Setting Up and Connecting the Hardware

When you have the necessary hardware and software, you are ready to set up the hardware for your cluster.

For instructions on setting up and configuring the cluster hardware, see the following sections. Perform these tasks in sequential order.

Setting Up the Netra T1 Servers

To install the Netra T1 servers, see the documentation provided with the hardware or go to the following site:

http://www.sun.com/products-n-solutions/hardware/docs/Servers

Setting Up the Terminal Server

To install the terminal server, see the documentation provided with your terminal server.

Setting Up and Configuring the Ethernet Switches

A Foundation Services cluster must have a redundant network, that is, two network interfaces that back each other up. To make a network redundant, a cluster requires two Ethernet switches. The Foundation Services have been validated on Cisco Catalyst 29x0 Desktop Switches. If you use other switches, make sure that the switches support the following:

  • Simple Network Management Protocol (SNMP)

  • Management information base (MIB) RFC 1213 and RFC 1493

  • Configuration that permits disabling of the Spanning Tree Protocol (STP)

Setting Up and Configuring the Installation Server

The installation server enables you to install the Solaris operating system and the Foundation Services on the cluster by using the Solaris JumpStart™ software.

The installation server requires the following:

Hardware requirements

UltraSPARC® platform

Two network devices. One network device is used to connect the installation server to an external network. The other network device is used to connect the installation server to the cluster network

Operating system

Solaris. See the Netra High Availability Suite Foundation Services 2.1 6/03 Release Notes for information about the supported software versions

Software requirements

Perl Version 5, which is available in the Developer Solaris Software Group

The Foundation Services software distribution

Disk capacity

Minimum 1.5 Gbytes for a Solaris software distribution

This size does not include applications that you might want to run on the cluster

Free space

Minimum 1.5 Gbytes after the Solaris operating system has been installed

Connecting the Hardware

The following diagram illustrates a cluster of three nodes: two master-eligible nodes and one diskless node.

Figure 2-1 Connecting the Hardware

Illustration shows how to connect the nodes, terminal server, switches, and installation server.

The nodes of your cluster are connected to each other through switches. You can connect the console of each node to the terminal server to provide access to the console of the node. Connect the installation server to the cluster network through a switch. To enable console access, connect the serial port of the nodes to the terminal server.

The cluster nodes must not be on the same physical wire as the nodes of another cluster. When a diskless node boots, it sends a broadcast message to find the master node. If two clusters share the same wire, the diskless node could receive messages from the wrong master node.
