Booting From a WAN Boot Server
The WAN boot installation method enables you to boot and install software over a
wide area network (WAN) by using HTTP. To support booting the Sun SPARC
Enterprise M8000/M9000 server from a WAN boot server, you must have the
appropriate wanboot executable installed to provide the needed hardware support.
If you have added SPARC64 VII processors to your server, for example, you must
perform this procedure even if you have performed it previously, before the new
processors were added.
For information about WAN boot servers, refer to the Solaris 10 Installation Guide:
Network-Based Installations for the version of Solaris 10 OS that you are using. You
can find Solaris 10 OS documentation here:
http://docs.sun.com/app/docs/prod/solaris.10
▼ To Upgrade the wanboot Executable
1. Install the Solaris 10 OS on the WAN boot server.
Install the version of Solaris 10 OS that is required for your server. For
information about minimum software requirements, refer to “Supported
Firmware and Software Versions” on page 2.
2. Copy the wanboot executable from that Solaris release to the appropriate
location on the install server.
For more detailed information, refer to the Solaris 10 Installation Guide: Network-
Based Installations. For Solaris 10 8/07, for example, the information in the English
document is here:

If you do not upgrade the wanboot executable, the Sun SPARC Enterprise
M8000/M9000 server will panic, with messages similar to the following:
