Add Resource Group Wizard - Service IP label

Use this page to configure one or more Service IP labels for use by the resource group to be made highly available across multiple nodes.

The resource group uses the configured IP labels to provide services and to connect clients to an application running on a node. By default, a service IP label can be acquired by multiple nodes, although it is configured on only one node at any given time.

All fields on this page are inactive until you specify information for the Service IP Label field, then all fields are enabled.

Fields

Service IP label
Select an IP label from a list of discovered and available service IP labels. Or, you can specify a resolvable IP label manually.
Network name
Select the name of the network to which the service IP label is to be bound. Or, you can specify the network name manually. The name must consist of a minimum of one alphanumeric character and a maximum of 64 alphanumeric characters. You can use alphabetic characters of A - Z and a - z, numbers of 0 - 9, as well as underscore (_) characters. A name cannot begin with a number and cannot be a PowerHA™ reserved word.
Netmask (IPv4) / Prefix length (IPv6)
This field specifies either an optional netmask for an Internet Protocol version 4 (IPv4) address or an optional prefix length for an Internet Protocol version 6 (IPv6) address. A default value is provided based on the value specified for the Service IP label.

For an IPv4 label or address, you can specify a netmask in the range of 1 - 32, or in the format n.n.n.n, where n is a valid IP address value between 0 - 255 (for example, 0.0.0.255). You must specify a netmask for an IPv4 address when the underlying network is IPv6. A specified netmask is ignored when the service IP label or IPaddress and the underlying network are both IPv4.

For an IPv6 label or address, you can specify a prefix length in the range of 1 - 128. You must specify a prefix length for an IPv6 address when the underlying network is IPv4. A specified prefix length is ignored when the service IP label or IP address and the underlying network are both IPv6.

Actions

Add Another
Click Add Another to add another set of fields so that you can configure another service IP label for the resource group. All fields for the added service IP label are inactive until you specify information for the Service IP Label field, then all fields are enabled.
Remove
Click Remove to remove the content from the first set of service IP label fields and disable all fields after the Service IP label field. If applied to an added service IP label on the page, this action removes the entire set of fields for the added service IP label.
