicated with the HAC Node icon in the tree model. HAC nodes manage the local instances of the system, and communicate with other nodes to maintain the desired overall status of the system. If texts in the node elements is displayed with a bold fonts, all changes are not applied to the host.

HAC Nodes

To add a HAC Node on a system server, right-click the HAC Nodes title and choose Add HAC Node. Enter the HAC Node's name that describes the location or function of the server, such as Cctr1 or Training13, and the server's IP address. For more information, see Installing HAC Nodes.

Context menu items depend on the mode, they are listed in the table below.
