Preparing to Install Manually

After you have installed and connected the cluster hardware and the installation server, you are ready to manually install the Foundation Services on the cluster.

For more information, see the following sections:


Overview of the Manual Installation Process


TABLE 4-1 Tasks for Manually Installing and Configuring the Software

Task

Refer To

Prepare the installation environment.

Chapter 4

Manually install the Solaris Operating System and the Foundation Services on each master-eligible node.

Chapter 5

If you have diskless nodes, install the software for the diskless nodes on a shared partition of the disk of one master-eligible node.

OR

Chapter 6

If you have dataless nodes in your cluster, install the Solaris Operating System and the Foundation Services on the local disk of these nodes.

Chapter 7



Connecting the Installation Server

The installation server must be connected to the cluster through a switch.

1. Connect the installation server's second interface, NIC1, to the Ethernet switch connecting the NIC0 interfaces of the nodes.

For an illustration of how to connect the various components of a cluster, see the Netra High Availability Suite Foundation Services 2.1 7/05 Hardware Guide.

2. Log in to the installation server as superuser.

3. Create the file /etc/hostname.cluster-network-interface-name (hme0 in this procedure) on the installation server:

# touch /etc/hostname.hme0

4. Edit the /etc/hostname.hme0 file to add the host name of the installation server, for example, installation-server-cluster.

5. Choose an IP address for the network interface that is connected to the cluster, for example, 10.250.1.100.

6. Edit the /etc/hosts file on the installation server to add the IP address that you chose in Step 5

7. Set the netmask of the cluster network in the /etc/netmasks file:

10.250.1.0     255.255.255.0

l single-step bulletAdd the public host name and IP address of the installation server to the /etc/hosts file on your NIS server:


192.168.12.253	installation-server-public



Note - Do not add the IP address of the network interface that is connected to the cluster to the NIS server.




Preparing the Installation Environment

Before you manually install the software on the cluster, you must create the Solaris distribution on the installation server and prepare the installation server for manual installation.

To install the Solaris Operating System on the cluster, create a Solaris distribution on the installation server. The Solaris distribution is used to install the Solaris Operating System on the cluster nodes. If you are installing more than one Solaris distribution on the cluster, perform the steps in the procedure for each Solaris distribution.

1. Make sure that you have at least 1.5 Gbytes of free disk space on the installation server.

2. Log in as superuser on the installation server.

3. Create a directory for the Solaris distribution:

# mkdir Solaris-distribution-dir

where Solaris-distribution-dir is the directory where the distribution is to be stored on the installation server.

4. Change to the directory where the setup_install_server command is located:

# cd Solaris-dir/Solaris_x/Tools

5. Run the setup_install_server command:

# ./setup_install_server Solaris-distribution-dir

For more information about the setup_install_server command, see the appropriate documentation:

Before you begin the installation process, make sure that the installation server is configured correctly.

1. Configure the installation server as described in the Netra High Availability Suite Foundation Services 2.1 7/05 Hardware Guide.

2. If you are planning to install remotely from another system, open a shell window to connect to the installation server.

3. Confirm that the Solaris software packages that contain Perl 5.0 are installed on the installation server.

Use the pkginfo command to check for the SUNWpl5u, SUNWpl5p, and SUNWpl5m Perl packages.

4. Delete any entries for your cluster nodes in the following files:

5. Disable the installation server as a router by creating an /etc/notrouter file:

# touch /etc/notrouter

If a system running the Solaris Operating System has two network interfaces, the system is configured as a router by default. However, for security reasons, a Foundation Services cluster network must not be routed.

6. Modify the /etc/nsswitch.conf file on the installation server so that files is positioned before nis in the hosts, ethers, and bootparams entries:

hosts: files nis
ethers: files nis
bootparams: files nis

7. Connect to the console of each cluster node.


Choosing a Cluster Network

In the following chapters, you install and configure the Solaris Operating System and the Foundation Services on nodes of the cluster. One of the Foundation Services you can install and configure is the Carrier Grade Transport Protocol (CGTP). The CGTP enables a redundant network for your cluster.

You can choose not to install the CGTP if you want to configure a single network link for your cluster. In this case, if the network link fails, there is no backup network, and you might lose information.

For a complete description of the CGTP, see Carrier Grade Transport Protocol in the Netra High Availability Suite Foundation Services 2.1 7/05 Overview.
