Create and configure a cluster - assure_mimix - 6.0

To create and configure a new cluster, do the following:

1. Navigate to the Summary, Clusters or Replication portlet.

   

2. Click Configuration.

   The Configuration window displays.

   For detailed information refer to the Assure MIMIX for AIX online help.

   

3. Click New Cluster.

   This starts the Configuration wizard and the New Cluster - Cluster Name and Servers panel displays.

   This screen is displayed when there are only 2 servers configured in the instance.

   

   This screen is displayed when there are more than 2 servers configured in the instance.

   

   The Cluster Name and Servers panel contains the following fields:

   Field	Description
   Cluster Name and Servers—Section for specifying the name of the cluster, an optional description, and a portal connection for each server in the cluster.
   Cluster name	Specify the name of the cluster. Cluster names can be 256 characters long and can contain any alphanumeric character. Whitespace is not allowed.
   Description	Optional description for the cluster. Cluster descriptions can be 256 characters long and can contain any alphanumeric character. Whitespace is allowed.
   Server 1	Select from the list of portal connections that are associated with the instance. The host name from the portal connection is used for the server. This ensures the newly configured cluster will appear in the instance. If there are only two available portal connections, both drop-downs will default to the available portal connections. When a portal connection is selected from one drop-down, it will not be available in the other drop-down. If there are more than two servers: Select... Any portal connection that is in the instance domain and has not been selected for Server 1. If exactly two servers: One of the available portal connections.
   Server 2	Specify the portal connection for the second server in the cluster. If there are only two available portal connections, both drop-downs will default to the available portal connections.When a portal connection is selected from one drop-down, it will not be available in the other drop-down. If there are more than two servers: Select... Any portal connection that is in the instance domain and has not been selected for Server 1. If exactly two servers: One of the available portal connections.
