## Preparing the Nodes and Disks

This section contains the procedures that you need to prepare the nodes and disks.

Note - The following steps are based on the configurations that are described in Standard Data Service Configurations.

## How to Prepare the Nodes for a Failover Configuration

Use this procedure to prepare for the installation and configuration of WebLogic Server in a failover configuration.

1. Create a failover resource group to hold the logical hostname and the WebLogic Administration Server resources.

       # clresourcegroup create [-n nodelist] RG1

2. Add the logical host name resource.

   The logical-host–1 is the host name the WebLogic Administration Server will be listening on. This host name can be set from the WebLogic console.

       # clreslogicalhostname create -g RG1 logical-host-1

   Note - If you require a fully qualified host name, you must specify the fully qualified name with the `-h` option and you cannot use the fully qualified form in the resource name.

3. Bring the resource group online.

       # clresourcegroup online -M RG1

4. Create a failover resource group to hold the logical host name and the WebLogic Managed Server resources.

   Note - Depending on the number of WebLogic Servers and on the configuration planned, create the resource groups and the logical_hostname resources. Refer to Standard Data Service Configurations.

       # clresourcegroup create [-n nodelist] RG2

5. Add the logical host name resource.

   The logical-host-2 is the host name on which the WebLogic Administration Server will be listening.

       # clreslogicalhostname create -g RG2 logical-host-2

   Note - If you require a fully qualified host name, you must specify the fully qualified name with the `-h` option and you cannot use the fully qualified form in the resource name.

6. Bring the resource group online.

       # clresourcegroup online -M RG2

7. Create a highly-available local file system managed by the `HAStoragePlus` resource.

   For more information, see Chapter 5, Creating a Cluster File System, in Oracle Solaris Cluster Software Installation Guide

## How to Prepare the Nodes for a Multi-Master Configuration

Use this procedure to prepare for the installation and configuration of WebLogic Server in a multi-master configuration that uses single-node resource groups.

1. Create a failover resource group to hold the logical hostname and the WebLogic Administration Server resources.

       # clresourcegroup create [-n nodelist] RG1
       # clreslogicalhostname create -g RG1 logical-host-1
       # clresourcegroup online -M RG1

2. Create failover resource groups for the logical hostnames for the managed server.

       # clresourcegroup create -p nodelist=node1,node2 logicalhost-n1-rg
       # clresourcegroup create -p nodelist=node2,node1 logicalhost-n2-rg

3. Create logical hostname resources in the resource groups.

       # clreslogicalhostname create -g logicalhost-n1-rg -h logicalhost-n1 logicalhost-n1-rs
       # clreslogicalhostname create -g logicalhost-n2-rg -h logicalhost-n2 logicalhost-n2-rs

4. Bring the logical hostname resource groups online.

       # clresourcegroup online -emM logicalhost-n1-rg
       # clresourcegroup online -emM logicalhost-n2-rg

5. Create a cluster file system managed by the `HAStoragePlus` resource.

   For more information, see Chapter 5, Creating a Cluster File System, in Oracle Solaris Cluster Software Installation Guide

## How to Prepare the Nodes for a Multi-Instance Configuration

Use this procedure to prepare for the installation and configuration of WebLogic Server in a multi-instance configuration.

The procedure assumes two nodes in the cluster and implements the configuration shown in Figure 1-3.

1. Create a failover resource group to hold the logical hostname and the WebLogic Administration Server resources.

       # clresourcegroup create [-n nodelist] RG1
       # clreslogicalhostname create -g RG1 logical-host-1
       # clresourcegroup online -M RG1

2. Create failover resource groups for the logical hostnames for the managed server.

       # clresourcegroup create -p nodelist=node1,node2 logicalhost-n1-rg
       # clresourcegroup create -p nodelist=node2,node1 logicalhost-n2-rg

3. Create logical hostname resources in the resource groups.

       # clreslogicalhostname create -g logicalhost-n1-rg -h logicalhost-n1 logicalhost-n1-rs
       # clreslogicalhostname create -g logicalhost-n2-rg -h logicalhost-n2 logicalhost-n2-rs

4. Bring the logical hostname resource groups online.

       # clresourcegroup online -emM logicalhost-n1-rg
       # clresourcegroup online -emM logicalhost-n2-rg

5. Set the Failback property for each logical hostname resource group.

       # clresourcegroup set -p Failback=True logicalhost-n1-rg
       # clresourcegroup set -p Failback=True logicalhost-n2-rg

6. Create a cluster file system managed by the `HAStoragePlus` resource.
