Create Cluster Wizard - Name the Cluster

Use this page to specify a name and a multicast address for the new cluster.

Fields

Cluster name
Specify a unique name for the new cluster. 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 reserved word. However, you can use reserved words when combined with numerals or another word (for example, my_network or rs232_02). You can find the most current list of reserved words in the file /usr/es/sbin/cluster/etc/reserved_words.
Cluster multicast address (IPv4)
Specify an Internet Protocol version 4 (IPv4) address that falls within the range of 224.0.0.0 to 239.255.255.255. This address is used for multicasting, which is a process of logically sending a single message to one or more peer nodes. The Cluster Manager uses this address to multicast control messages to the cluster nodes to speed the distribution of information needed to coordinate action when a node failure occurs.

If you do not provide a specific address, the wizard automatically creates one for the cluster.
