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.
Automatically fallover
- 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
PowerHA SystemMirror
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.
