IBM 201 manual Using Families and Groups in the Tree View, v All Appliances, v Families

Appliances that are running the IAACU agent, but that have a network configuration that was not set by the IAACU agent or console, will appear in the Orphaned Externally Configured Appliances group. If an appliance is contained in the Orphaned Externally Configured Appliances group, you can use the Adopt By First Matching Family function to add it to a previously defined Family. For more information, see “Using the Adopt by First Matching Family Function” on page 14.

Using Families and Groups in the Tree View

Families are important elements of the IAACU. They specify the parameters that the IAACU uses to automatically categorize discovered appliances and to configure them with the appropriate network settings. Family rules are defined solely by appliance type or purpose. Each Family can contain only one type of appliance. The only way to automatically apply predetermined network settings to newly installed and discovered appliances is to create and use Families.

Appliances that match the rules criteria for a Family group can be automatically configured to use predefined network settings. A Family can be configured to allow appliances to use DHCP to configure their IP settings, or can be defined to automatically assign IP settings (such as primary gateway and DNS server addresses, assigning an IP address from a specified IP address range, and specifying a subnet mask). Host names for discovered appliances can also be defined so that they are allocated using either a prefix or appliance serial number.

The IAACU is not the only way to configure network settings. For example, network settings can be configured using Terminal Services for Windows or by attaching a keyboard and mouse to the appliance and using Windows Control Panel. If the appliance network settings have been configured by a method other than using the IAACU, the appliance will be discovered by the IAACU and it will be added to an appropriate Family, if one exists. Appliances that have been configured using a method other than the IAACU for which no appropriate family exists will appear in the Orphaned Externally Configured Appliances group.

The Tree View Pane contains the following items:

vAll Appliances

Every discovered appliance is listed in the tree view under All Appliances.

vFamilies

The Families group in the Tree View Pane shows all Families that have been defined, with appliances that have already been assigned to each Family nested beneath the Family name in the tree view. Families are defined by appliance purpose, so all appliances that appear in a given family are of the same type. If you select a Family from the Tree View Pane, a description of the Family and the rules that are used to define the selected Family display in the Information Pane. If you select an appliance from a Family in the Tree View Pane, the selected appliance network settings display in the Information Pane.

If you are not using DHCP, the IAACU automatically assigns one IP address per appliance, using available addresses within the range defined in the Family rules. When a Family’s IP address range has been exhausted, the IAACU automatically searches for other Families that have rules matching the appliance being configured. If a matching Family with an available address is found, the appliance will automatically be assigned to the Family that has available IP addresses. This enables you to define multiple Families, each of which uses a set of non-contiguous IP address ranges.

When an appliance is discovered on the network, the IAACU automatically searches all previously defined Families, starting with the first Family listed in the
