Create a Cluster Wizard: Configure the Cluster

Use this page to provide basic cluster configuration information.

Fields

Cluster name
Specify a unique name for the cluster. The name must consist of 1 - 32 characters. You can use the characters A - Z and a - z, the numbers of 0 - 9, and the underscore (_) character.
Configure security
Select whether to configure security for the cluster. If you select Yes, you must provide security properties for the Configure Security page in this wizard. If you select No, the wizard does not include this page and the wizard creates the cluster without any security configuration.
Choose the sites
Select whether to use a multiple site configuration for your cluster.
Note: This property, and all subsequent properties, are available only if you are using PowerHA® SystemMirror 7.1 Enterprise Edition.
Cluster multicast address (IPv4)
Site 1 multicast address (IPv4)
Site 2 multicast address (IPv4)
Specify an Internet Protocol version 4 (IPv4) address that falls within the range 224.0.0.0 - 239.255.255.255. PowerHA SystemMirror uses this address for multicasting, which is the process of logically sending a single message to one or more peer nodes. The cluster manager uses this address to send control messages to the cluster nodes. By using multicasting, the cluster manager is able to more quickly distribute information to coordinate action within the cluster when a node failure occurs.

You must specify a single multicast address for the Cluster multicast address (IPv4) property when you configure two or more nodes for a single cluster without sites. If you configure a linked cluster with multiple sites, you also must specify a single cluster multicast address.

If you configure a stretched cluster with multiple sites, you must specify two multicast addresses, one address for each site, for the Site multicast address (IPv4) property.

If you do not specify a multicast address, the wizard creates one for you.

Choose cluster type
Select the type of cluster that you want to create:
Multisites with linked clusters
Select this option to create a full-featured infrastructure for the cluster. This option is useful for a cluster configuration that must handle long-distance data replication among nodes.
Multisites with stretched clusters
Select this option to create a more simplified infrastructure for the cluster. This option is useful for a cluster configuration that handles more limited distance data replication among nodes.
Site name 1
Site name 2
Specify a unique name for each site. The name must consist of 1 - 32 characters. You can use alphabetic characters of A - Z and a - z, numbers of 0 - 9, and the underscore (_) character.
Intersite recovery
Select the recovery action that PowerHA SystemMirror must take when the cluster manager cannot bring a resource group to an Online state on the primary site.
start of changeAutomatically falloverend of change
Select this option to have PowerHA SystemMirror automatically perform a fallover operation of the resource group to its backup site. This option is the default value.
Notify
Select this option to have start of changePowerHA SystemMirrorend of change use a notification method instead of taking an action to perform a fallover operation on the resource group. You must specify the location of the notification method to use this option.
Note: If you select this option. PowerHA SystemMirror puts the resource group into an ERROR state.
Notify script or executable file:
Specify the full path and file name of a user-defined script for PowerHA SystemMirror to use for the notification method when this resource fails.
