2. Chapter 5 # Configuration Stage 1: Creating a Generic Flash Archive This chapter describes stage 1 of the configuration process. It describes how to complete the cluster configuration files, software configuration files, and the configuration files for Solaris JumpStart. This section describes how to create the cluster configuration files `cluster.conf`, `machine.conf`, and `network.conf`. If you are using an example hardware configuration, you can use the templates of the cluster configuration files provided with the product. For the example hardware configuration templates, see Templates for Example Hardware Configurations. Although template files are provided for the example hardware configurations, you may still need to make some modifications. When all the configuration files have been created, create a software load. In addition, create the Solaris JumpStart environment for the prototype machine. Then, you have to boot the prototype machine with the node group software. When the node group software has been installed on the prototype machine, a generic flash archive is created on the build server. When stage 1 has been completed, you have one or more generic flash archives for a generic cluster configuration. This chapter covers the following topics: Configuration Stage 1 Checklist Configuration Stage 1 Procedure Connecting the Prototype Machine to the Build Server SMCT Configuration File Locations Configuring the `cluster.conf` Configuration File Configuring the `machine.conf` Configuration File Configuring the `network.conf` File Creating a Software Configuration File for a Node Group Customizing Solaris JumpStart Files for the Prototype Machine Creating the Software Load Copying the Software Load to an Export Directory Creating the Solaris JumpStart Environment for the Prototype Machine Booting the Prototype Machine With the Node Group Software Creating a Generic Flash Archive ## Configuration Stage 1 Checklist Before you perform configuration stage 1, ensure that you have: Set up your hardware as described in Chapter 3, Installing the Hardware and Software Planned your deployment environment and your disk layout, as described in Chapter 4, Planning Your Deployment Created the SMCT environment by using the `nhsmctsetup` command, as described in Creating the SMCT Environment ## Configuration Stage 1 Procedure The following figure shows the configuration procedure for stage 1. Figure 5-1 Configuration Stage 1 ## Connecting the Prototype Machine to the Build Server Before you start configuration stage 1, make sure that you have edited the `install-server.conf` and `master-system.conf` files, as described in this section. For information about connecting the prototype machine to the cluster, see the Netra High Availability Suite Foundation Services 2.1 6/03 Hardware Guide. ### To Connect the Prototype Machine to the Build Server The files described in this section are used later in the procedure by the `flinstall` command. For more information on `flinstall`, see the `flinstall`(1M) man page. Log in to the build server as superuser. Copy the `install-server.conf` file from the `/opt/SUNWcgha/nhsmct/etc/models` directory to your chosen destination directory, smct-config-dir`/models`, removing the `*.tmpl` extension. For example:
       # cp /opt/SUNWcgha/nhsmct/etc/models/install-server.conf.tmpl /
       destination_dir/install-server.conf
4. Edit the `install-server.conf` file. For more information, see the `install-server.conf`(4) man page. Copy the `master-system.conf.tmpl` file from the `/opt/SUNWcgha/nhsmct/etc/models` directory to the smct-config-dir`/models` directory. While copying the file, remove the `*.tmpl` extension. For example:
       # cp /opt/SUNWcgha/nhsmct/etc/models/master-system.conf.tmpl /
       destination_dir/master-system.conf
2. Edit the `master-system.conf` file with the Ethernet address configuration. For more information, see the `master-system.conf`(4) man page. ## Configuring the Installation Server This section describes how to configure the connectivity and NFS accessibility of the installation server. ### To Configure and Activate the Network Interface That Is Connected to the Cluster Configure and activate the network interface that is connected to the target cluster. Ensure that the interface does not conflict with the cluster addressing that is assigned during the installation procedure. Check that the IP address is not already in use. If there is an addressing conflict, modify the addressing schema in the `master-system.conf` and `install-server.conf` files to resolve the conflict. ### To Modify the `/etc/nsswitch.conf` File Log in to the installation server as a superuser. Modify the `/etc/nsswitch.conf` file so that `files` is positioned before `nis` in the `hosts`, `ethers` and `bootparams` entries. For example:
       hosts: files nis
       ethers: files nis
       bootparams: files nis
