Installing the Solaris Operating System Over a 10-Gigabit Ethernet Network

The Solaris Advanced Installation Guide describes the full procedure for installing the Solaris Operating System over the network. The following procedure assumes that you have created an install server, which contains the image of the Solaris CD, and that you have set up the client system to be installed over the network.

Before you can install the Solaris Operating System on a client system with a 10- Gigabit Ethernet adapter, you must first add the 10-Gigabit Ethernet software packages to the install server. These software packages are on Sun 10-Gigabit Ethernet Driver CD.

Note – Refer to the Solaris Advanced Installation Guide for more information about installing the Solaris Operating System over the network.

▼To Install the Solaris Operating System Over a 10-Gigabit Ethernet Network

1.Prepare the install server and client system to install the Solaris Operating System over the network.

The Solaris Advanced Installation Guide describes how to create the install server and set up the client systems.

Note – If you want to install the client system over a network that is not part of the same subnet, you must also create a boot server. The Solaris Advanced Installation Guide describes how to create a boot server.
